Description

  The present invention relates to a character graphic display device, a program, and a recording medium for displaying scaled characters or graphics.

  Character data for displaying characters includes, for example, bitmap data and vector data.

  The bitmap data includes fixed coordinate values corresponding to the character shape and character size. By outputting fixed coordinate values to a display device such as a color liquid crystal display device, characters can be displayed on the display device. However, the bitmap data is fixed according to the character size. Therefore, the bitmap data must be prepared for each required character size.

  The vector data includes, for example, data indicating a character outline and data indicating strokes constituting the character. When vector data is output to a display device such as a color liquid crystal display device, the vector data must be scaled according to the size of characters displayed on the display device. By scaling the vector data, only one type of vector data is required even if there are many types of required character sizes. This is because the vector data is not fixed according to the character size. Therefore, even when there are many types of required character sizes, the capacity of the storage device for storing character data may be small.

  However, according to the vector data, after the vector data is scaled, a quantization error is generated by quantizing the scaled vector data by a predetermined method (for example, rounding off). The quantization error is a difference between a number before being quantized by a predetermined method and a number after being quantized by a predetermined method. For example, the difference between the number 4.6 before rounding and the number 5 after rounding is 0.4. In this case, the quantization error is 0.4.

  FIG. 20 shows an example in which scaling data generated by scaling vector data indicating the character “day” is displayed as 16 dots × 16 dots. The line widths W10, W20, and W30 next to the character “day” all have the same thickness. Further, the intervals H10 and H20 between the lines of the character “day” are all the same interval.

  FIG. 21 shows an example in which quantized data generated by quantizing the scaled vector data by rounding off is displayed as 16 dots × 16 dots.

  By quantizing the scaling data, the intervals H10 and H20 are changed to the intervals H11 and H21, and the line widths W10, W20, and W30 are changed to the line widths W11, W21, and W31. Although H11 = H21, as a result of the quantization error, W11 = W31 ≠ W21.

  Patent Document 1 discloses a technique for obtaining the widths of a plurality of lines indicated by vector data after scaling based on the widths of the plurality of lines indicated by vector data before scaling. According to the technique disclosed in Patent Document 1, when the widths of the plurality of lines indicated by the vector data before scaling are the same, the widths of the plurality of lines indicated by the vector data after scaling are also the same. In addition, the scaled vector data is corrected. However, according to this technique, the corrected line widths W12, W22, and W32 are the same (W12 = W22 = W32). However, the distances H12 and H22 between the lines are different (see FIG. 22).

Patent Document 2 discloses a technique for correcting not only the line width but also the distance between lines so as to be a value that can be originally obtained. Since the plurality of line widths originally obtained are the same, the corrected line widths W13, W23, and W33 are corrected to be the same (W13 = W23 = W33). Furthermore, since the intervals between the plurality of lines that are originally obtained are the same, the corrected intervals H13 and H23 are corrected to be the same (see FIG. 23).

  However, in the technique described in Patent Document 2, the contour is moved so that the line width and the line interval are originally obtained, and therefore, it may not be possible to display 16 dots × 16 dots. This is because quantization errors accumulate.

  FIG. 24 shows an example in which vector data indicating the character “day” is displayed in 256 dots × 256 dots. The line widths W14, W24, and W34 are all the same, but the line intervals H14 and H24 are different.

  FIG. 25 shows an example in which the contour is corrected to move to a value originally obtained by the technique described in Patent Document 2. As a result of moving the contours so that the corrected line widths W15, W25, and W35 are all the same and the corrected line intervals H15 and H25 are different, it is impossible to display 16 dots × 16 dots.

  The present invention has been made to solve the above-described problem, and is a character graphic display device, a program, and a program capable of maintaining the width of lines and the interval of lines included in characters and graphics in a desired state before and after adjustment. An object is to provide a recording medium.

  Further, among the distances between the specific reference points, at least two distances may be different from each other.

  Further, the target value may be obtained by quantizing the width of the distance between the maximum reference point having the maximum value and the minimum reference point having the minimum value among the scaled reference points.

  Further, the adjusting means may include information predetermined for the distance between the scaled reference points, or information calculated from the distance between the scaled reference points after the reference points are scaled. Based on either, the width of the at least one distance and the width of the at least one other distance are such that the width of the at least one distance and the width of the at least one other distance are the same. Either one may be adjusted.

  Furthermore, it further comprises first determination means for determining whether or not the total of the quantized distance widths is larger than the target value, and the adjusting means is configured such that the quantized distance width total is the target distance. If it is determined that the distance is less than the value, the distance between the quantized distances having the maximum round-down width and the distance width defined as being equal to the distance having the maximum round-down width are all When the total of the quantized distance widths is determined to be larger than the target value, the distance width having the maximum round-up width among the quantized distances, and the maximum The distance width defined to be equal to the distance width having the rounded width may all be reduced by one.

  Furthermore, a second determination means for determining whether or not the number of distances defined as being equal to the width of the distance having the maximum round-down width is larger than the width to be adjusted, and the distance width having the maximum round-up width. And at least one of third determination means for determining whether or not the number of distances defined to be equal is larger than the width to be adjusted, wherein the adjustment means has a width of the quantized distance. If it is determined that the total is less than the target value and the number of distances defined to be equal to the width of the distance having the maximum devaluation width is not greater than the adjustment width, the maximum devaluation The distance widths defined as being equal to the width of the distance having widths are all increased by one, the sum of the quantized distance widths is determined to be greater than the target value, and the maximum round-up If it is determined that the number of distances defined as being equal to the width of the distance having no greater than the width to be adjusted, all the distance widths defined as being equal to the width of the distance having the maximum round-up width It may be decreased by one.

  Further, the adjusting unit may increase or decrease the width of at least one distance among the distances between the quantized reference points only once after generating the scaled reference points.

