Description

[Detailed description of the invention]

0001

[Industrial Application Field] The present invention enables characters displayed on the display section of a word processor to be enlarged or reduced in that direction by specifying the direction using a cursor movement key. The present invention relates to a character enlargement/reduction processing method that can be displayed on the display unit in real time.

0002

BACKGROUND OF THE INVENTION Currently, with the advancement of OA through the digitization of documents, word processors are used in various fields, not only in companies but also at home and at the individual level. Particularly in recent years, the expressions of the characters themselves have been diversifying even when it comes to document expressions. Examples of such expressions include the one shown in FIG. 11. In other words, in addition to standard shapes, there are shapes with patterns, borders, oblique angles, or rotation angles. On the other hand, the "size" of characters includes horizontal enlargement, vertical enlargement, vertical and horizontal enlargement (so-called 4 times enlargement, and generally N x M
In addition to (enlarged) characters, reduced characters are also used (though not shown). When creating such a font, the desired shape and size are obtained by instructions from the keyboard.

0003

[Problem to be solved by the invention] As mentioned above, it is possible to change the characters themselves, but if the shape and size of the characters do not take into account the balance within the document, it will only spoil the aesthetic appearance of the document. In extreme cases, it may reduce its value as an information transmission medium. It is recognized that the important factors for balance in the above are not only the shape of the letters but also the size.

[0004] In the above case, the most common way to set the font size is to specify the degree of enlargement or reduction using a magnification factor by inputting from the keyboard. Most of the time I use this method. However, when observing the manner in which characters whose size is specified to be enlarged or reduced by the magnification as described above are displayed on the display unit, the desired balance may not be achieved. In such a case, it is necessary to specify the magnification again and display the image again, and sometimes a subsequent operation is also required. This poses a problem in that document creation requires extra time and effort, leading to a decline in office efficiency. Furthermore, even if the user operates by changing the magnification as described above, the desired size of characters is not necessarily obtained, and there is also the problem that the user is forced to end the document creation.

The present invention solves the problems existing in the above-mentioned prior art, allows characters enlarged or reduced to a desired size to be placed in a document in a short time and in a well-balanced manner, and also allows characters to be placed in the document being created or The purpose of this invention is to provide a character enlargement/reduction processing method that allows character strings to be viewed in real time and to be modified on the display as necessary.

[0006]

[Means for Solving the Problems] In order to achieve the above object, a first invention provides a character generator, a keyboard, and an enlargement processing function and a reduction processing function that are selectively enabled by input from the keyboard. a processing device having a workpiece for storing processing results; and a display, the processing device is configured to enlarge or reduce characters of the character generator and display the results on the display, and the enlargement processing function and the reduction processing function each have a function of enlarging or reducing the character by at least 0.1 times by inputting from the keyboard.

[0007] Next, a second invention is characterized in that, in the first invention, the character string in the area designated by input from the keyboard can be moved in units of at least 0.1 times. It is something to do.

FIG. 1 is a diagram explaining the principle of the present invention. In FIG. 1, reference numeral 1 denotes a screen, which displays characters or character strings in a state before scaling processing. Reference numeral 2 denotes a processing device which incorporates at least an enlargement processing function 3 and a reduction processing function 4, and is provided with a keyboard 5 for operation to enable these functions. 6 is a screen, which displays characters or character strings after being enlarged/reduced. In order to simplify the explanation, the individual keys arranged on the keyboard 5 are not shown.

[0009]

[Operation] In FIG. 1, first, a character or character string to be enlarged or reduced is displayed on the screen 1 in advance. Next, a key on the keyboard 5 is pressed to enter a process for enlarging/reducing characters. Then specify the starting position of the string you want to enlarge or reduce. Use the → key (cursor right movement key) to specify the range of character strings on screen 1, and make that part clear by underlining or inverting it to make it easier to understand. At the end of the string range, use the execute key to end the range specification.

[0010] Next, the size of the character string is changed, that is, enlarged or reduced. In this case, this is done with the beginning of the character string as a reference. This character string is enlarged to the right with the → key, and reduced to the left with the ← key (cursor left movement key). Also, the ↑ key (cursor up key) reduces the size upward, and the ↓ key (cursor down key) zooms in the downward direction. At this time, the enlargement processing function 3 or the reduction processing function 4 built in the processing device 2 performs 0.
The image is enlarged or reduced by a factor of 1, and if each cursor movement key is pressed while holding down the CTRL key on the keyboard 5, the image is enlarged or reduced by a factor of 1. Note that the entire enlarged or reduced character string can be moved by pressing CTRL+SHIFT+each cursor movement key. After setting the character string to the desired size and position, press the end key to end the process. This result is displayed on screen 6.