  Further, a first quantization error between the maximum reference point and the maximum reference point after quantization generated by quantizing the maximum reference point with the first method is the minimum reference point and the minimum reference point. Third display means for determining whether or not a point is larger than a second quantization error with a minimum reference point after quantization generated by quantizing the point by the first method, the display means If it is determined that the first quantization error is smaller than the second quantization error, the maximum reference point after the quantization is set as the reference coordinate value of the displayed character or figure, and the first When it is determined that the quantization error is larger than the second quantization error, the minimum reference point after the quantization may be used as the reference coordinate value of the displayed character or figure.

  FIG. 4 shows inter-reference point data included in the character data 142 of the character “middle” shown in FIG.

  The reference point serves as a calculation base for scaling each character in a well-balanced manner when scaling the character, and is determined appropriately for each character. This reference point is included in a block constituting the character. The reference point can be set not only along the X-axis direction of the character outline but also along the Y-axis direction. Further, the reference point does not necessarily have to be set on the outline of the character, and may be, for example, in a blank place between the outline of the character.

  The present invention does not depend on the font type of the character, and can be applied to the stroke font as in the case of the outline font described above.

It shows that. For example, the “same distance flag” indicated by the value “2” indicates that, among the distances X1 to X11, the distance X2 and the distance X10 are adjusted to the same size. For example, the “same distance flag” indicated by the value “3” indicates that, among the distances X1 to X11, the distance X4 and the distance X8 are adjusted to the same size. For example, the distance X6 to which the “same distance flag” indicated by the value “x” is attached indicates that there is no distance adjusted to the same size among the distances X1 to X11.

For example, in the “same distance flag” indicated by the value “1”, the distance Y1, the distance Y3, the distance Y5, the distance Y7, the distance Y9, and the distance Y11 among the distances Y1 to Y11 are adjusted to the same size. It shows that. For example, the “same distance flag” indicated by the value “2” indicates that the distance Y2 and the distance Y4 out of the distances Y1 to Y11 are adjusted to the same size. For example, the “same distance flag” indicated by the value “3” indicates that the distance Y8 and the distance Y10 among the distances Y1 to Y11 are adjusted to the same size. For example, the distance Y6 with the “same distance flag” indicated by the value “x” indicates that there is no width of the distance adjusted to the same size among the distances Y1 to Y11. According to the “same distance flag”, the width of at least one distance among the widths of a plurality of distances and the width of at least one other distance defined to be equal to the width of the at least one distance are indicated. Can do.

  The “distance flag” indicates whether or not it has a minimum required distance width as a distance width between reference points along the Y axis. Further, the distance flag also indicates how much the minimum necessary distance width is as the distance width between the reference points. For example, the distance flag of the distance Y1 is “1”. That the distance flag is “1” indicates that the distance Y1 has a minimum required distance width “1”.

  The “omission flag” indicates whether or not the width of the distance to be adjusted can be set to “0” when the width of the distance between the reference points along the Y axis is adjusted by grid fitting. Furthermore, the omission flag indicates the order in which the width of the distance to be adjusted is “0” when the width of the distance to be adjusted can be “0”. For example, the abbreviated flag for the distance Y4 indicates “3”. That is, the order of setting the width of the distance to be adjusted to “0” is the third.

  FIG. 8 shows the display processing procedure of the present invention. The display processing procedure is realized by the CPU 121 executing the character display program 141.

  Hereinafter, the display processing procedure of the present invention will be described step by step with reference to FIG.

  Step S101: Character information indicating characters to be displayed on the display device 130 is input to the main memory 122 via the input device 110. In accordance with the input character information, the CPU 121 reads character data 142 stored in the auxiliary storage device 140 from the auxiliary storage device 140. The read character data 142 includes coordinate data (see FIG. 3) and data between reference points (see FIG. 4).

  Step S102: The CPU 121 scales the coordinate data according to the character size output to the display device 130, and generates scaled coordinate data. Step S102 is processed by the CPU 121 executing the program 141a. The scaled coordinate data is stored in the main memory 122.

  When the character size to be output is n dots, the scaled coordinate data (X, Y) is, for example, (n × X / 256, n × Y / 256). The scaled coordinate data is calculated to the second decimal place.

  FIG. 9 shows the coordinate data included in the character data 142 of the character “middle” and the coordinate data after scaling the coordinate data. The coordinate data before scaling is the coordinate data shown in FIG.

  “X coordinate” indicates an X coordinate component of coordinates before scaling. “Y coordinate” indicates the Y coordinate component of the coordinates before scaling.

  “X coordinate after scaling” indicates the X coordinate component of the coordinate after scaling. “Y coordinate after scaling” indicates a Y coordinate component of the coordinate after scaling.

  When the character size to be output is 16 dots, the point P1 (143, 240) before scaling is changed to the point P1 (8.94, 15.00) after scaling by scaling.

  FIG. 10 shows the coordinate data included in the character data 142 of the character “Crystal” and the coordinate data after scaling these coordinate data.

  The coordinate data before scaling is the coordinate data shown in FIG.

  “X coordinate after scaling” indicates the X coordinate component of the coordinate after scaling. “Y coordinate after scaling” indicates a Y coordinate component of the coordinate after scaling.

  When the character size to be output is 16 dots, the point P1 (219, 254) before scaling is changed to the point P1 (13.69, 15.88) after scaling by scaling.

  The description of the display processing procedure of the present invention will be continued with reference to FIG. 8 again.

  Step S103: The CPU 121 performs grid fitting on the scaled coordinate data to generate grid-fitted coordinate data. Step S103 is processed by the CPU 121 executing the program 141b. The grit-fitted coordinate data is stored in the main memory 122.

  Details of the grid fitting processing procedure will be described later.

  Step S104: The CPU 121 generates drawing data so that the coordinate data subjected to grid fitting can be displayed on the display device. The generation of drawing data is known as a method for generating data indicating an outline font. For example, the CPU 121 generates drawing data indicating the outline of a character by a curve drawing program such as straight line drawing or spline, and fills the inside of the outline by a filling program. As the CPU 121 executes the program 141c, step S104 is executed. The generated drawing data is stored in the main memory 122.

  Step S105: The CPU 121 displays the drawing data generated in step S104 on the display device 130.

  FIG. 11 shows the grid fitting process procedure (the process procedure of step S103 of the program 141b). The program 141b is executed by the CPU 121. FIG. 11A shows steps S301 to S310 and steps S327 to S330. FIG.11 (b) shows step S319-step S326. FIG.11 (c) shows step S311-step S318.

  “Distance” indicates the width of the distance in the X-axis direction between the reference points after the grid fitting process. For example, the distance width of the distance X1 is “2.00”.

  “Distance after quantization” indicates the width of the distance generated by quantizing the value indicated in “distance”. For example, the width of the distance generated by quantizing the distance X1 is “2”. Details of the quantization will be described later.

  The “first error” indicates the amount of change from the value indicated by “distance after quantization” to the value indicated by “distance”. For example, when the distance X2 is targeted, the amount of change from the value indicated by “distance after quantization” to the value indicated by “distance” is “−0.44 (ie, 3-3.44). ) ”.

  The “same distance flag” indicates at least one distance among the widths of a plurality of distances, and a width of at least one other distance adjusted to the same size as the at least one distance. For example, the “same distance flag” indicated by the value “1” indicates that among the distances X1 to X5, the distance X1, the distance X3, and the distance X5 are adjusted to the same size. For example, the “same distance flag” indicated by the value “2” indicates that, among the distances X1 to X5, the distance X2 and the distance X4 are adjusted to the same size. According to the “same distance flag”, the width of at least one distance among the widths of a plurality of distances and the width of at least one other distance defined to be equal to the width of the at least one distance are indicated. Can do.

  The “distance after the same distance processing” indicates the width of the distance generated by performing the same distance processing on the distance width after quantization. For example, when the distance X1, the distance X3, and the distance X5 are targeted, each of the distance widths after the same distance process is “2”. For example, when the distance X2 and the distance X4 are targeted, each of the distance widths after the same distance process is “3”. The details of the same distance process will be described later.

  The “second error” indicates the amount of change from the value indicated by “distance after the same distance process” to the value indicated by “distance”. For example, when the distance X2 is targeted, the amount of change from the value indicated by “distance after the same distance process” to the value indicated by “distance” is “−0.44 (ie, 3-3. 44) ".

  FIG. 12B shows data between reference points after grid fitting processing is performed on data between reference points in the Y-axis direction (see FIG. 4B).

  The “same distance flag” indicates at least one distance among the widths of a plurality of distances, and a width of at least one other distance adjusted to the same size as the at least one distance. For example, the “same distance flag” indicated by the value “1” indicates that the distance Y2 and the distance Y4 out of the distances Y1 to Y5 are adjusted to the same size. For example, the “same distance flag” indicated by the value “1” indicates that the distance Y2 and the distance Y4 out of the distances Y1 to Y5 are adjusted to the same size. For example, the “same distance flag” indicated by “x” indicates that there is no width of the distance adjusted to the same size as each of the distance Y1, the distance Y3, and the distance Y5 among the distances Y1 to Y5. . According to the “same distance flag”, the width of at least one distance among the widths of a plurality of distances and the width of at least one other distance defined to be equal to the width of the at least one distance are indicated. Can do.

  The “distance after the same distance processing” indicates the width of the distance generated by performing the same distance processing on the distance width after quantization. For example, when the distance Y2 and the distance Y4 are targeted, each of the distance widths after the same distance processing is 2. For example, since the same distance flag “x” is attached to the distance Y1, the distance Y3, and the distance Y5, the same distance process for the distance Y1, the distance Y3, and the distance Y5 is not performed. Therefore, the distance width after the same distance processing for the distance Y1, the distance Y3, and the distance Y5 is the same as the distance width before the same distance processing. The details of the same distance process will be described later.

  The “second error” indicates the amount of change from the value indicated by “distance after the same distance process” to the value indicated by “distance”. For example, when the distance Y2 is the target, the amount of change from the value indicated by “distance after the same distance process” to the value indicated by “distance” is “0.00 (that is, 2-2.00). ) ”.

  The “distance after quantization” indicates the width of the distance generated by quantizing the value shown in “distance” by the second method. For example, the width of the distance generated by quantizing the distance X1 by the second method is “1”. Details of the quantization by the second method will be described later.

  The “first error” indicates the amount of change from the value indicated by “distance after quantization” to the value indicated by “distance”. For example, when the distance X2 is targeted, the amount of change from the value indicated by “distance after quantization” to the value indicated by “distance” is “−0.44 (ie, 0−0.44). ) ”.

It shows that. For example, the “same distance flag” indicated by the value “2” indicates that, among the distances X1 to X11, the distance X2 and the distance X10 are adjusted to the same size. For example, the “same distance flag” indicated by the value “3” indicates that, among the distances X1 to X11, the distance X4 and the distance X8 are adjusted to the same size. For example, the distance X6 to which the “same distance flag” indicated by the value “x” is attached indicates that there is no width of the distance adjusted to the same size among the distances X1 to X11.

  The “distance after the same distance processing” indicates the width of the distance generated by performing the same distance processing on the distance width after quantization. For example, when the distance X1, the distance X3, the distance X5, the distance X7, the distance X9, and the distance X11 are targeted, each of the distance widths after the same distance process is “1”. For example, when the distance X2 and the distance X10 are targets, each of the distance widths after the same distance process is “0”. For example, when the distance X4 and the distance X8 are targeted, each of the distance widths after the same distance process is “3”. For example, the distance X6 does not have a distance adjusted to the same size among the distances X1 to X11. Therefore, when the distance X6 is targeted, the width of the distance after the same distance processing is “2”, which is the same as the width of the distance before the same distance processing.