[0011]

[Embodiment] FIGS. 2 to 5 are explanatory diagrams of the processing flow in embodiments of the present invention, and are "OASYS300A".
FIG. 3 is an explanatory diagram of processing when enlarging, reducing, and moving a character string. First, in FIG. 2(a), the enlargement/reduction function during editing is selected by pressing the enlargement/reduction key (all not shown) on the keyboard. Next, move the cursor to the beginning of the character string you want to enlarge or reduce and press the execution key (not shown) to confirm (marked with ■ in FIG. 2(b)). Move the cursor to the end position of the character string range and press the execution key to confirm the range (underlined and black mark in FIG. 2(c)).

As shown in FIG. 3(a), the range of the character string is clearly defined by the area indicated by the broken line, so the cursor movement key is used to enlarge or reduce the range. In this case, according to only the cursor movement keys, 0.1
The magnification changes by a factor of 1. If you press the CTRL key + the cursor movement key, the magnification changes by a factor of 1. In (a), since the CTRL key + → key is pressed, the image is enlarged by 1 times in the right direction, and as shown in (b), it is enlarged to a magnification of 1 vertically by 2 horizontally. Next, in (b), the character string is further enlarged by 1 times in the right direction by pressing the CTRL key + → key, and as shown in (c), a character string with a magnification of 1×3 horizontally can be obtained.

In FIG. 4, when the ← key is pressed as shown in (a), the character string is reduced by 0.1 times to the left, and as shown in (b), the character string is reduced to a magnification of 1 times vertically x 2.9 times horizontally. Then,
If you further press the ← key, the size will be reduced by 0.1 times to the left (c
), the magnification changes to 1 x 2.8. In this state, if you press the CTRL key + ↓ key, the image will be enlarged downward by 1 times, as shown in (d), 2.8 x 2.8 x 2.8 x 2.8
The string will be twice as large. If you press the ↑ key in (d), the image will be reduced by 0.1 times in the upward direction, resulting in a magnification of 1.9 vertically x 2.8 horizontally, as shown in (e). Since the balance of this character string is undesirable, in (e), press the ← key to reduce the size by 0.1 to the left, and as shown in (f), the character string has a magnification of 1.9 x 2.7. column. Next, in the layout of the entire document, the balance is not good at this position, so in (f), press SHIFT + CTRL + →
Press the key to move the character string to the right until it is in the position shown in (g). Through the above processing, a character string of the desired size is obtained at the desired position, so press the end key (not shown) to return to the original editing screen. FIG. 5 shows a part of the editing screen after the above processing.

FIGS. 6 and 7 are flowcharts showing embodiments of the present invention, and particularly relate to control of the main processing section. The flow of scaling and moving a character string will be explained using both figures. First, while editing a document, if you want to enlarge or reduce a character string, press the enlarge/reduce key (1
1). As a result, the scaling program is loaded onto the memory (12). Next, the scaling range of the character string is specified (13), and the specified character code is read from the screen and stored in the memory (14). Next, the size of the character is determined from the character code on the memory, and is set in the magnification storage area, and the upper left coordinates, which are the display reference for the character string, are set in the display start storage area (15). In this case, the magnification is 1 vertically
x Horizontal 1, and the display start position is X:50, Y:100.

Next, use only the cursor movement keys as input keys to scale up and down at a magnification of 0.1 times in each direction (16), or use the CTRL key together with the cursor movement keys to zoom in and out at a magnification of 1 times in the up, down, left and right directions (16). Scale by magnification (
When 17) is selected and executed, the character string currently displayed on the screen is erased and the character string with the updated magnification is redisplayed (18). If the displayed character string is not desired, the selection is made again and repeated. If a character string with the desired magnification is obtained, the process ends (21),
Return to the original editing process (23). Note that if the input key is canceled (22), the process also ends and the original editing process returns.

[0016] Even if the magnification of the character string is desired, if the display position is not desired, press the SHIFT key + CT
By selecting the RL key + cursor movement key, the coordinates of the display start position are moved in units of ±1 (19). In this case, the currently displayed character string is erased and the character string with the current magnification is displayed again at the updated display position (20).
The coordinates are moved until the entire document is balanced, and when the end key is pressed (21), the process ends and the original editing process returns (23).