  The “second error” indicates the amount of change from the value indicated by “distance after the same distance process” to the value indicated by “distance”. For example, when the distance Y2 is the target, the amount of change from the value indicated by “distance after the same distance processing” to the value indicated by “distance” is “−0.44 (that is, 0-0. 44) ".

  FIG. 13B shows data between reference points after grid fitting processing is performed on the data between reference points in the Y-axis direction (see FIG. 7B).

  The “first error” indicates the amount of change from the value indicated by “distance after quantization” to the value indicated by “distance”. For example, when the distance Y2 is the target, the amount of change from the value indicated by “distance after quantization” to the value indicated by “distance” is “0.44 (ie, 3-2.56). Is.

  As described above, the “same distance flag” includes at least one distance among a plurality of distance widths and at least one other distance width adjusted to the same size as the at least one distance. Show. For example, in the “same distance flag” indicated by the value “1”, the distance Y1, the distance Y3, the distance Y5, the distance Y7, the distance Y9, and the distance Y11 among the distances Y1 to Y11 are adjusted to the same size. It shows that. For example, the “same distance flag” indicated by the value “2” indicates that the distance Y2 and the distance Y4 out of the distances Y1 to Y11 are adjusted to the same size. For example, the “same distance flag” indicated by the value “3” indicates that the distance Y8 and the distance Y10 among the distances Y1 to Y11 are adjusted to the same size. For example, the distance Y6 with the “same distance flag” indicated by the value “x” indicates that there is no width of the distance adjusted to the same size among the distances Y1 to Y11. According to the “same distance flag”, the width of at least one distance among the widths of a plurality of distances and the width of at least one other distance defined to be equal to the width of the at least one distance are indicated. Can do.

  The “distance after the same distance processing” indicates the width of the distance generated by performing the same distance processing on the distance width after quantization. For example, when the distance Y1, the distance Y3, the distance Y5, the distance Y7, the distance Y9, and the distance Y11 are targeted among the distances Y1 to Y11, each of the distance widths after the same distance processing is “1”. . For example, when the distance Y2 and the distance Y4 are targeted among the distances Y1 to Y11, each of the distance widths after the same distance process is “3”. For example, when the distance Y8 and the distance Y10 are targeted among the distances Y1 to Y11, each of the distance widths after the same distance process is “2”. Since the same distance flag “x” is attached to the distance Y6, the same distance processing for the distance Y6 is not performed. Therefore, the distance width after the same distance processing for the distance Y6 is the same as the distance width before the same distance processing.

  The “second error” indicates the amount of change from the value indicated by “distance after the same distance process” to the value indicated by “distance”. For example, when the distance Y2 is the target, the amount of change from the value indicated by “distance after the same distance processing” to the value indicated by “distance” is “0.44 (ie, 3-2.56). ) ”.

  The “distance after one adjustment” indicates the result of narrowing the distance width of the “distance after quantization” to which the predetermined value of the “same distance flag” is attached. For example, the “distance after one adjustment” value “2” from the “distance after quantization” value “3” corresponding to the distance Y2 and the distance Y4 to which the value “2” of the “same distance flag” is attached. ”. Details of the process of reducing the width of the quantized distance will be described later.

  The “third error” indicates the amount of change from the value indicated by “distance after one adjustment” to the value indicated by “distance”. For example, when the distance Y2 is the target, the amount of change from the value indicated by “distance after one adjustment” to the value indicated by “distance” is “−0.56 (that is, 2-2. 56) ".

  The “adjusted flag” is attached to an object (distance) whose length has been adjusted by the process of changing the width of the quantized distance. For example, since the “distance after quantization” corresponding to the distance Y2 and the distance Y4 is adjusted, a value “1” is assigned to the distance Y2 and the distance Y4.

  The “distance after two adjustments” indicates a result of widening the distance of “distance after quantization” to which a predetermined value of “same distance flag” is attached. For example, the value “1” of “distance after quantization” corresponding to the distance Y6 to which the value “x” of “same distance flag” is attached is expanded to the value “2” of “distance after two adjustments”. ing. The details of the process of expanding the quantized distance will be described later.

  The “fourth error” indicates the amount of change from the value indicated by “distance after two adjustments” to the value indicated by “distance”. For example, when the distance Y6 is targeted, the amount of change from the value indicated by “distance after two adjustments” to the value indicated by “distance” is “0.56 (ie, 2-1.44). ) ”.

  The “adjusted flag” is attached to an object (distance) whose length has been adjusted by the process of changing the width of the quantized distance. For example, since “the distance after quantization” corresponding to the distance Y6 is adjusted in addition to the “distance after quantization” corresponding to the distance Y2 and the distance Y4, in addition to the distance Y2 and the distance Y4, The value “1” is attached.

  Hereinafter, the details of the grid fitting process procedure will be described step by step with reference to FIGS.

  First, step S301 to step S310 and step S330 will be described with reference to FIG.

  Step S301: The CPU 121 calculates the width of the distance between a plurality of reference points obtained to the second decimal place by scaling (see “Distance” in FIGS. 12 and 13).

  Step S302: The CPU 121 obtains a target value indicating the width of the target distance based on the distance width between the plurality of reference points obtained to the second decimal place by scaling.

  Specifically, the CPU 121 obtains a value obtained by subtracting the minimum X coordinate value from the maximum X coordinate value among the distances between the plurality of reference points obtained to the second decimal place by scaling. Is rounded off to obtain a target value indicating the target distance width in the X-axis direction. The CPU 121 calculates a value obtained by subtracting the minimum Y coordinate value from the maximum Y coordinate value among the distances between the plurality of reference points calculated to the second decimal place by scaling, and further, this value is quantized by rounding off. By doing this, a target value indicating the width of the target distance in the Y-axis direction is obtained.