Next, FIG. 8 is an explanatory diagram showing a character string display section in an embodiment of the present invention. In FIG. 8, when scaling a character string, the starting position (dot) of each character in the character string is first determined. In other words, the first character (for example, "O") is determined by the coordinates X and Y of the display start position.The second and subsequent characters are determined by the character spacing d from the first or previous character.In this case, the character spacing d is the character spacing specification value for standard characters x horizontal magnification.

FIG. 9 is a flowchart showing character enlargement/reduction processing in an embodiment of the present invention. When enlarging or reducing a character string, each character is processed one by one. For example, when enlarging "O", first the corresponding character is The vector data is searched (31), and the length of the vector is expanded or reduced (32). Next, if the magnification is very large (33), smoothing processing is performed as described below (34). That is, in small characters, the curves created by the combination of straight lines are not noticeable, but in large characters, the straight parts are noticeable, so supplementary correction of the vectors is performed to make them less noticeable. When the smoothing process is completed, CALL the screen display section to display (35),
End (36).

FIG. 10 is an explanatory diagram showing an example of smoothing processing. In FIG. 10, ■■■ are vectors. That is, as shown in (a) and (b), the vectors ■■ have the same intersection angle but different lengths. Therefore (a)
In the case of small characters as shown in (b), the combination of vectors ■■ is not noticeable, but in the case of large characters as shown in (b), the intersection of the combinations of vectors ■■ becomes noticeable, and such a combination If a curved line is formed, it not only significantly impairs the aesthetic appearance, but also causes misunderstanding or confusion with other characters. Therefore, as shown in (c), the start and end points of the vector ■■ are left as they are and shortened, and the vector ■■ having an inclination intermediate between the inclination of the vector ■ and the inclination of the vector ■■ is supplemented. In this case, the length of vector ■ is determined from the length of another vector ■■ that has been cut short. However, during the above processing, it is necessary to judge whether or not the angle is suitable for smoothing.

FIG. 12 is a block diagram showing an embodiment of the present invention. In FIG. 12, 40 is a memory, 50 is a processing device, and 70 is a display. Built into the memory 40 are a character generator 41, an enlargement program 42, a reduction program 43, and a rotation program 44 corresponding to each character. Next, the processing device 50 includes a workpiece 51, an image memory 52, an enlargement processing function 53, a reduction processing function 54, and a rotation processing function 55, as well as a keyboard 56 having keys for inputting to these functions.
is provided.

With the above configuration, when a character is specified using each key on the keyboard 56, the corresponding character is imported from the character generator 41 in the memory 40 via the bus 57 to the workpiece 51 via the bus 45. ，
So-called document creation is performed, and the results are stored in image memory 52 via bus 58 and further displayed on display 70 via bus 59.

Next, when the enlargement/reduction key 60 of the keyboard 56 is pressed, the enlargement program 42 and the reduction program 43 are transferred from the memory 40 to the processing device 50 via the buses 46 and 47, and the enlargement processing function 53 and reduction processing function are performed. Function 54 is enabled. In this state, if an instruction is given to the workpiece 51 by inputting the cursor movement key 61 or by using the CTRL key 62 in combination, processing corresponding to the instruction can be performed and the result can be displayed on the display 70. To simplify the explanation, for example, the character
If the standard character of the generator 41 is 6 x 8 dots, and it is enlarged to 8 x 10 dots in the workpiece 51 according to the instruction from the keyboard 56 of the processing device 50, as shown by the broken line, other input characters The characters, including the characters, pass through the image memory 52 and are displayed on the display 70 as enlarged characters of 8×10 dots.

As described above, necessary programs are loaded into the processing device 50 from the memory 40 in response to instructions from the keyboard 56, and the area in the workpiece 51 is used for processing such as enlarging and reducing character strings. The processing results can be displayed on the display 70 in real time.

In this embodiment, an example was described in which a character or character string is enlarged or reduced. By loading a program stored in memory into a processing device, it is possible to enlarge or reduce a character or character string. In addition to being able to perform angularization, rotation, and other processing,
Of course, it is possible to further enlarge, reduce, and move these states. Furthermore, the unit by which characters or character strings are enlarged or reduced is not limited to only 0.1 times.
Other magnifications can be selected as needed.

[0025]

[Effects of the Invention] Since the present invention has the configuration and operation as described above, it is possible to enlarge or reduce a character or character string to a desired size without being aware of the magnification, and moreover, while viewing it on a display. This has the effect of shortening the document creation time and making it possible to arrange the characters or character strings in a well-balanced manner in the document.