  The CPU 121 adds all the distance widths between the plurality of reference points obtained to the second decimal place by scaling, and quantizes the obtained value by rounding to obtain a target distance in the X-axis direction. It is possible to obtain a target value that indicates the width of. Further, the CPU 121 adds all the widths of the distances between the plurality of reference points obtained to the second decimal place by scaling, and quantizes the obtained values by rounding to obtain a target distance in the Y-axis direction. It is possible to obtain a target value that indicates the width of.

  By generating a total quantized by rounding off, it is possible to unify the size of characters.

  Note that rounding is used as the quantization method, but the quantization method is not limited to rounding. When making a character appear as large as possible, rounding up may be used as a method of quantization. If the characters are shown as small as possible, truncation may be used as a method of quantization. It is possible to use a desired threshold when quantizing.

  Further, the target value is not limited to being obtained by quantizing the total width of the distance between the plurality of scaled reference points. The user may input a desired value to the character display device 100 as a target value.

  As described above, by executing step S302, the values obtained based on the plurality of reference points obtained up to the second decimal place by scaling are quantized by the first method, and the target value is determined later. Thus, a plurality of values to be adjusted can be obtained.

  Step S303: The CPU 121 quantizes each width of the distance between the plurality of scaled reference points by rounding off. In the example shown in FIG. 12 and FIG. 13, the width of the distance between the plurality of scaled reference points is indicated by “distance”, and the width of the distance between the plurality of reference points quantized is “quantization”. It is shown in “After Distance”.

  Note that the quantization may be performed in consideration of the distance flag. The distance flag indicates the minimum distance required as the distance between the plurality of reference points. For example, when the distance width between two scaled reference points is “2.4”, if there is no distance flag, the distance width quantized by rounding is “2”. If the distance flag is “1”, the distance width quantized by rounding is “2”. If the distance flag is “2”, the distance width quantized by rounding is “2”. However, if the distance flag is “3”, the width of the quantized distance is set to “3” by considering the distance flag.

  Although rounding is used as a method for quantizing the distance width, the method for quantizing the distance width is not limited to rounding. As a method of quantizing the distance width, rounding up may be used, or rounding down may be used. Alternatively, a desired threshold value may be used as a method for quantizing the distance width.

  The quantization method in the first method for calculating the target value performed in step S302 may be the same as or different from the quantization method in the second method for quantizing the width of the distance between the reference points obtained in step S303. It may be. For example, rounding may be used as the first method for quantization, and rounding may be used as the second method for quantization. When making a character appear as large as possible, rounding may be used as the first method for quantization, and rounding may be used as the second method for quantization.

  Step S304: The CPU 121 refers to a predetermined same distance flag and adjusts the widths of a plurality of distances to which the same distance flag having the same value is attached to the same value. The distance width after the adjustment is indicated by “distance after the same distance process” in the examples shown in FIGS. 12 and 13.

  As described with reference to FIGS. 12 and 13, among the distances quantized by the second method, at least one distance and the width of the at least one distance are considered to have the same width. And at least one other distance. A distance considered to have the same width is a distance indicated by the same value of the “same distance flag”.

  Note that the fact that at least one distance and at least one other distance are adjusted to the same size can mean that the width of at least one distance is equal to the width of at least one other distance. For example, the “distance after quantization” corresponding to the distance X1, the distance X3, and the distance X5 is the value “2”, which is equal (see FIG. 12A).

  Step S305: The CPU 121 determines whether or not the total distance width after the same distance processing is the same as the total (target value) quantized by the first method.

  If it is determined that they are the same (Yes), it is not necessary to adjust the positions of the plurality of reference points again, and the process proceeds to step S327. If it is determined that they are not the same (No), the process proceeds to S306. When it is determined that they are not the same (No), the total distance width after the same distance processing is larger than the total quantized by the first method, or the total distance width after the same distance processing is This is the case when it is smaller than the sum quantized by the first method.

  Step S306: The CPU 121 determines whether or not the total distance width after the same distance processing is smaller than the total (target value) quantized by the first method.

  If it is determined that it is not small (No), the process proceeds to step S307. If it is determined to be small (Yes), the process proceeds to step S311 (see FIG. 11C).

  Step S307: The CPU 121 determines whether or not the sum of distance flags corresponding to a plurality of distances is larger than the sum (target value) quantized by the first method.

  If it is determined that the character is large (Yes), it is determined that the reference point cannot be adjusted so as to output a character smaller than the current value, and the process proceeds to step S308. If it is determined that it is not large (No), the process proceeds to step S319 (see FIG. 11C).

  If the total of the distance flags is larger than the target value, the character will be crushed and the visibility will be worse when the character is displayed if the distance between the reference points is further reduced. By abandoning the adjustment to be shortened and checking the presence or absence of the omission flag as another method, the possibility of further adjustment between reference points is investigated. The omission flag indicates whether or not the width of the distance to be adjusted can be set to “0” when the reference points along the specific axis (X axis, Y axis) are adjusted by grid fitting. Further, the value of the omission flag indicates the order in which the width of the distance to be adjusted is “0” when the width of the distance to be adjusted can be “0”.

  The distance flag indicates whether or not the distance flag has a minimum required distance width as a distance width between reference points along a specific axis (X axis and Y axis). Furthermore, the distance flag indicates the minimum distance required as the distance between the reference points. The distance flag is information for ensuring visibility when displaying the scaled character, and indicates the minimum distance width at which the character is not crushed. The distance flag is previously assigned to the character information before scaling (see FIGS. 4 and 7).

  Step S308: The CPU 121 determines whether or not an omission flag is set. In addition, since the adjustment between the reference points of the present invention can be performed only once, the adjustment between the reference points is not further performed between the already adjusted reference points, and the confirmation of the omission flag is unnecessary.

  When the omission flag is set between the reference points that have not been adjusted yet, it is necessary to treat the width of the distance between the corresponding reference points as “0” so that there is no apparent reference point. Therefore, if it is determined that the omission flag is set (Yes), the process proceeds to step S309.

  When the omission flag is not set between the reference points that have not been adjusted yet, there is no interval between the reference points to be omitted, and the total of the quantized distance widths cannot be adjusted to be smaller than the target value. Therefore, if it is determined that the omission flag is not raised (No), the process proceeds to step S330.

  Step S330: The CPU 121 ends the grid fitting process by quantizing the coordinate data of the scaled strokes by rounding off.

  Step S309: The CPU 121 sets the distance of the omission flag distance to “0” in order from the omission flag having the highest rank among the omission flags corresponding to the distance between the reference points that have not been adjusted yet. Here, setting the width of the distance of the omission flag to “0” means setting the value between the reference points after quantization to “0”, not operating the omission flag. By setting the distance width of the omission flag to “0”, it is possible to visually adjust the distance between the reference points determined to be omissible to “0”.

  Since the distance width between the reference points is set to “0” by executing step S309, the value of the distance flag is also set to “0”. Therefore, when step S310 is executed, then step S305 and step S306 are executed, and then step S307 is executed, the total value of the distance flags becomes smaller than the target value. As a result, by executing step S309, the process can proceed to step S319 after step S307 (see FIG. 11B).

  Step S310: The CPU 121 sets an adjusted flag for the distance between the reference points whose distance flag value is set to “0”, as adjusted by the omission process (step S309). The process proceeds again to step S305.

  Since the omission flag has an omission order, it is necessary to perform omission processing while originally keeping the order. However, if the already adjusted flag is set, the omission processing between the reference points is omitted. The omission processing is not performed in order. However, this omission process is performed when the sum of the distance flag values is larger than the sum of the widths of the distances between the quantized reference points according to the determinations performed in steps S305, S306, and S307. With the exception omitted, the omission flag omission processing is performed in the order of omission flags.

  Next, step S319 to step S326 will be described with reference to FIG. The CPU 121 narrows the distance between the plurality of reference points obtained by the second method so that the total value of the distances of the plurality of reference points does not exceed the target value obtained by the first method. In order to adjust, steps S319 to S326 are executed.

  Step S319: The CPU 121 determines whether or not there is a distance between the reference points for rounding up the quantization error from among the distances between the reference points for which no adjusted flag is set, and rounding up the quantization error. If there is a distance between the reference points, the reference points that are the maximum round-up are extracted.

  If it is determined that there is (Yes), the process proceeds to step S320. When narrowing the distance between the reference points, the character display quality can be optimally adjusted by narrowing from the distance between the reference points where the quantization error changes greatly. Therefore, the adjustment starts between the reference points of the maximum raised width.

  If it is determined that there is no (No), the process proceeds to step 327 (see FIG. 11A). This is because if there is no distance between the reference points where the adjusted flag is not set, the reference points cannot be adjusted any more.

  Step S320: The CPU 121 extracts a group of distances between reference points that are the same as the reference points that are the maximum round-up width extracted by executing Step 319. When the same distance flag is assigned to the distance between multiple reference points, this is to adjust all the widths of the distances between the reference points where the same same distance flag stands out of the distances between multiple reference points. is there.

  Step S321: It is determined whether or not all the distance widths between the plurality of reference points included in the extracted group of the same distance flag are 1 or more than the value of the corresponding distance flag. This is because the width of the distance between a plurality of reference points included in the extracted group of the same distance flags cannot be made smaller than the value of the corresponding distance flag.

  If it is determined that the number is 1 or more (Yes), the process proceeds to step S322. If it is determined that the number is not 1 or more (No), the process proceeds to step S326.

  Step S326: The CPU 121 determines whether or not there is a distance between the reference points that cause the quantization error other than the group extracted in step S319, and determines whether there is a distance between the reference points that cause the quantization error. If there is a distance, the reference points that are the maximum round-up of quantization errors other than those that will be extracted by executing step S320 are extracted. This is because an adjustment candidate is searched from among other reference points.

  If it is determined that there is (Yes), the process proceeds to step S320. If it is determined that there is no (No), the process proceeds to step S308 (see FIG. 11A).

  Step S322: The CPU 121 decreases the value of the quantized distance between the extracted reference points by one.

  Step S323: The CPU 121 sets an adjusted flag corresponding to the adjusted distance between the reference points so that the adjusted reference points are not adjusted again.

  Step S324: The CPU 121 determines whether or not the same distance flag is set for the distance between the extracted reference points. If it is determined that it is set (Yes), the process proceeds to step S325. If it is determined that it has not been set (No), the process proceeds to step S305 (see FIG. 11A).

  Step S325: The CPU 121 determines whether or not there is a distance between reference points having the same same distance flag among the distances between reference points for which no adjusted flag is set.

  If it is determined that there is (Yes), the process proceeds to step S322. If it is determined that there is no (No), the process proceeds to step S305.

  The CPU 121 performs processing so that the widths of the distances between the reference points having the same distance flag are all reduced by 1 by repeating Steps S322 to S325. When this process is completed, the process proceeds to step S305 to determine whether or not adjustment between the next reference points is necessary.

  Next, step S311 to step S318 will be described with reference to FIG. The CPU 121 executes step S311 to step S318 to increase the distance between the reference points obtained by the second method, while the total value of the distance widths of the reference points is the target value obtained by the first method. Without exceeding, the distance between the plurality of reference points is adjusted so as to approach the minimum range.

  Step S311: The CPU 121 determines whether or not there is a distance between reference points from which the quantization error is reduced, among the distances between the reference points for which the adjusted flag is not set. If there is a distance between the reference points, the reference points that are the maximum reduction are extracted.

  If it is determined that there is (Yes), the process proceeds to step S312. When the space between the reference points is widened, the display quality of the characters can be adjusted optimally by widening from the space between the reference points where the quantization error is greatly changed. Therefore, the adjustment is started between the reference points of the maximum clearance width.

  If it is determined that there is no (No), the process proceeds to step 327 (see FIG. 11A). This is because if there is no distance between the reference points where the adjusted flag is not set, the reference points cannot be adjusted any more.

  Step S312: The CPU 121 extracts a group of distances between reference points that are the same as the reference points that are the maximum clearance width extracted by executing step S311. When the same distance flag is assigned to the distance between multiple reference points, this is to adjust all the widths of the distances between the reference points where the same same distance flag stands out of the distances between multiple reference points. is there.

  Step S313: It is determined whether or not the number of distances between the plurality of reference points included in the extracted group of the same distance flags is larger than the width to be expanded. It is necessary to increase the distance between the reference points having the same distance flag of the same value by 1 at the same time, and only the number of distances between the reference points having the same distance flag of the same value is set between the reference points. This is because the width may be increased by adjustment.

  If it is determined to be large (Yes), the process proceeds to step S318. If it is determined that the number is not large (No), the process proceeds to step S314.

  Step S318: The CPU 121 determines whether or not there is a range of distances between the reference points that reduce the quantization error other than the group extracted in step S312 and determines the reference point that reduces the quantization error. If there is a width of the distance between, the reference points between the reference points that are the maximum reduction of the quantization error other than the group that would be extracted by executing step S312 are extracted. This is because an adjustment candidate is searched from among other reference points.

  If it is determined that there is (Yes), the process proceeds to step S312. If it is determined that there is no (No), the process proceeds to step S327 (see FIG. 11A).

  Step S314: The CPU 121 increases the width value of the quantized distance between the extracted reference points by one.

  Step S315: The CPU 121 sets an adjusted flag corresponding to the adjusted distance between the reference points so that the adjusted reference points are not adjusted again.

  Step S316: The CPU 121 determines whether or not the same distance flag is set for the distance between the extracted reference points. If it is determined that it is set (Yes), the process proceeds to step S317. If it is determined that it has not been set (No), the process proceeds to step S305 (see FIG. 11A).

  Step S317: The CPU 121 determines whether or not there is a distance between reference points having the same distance flag among the distances between reference points for which no adjusted flag is set.

  If it is determined that there is (Yes), the process proceeds to step S314. If it is determined that there is no (No), the process proceeds to step S305.

  The CPU 121 performs processing so that all the widths of the distances between the reference points having the same distance flag are increased by 1 by repeating Steps S314 to S317. When this process is completed, the process proceeds to step S305 to determine whether or not adjustment between the next reference points is necessary.

  With reference to Fig.11 (a), step S327-step S329 are demonstrated.

  Step S327: The CPU 121 determines the maximum coordinate value and the minimum coordinate value of the blocks constituting the character. This is to determine which coordinate is used as a reference point after scaling the width of a character along a specific axis.

  Specifically, the quantization error resulting from rounding the maximum coordinate value of the scaled reference point is compared with the quantization error resulting from rounding the minimum coordinate value of the scaled reference point. The coordinate value of the block is determined based on the coordinate value of which is smaller. The size of the block constituting the character is the sum quantized by the first method.

  For example, if the quantization error resulting from rounding the maximum coordinate value of the scaled reference point is less than the quantization error resulting from rounding the minimum coordinate value of the scaled reference point, the scaled reference point The maximum coordinate value is the maximum coordinate value of the block. The minimum coordinate value of the block is a value obtained by subtracting the sum quantized by the first method, which is the size of the block constituting the character, from the maximum coordinate value of the block.

  For example, if the quantization error resulting from rounding the minimum coordinate value of the scaled reference point is less than the quantization error resulting from rounding the maximum coordinate value of the scaled reference point, the scaled reference point The minimum coordinate value is the minimum coordinate value of the block. The maximum coordinate value of the block is a value obtained by adding the sum quantized by the first method, which is the size of the block constituting the character, to the minimum coordinate value of the block.

  Therefore, if the quantization error resulting from rounding the maximum coordinate value of the scaled reference point is less than the quantization error resulting from rounding the minimum coordinate value of the scaled reference point, the quantized maximum coordinate The value is the reference coordinate value of the displayed character. In addition, if the quantization error resulting from rounding the minimum coordinate value of the scaled reference point is less than the quantization error resulting from rounding the maximum coordinate value of the scaled reference point, the quantized minimum coordinate The value is the reference coordinate value of the displayed character.

  Step S328: The CPU 121 determines the reference point after the grid fitting process based on the maximum coordinate value of the block constituting the character, the minimum coordinate value of the block constituting the character, and the distance quantized by the second method. Determine the coordinate values.

  Step S329: The CPU 121 determines coordinates other than the reference points of a plurality of strokes constituting the character.

  For example, the point after the grid fitting process is determined so that the value of distance a / distance b is closest to the value of distance A / distance B. Here, the point on the character before being scaled corresponding to the predetermined point to be determined is the difference between the first reference point and the second reference point adjacent to each other among the reference points before being scaled. between.

  Here, the distance A is a distance between the point on the character before being scaled and the first reference point. The distance B is the distance between the point on the character before being scaled and the second reference point. The distance a is a distance between the predetermined point determined and the first reference point after the grid fitting determined in S328. The distance b is a distance between the predetermined point determined and the second reference point after grid fitting determined in S328.

  Hereinafter, a specific example of the grid fitting process procedure will be described with reference to FIGS. 11 and 12A.

  Step S302: The CPU 121 adds the widths of the distance X1 to the distance X5 (“2.00”, “3.44”, “1.94”, “3.50”, and “2.00”), and the added value A target value “13” is obtained by quantizing “12.88” by rounding off.

  Step S303: The CPU 121 quantizes each width of the distance between the plurality of scaled reference points by rounding off. Considering that the distance flag “1” is assigned corresponding to the distance X1 to the distance X5 (see FIG. 4A), the width of the distance after quantization is “2”, “3”, “2”, “4” and “2”.

To do. Here, it determines with (Yes) and a process progresses to step S312.

  Step S303: The CPU 121 quantizes each width of the distance between the plurality of scaled reference points by rounding off.

For example, the user may download the character display program 141 from a specific website on the Internet for a fee or free of charge, and install the downloaded program in the character display device 100. When the character display program 141 is recorded on a computer-readable recording medium such as a flexible disk, CD-ROM, or DVD-ROM, the character display program 141 may be installed in the computer using an input device. Good. The installed program is stored in the auxiliary storage device 140.

  Furthermore, for example, in the above-described embodiment, the case where characters are scaled and the scaled characters are displayed has been described as an example, but the present invention is not limited to this. The present invention can also be applied to a case where a graphic is scaled instead of or in addition to a character and the scaled graphic is displayed. In this case, a graphic display program is used instead of the character display program 141 or in addition to the character display program 141, and graphic data is used instead of the character data 142 or in addition to the character data 142. That's fine. The graphic display program can also include the same steps as the character display program 141. Like character data, graphic data can also include at least one reference point.

  The “characters” used in the present specification include, for example, hiragana, katakana, kanji, alphabets, pictograms, and numbers. Furthermore, “graphics” used in the present specification includes, for example, a part of characters, a pattern, and a symbol.

  As described with reference to FIGS. 4 and 7, the distance to which the same distance flag is assigned is determined in advance and is included in the data between the reference points, but the distance to which the same distance flag is assigned is determined in advance. It is not limited to being decided. Allocation of the same distance flag can be realized by executing the same distance flag acquisition program 141d.

  FIG. 18 shows the same distance flag acquisition processing procedure of the present invention. The same distance flag acquisition processing procedure is realized by the CPU 121 executing the same distance flag acquisition program 141d.

  FIG. 19 is a diagram for explaining a procedure for assigning the same distance flag to the data between reference points included in the character data 142 of the character “Crystal” shown in FIG.

  “Distance” also indicates the width in the X-axis direction between the reference points. This distance is the distance before being scaled. For example, the width of the distance X1 in the X-axis direction is “16”.

  Hereinafter, the same distance flag acquisition processing procedure of the present invention will be described with reference to FIGS.

  Step S401: An initial value “1” is set for the distance “i”, and an initial value “N” is set for the number of target distances “n”. For example, when the target distance is the distance X1 to the distance X11, n = 11.

  Step S402: It is determined whether or not the same distance flag is already attached to the distance “i”. This is because the same distance flag already assigned is excluded. If it is determined (Yes), the process proceeds to step S411. If it is determined that it is not attached (No), the process proceeds to step S403.

  Step S403: An initial value “i + 1” is set to the distance “j”.

  Step S404: It is determined whether or not the same distance flag is already attached to the distance j. This is because the same distance flag already assigned is excluded.

  Step S405: It is determined whether or not the difference between the width of the distance i and the width of the distance j is equal to or smaller than a predetermined magnitude “α”. If it is determined that the predetermined size is “α” or less (Yes), the process proceeds to step S406. If it is determined that the predetermined size is not less than “α” (No), the process proceeds to step S407. In the embodiment of the present invention, α = 1.

  Step S406: The distance j is set as a candidate for attaching the same distance flag.

  Step S407: “j” is incremented (“j + 1” is substituted for “j”).

  Step S408: It is determined whether or not “j” is larger than the target distance number “N”. If it is determined that the value is large (Yes), the process proceeds to step S409. If it is determined that it is not large (No), the process proceeds to step S404.

  Step S409: It is determined whether or not a candidate for attaching the same distance flag has already been set. If it is determined that a candidate has already been set (Yes), the process proceeds to step S410. If it is determined that no candidate is set (No), the process proceeds to step S411.

  By repeating steps S404 to S409, if i = 1 (distance X1 is a reference), distance X1, distance X3, distance X5, distance X7, distance X9, distance X11 are candidates for attaching the same distance flag. Is set. When i = 2 (distance X2 is a reference), distance X2 and distance X10 are set as candidates for attaching the same distance flag. When i = 4 (distance X4 is the reference), distance X4 and distance X8 are set as candidates for attaching the same distance flag. When i = 6 (distance X6 is a reference), only the distance X6 is set because there are no other candidates for attaching the same distance flag.

  In the description with reference to FIG. 19, if the predetermined size is “3”, the difference between the distance X2 having the width “7” and the distance X10 having the width “8” is 1, and thus the same. The same distance flag of the value is assigned.

  Step S410: The same distance flag having the same value is assigned. Values are used in order from 1.

  The same distance flag having the value “1” is assigned to the distance X1, the distance X3, the distance X5, the distance X7, the distance X9, and the distance X11. The same distance flag having the value “2” is assigned to the distance X2 and the distance X10. The same distance flag having the value “3” is assigned to the distance X4 and the distance X8. In this manner, even a plurality of distances originally including different sizes can be grouped as a group adjusted to the same size by assigning the same distance flag having the same value.

  Step S411: “i” is incremented (“i + 1” is substituted for “i”).

  Step S412: It is determined whether or not “i” is equal to the target distance number “N”. If it is determined that they are the same (Yes), the process ends. If it is determined that they are not the same (No), the process proceeds to step S402.

As described with reference to FIGS. 18 and 19, according to the same distance flag acquisition program of the present invention, the same distance flag between the scaled reference points is determined and the same distance flag is determined. Can be assigned.
In the present invention, the same distance acquisition program is executed when the same distance flag is not set in advance in the character data (142) shown in FIG. 1, and so on. Step S101 described with reference to FIG. Is executed after reading the data, and after acquiring the same distance flag by executing the same distance acquisition program, the scaling is performed by executing step S102. Enables the use of distance flags.
