Description

  The present invention relates to a method for generating a stroke, and more particularly, to a method for generating a stroke that is updated according to a set of strokes of thick type and a set of strokes of thin type.

  Today, kanji input methods are widely used. When generating a font, typically data is loaded from a font generator and then the font is generated according to the relevant parameters of the font.

は、５個のキーポイントＫ１乃至Ｋ５、４個の幅の値Ｗ１乃至Ｗ４を含む。幅の値は、それぞれ２つのキーポイントの間に設定される。例えば、キーポイントＫ２及びＫ３により形成される部分的ストロークの幅の値は、Ｗ２である。 The relevant parameters of the font include multiple keypoint and width values for each stroke. Please refer to FIG. FIG. 1 shows a number of stroke keypoints and width values. Stroke of kanji "convex" [outside 1]

Is shown in FIG. Stroke [Outside 2]

Includes five key points K1 to K5 and four width values W1 to W4. Each width value is set between two key points. For example, the value of the width of the partial stroke formed by the key points K2 and K3 is W2.

  However, in the conventional method, when a font having various widths is required, the design engineer or manufacturer has to design a new set of fonts. Furthermore, if the font width is adjusted by directly increasing or decreasing the font width value, the original structure of the font is degraded. In other words, the font structure looks like a wire, and some fonts cross the border. Therefore, the conventional method cannot generate various fonts without deteriorating the font structure unless the fonts are redesigned and repeatedly designed.

  A method for generating a stroke includes the step of reading coordinates and at least one width value of a plurality of key points of a thick stroke corresponding to a target stroke, and a step of reading a plurality of key points of a thin stroke corresponding to the target stroke. Reading coordinates and at least one width value, coordinates of the plurality of key points of the thick stroke and values of the at least one width, coordinates of the plurality of key points of the thin stroke, and the at least one Generating the target stroke according to a width value and at least one scaling ratio of the target stroke; and displaying the target stroke on a display.

  By using the method provided in the first embodiment in the fourth embodiment, the font width can be changed without degrading the structure of the font. Thus, when a new set of fonts needs to be generated, it is only necessary to generate a new set of fonts based on the original font, and there is no need to redesign the new font.

  These and other objects of the present invention will become apparent to those skilled in the art after reading the following detailed description of the preferred embodiment shown in the various drawings.

  Although some terms refer to specific elements in the specification and claims, it is noted that a manufacturer may use different terms to refer to the same element. However, the definition between elements is based on their function rather than their names. Further, in the specification and claims, the term “comprising” is broad and should not be considered “consisting of”.

  While embodiments and figures are provided below to describe the present invention in detail, it is noted that the scope of the present invention is not limited to the provided embodiments and figures.

FIG. 2 shows a flowchart of generating a target stroke according to the first embodiment of the present invention. The explanation is as follows.
Step 202: Read the coordinates and at least one width value of a plurality of key points of the thick stroke corresponding to the target stroke.
Step 204: Read the coordinates and the value of at least one width of the plurality of key points of the thin stroke corresponding to the target stroke.
Step 206: According to the coordinates and at least one width value of the plurality of key points of the thick stroke, the coordinates and at least one width value of the plurality of key points of the thin stroke, and at least one scaling ratio of the target stroke. Generate the desired stroke.
Step 208: The target stroke is displayed on the display.

  Stroke width values include horizontal stroke, vertical stroke and tilt stroke width values. In step 204, the width value of at least one of the thin strokes represents the width value of the horizontal, vertical and inclined strokes of the thin stroke. Multiple key points and at least one width value of the thick stroke may be stored in a database in a memory of the computing device for reading. Further, the key points and at least one width value of the thick and thin strokes can be read according to the identification code of the target stroke, and each stroke of the font has its own identification code.

  In step 206, when generating the target stroke, in order to generate a plurality of key points of the target stroke, an intermediate value is estimated for the plurality of key points of the thin stroke and the plurality of key points of the thick stroke. (Interpolation) is executed. Also, in order to generate at least one width value for the target stroke, an interpolation of at least one width value for the thin stroke and at least one width value for the thick stroke is performed. Executed. The scaling ratio of the target stroke can be changed according to user settings to produce a wider or narrower target stroke. Furthermore, the horizontal stroke, vertical stroke, and inclined stroke of the target stroke can have the same scaling ratio or different scaling ratios, so that various fonts can be generated by replacement and combination without newly designing the font. . That is, a new font can be generated by individually setting the scaling ratio of the horizontal stroke, vertical stroke and slant stroke of the original font. This reduces the fonts that need to be stored in the database.

  In the conventional method, when the font is adjusted to be thicker or thinner, the key points of the font remain unchanged, so that the overall structure of the font is deteriorated. This makes the font look undesirable, and the deterioration of these structures causes neighboring Chinese characters to overlap each other. That is, the conventional method can only generate a new font by adjusting the overall width of the stroke, but cannot adjust each stroke individually.

  In step 206 of the present invention, intermediate value estimation is performed for the key points of the fine stroke and the key points of the thick stroke to generate the key points of the target stroke. Also, an intermediate value estimate is performed for at least one width value of the thin stroke and at least one width value of the thick stroke to generate at least one width value of the target stroke. . That is, the range of the generated target stroke keypoint and at least one width value is limited to between the thin stroke and thick stroke keypoint and at least one width value, so the generated target stroke The structure does not deteriorate and does not overlap with other strokes or characters. In step 208, the generated stroke can be displayed on a display device such as an LCD, projector, or node PC.

  In the first embodiment, the target stroke is generated by executing the estimation of the intermediate value with respect to the thin stroke and the thick stroke, but the method of generating the target stroke uses the estimation of the intermediate value. It is not limited to only. In other words, the estimation of the intermediate value performed in the first embodiment can be replaced with an arithmetic mean, a root mean square, and a weighted average, in particular. Any method that applies a combination of two different sets of fonts to produce the desired set of strokes is within the scope of the claims of the present invention.

FIG. 3 shows a flow chart of generating a target stroke according to the second embodiment of the present invention. The explanation is as follows.
Step 302: Read the coordinates and at least one width value of the plurality of key points of the thin stroke corresponding to the target stroke.
Step 304: Generate at least one width value of the thick stroke according to at least one width value of the thin stroke to form a thick stroke.
Step 306: The target stroke according to the coordinates and at least one width value of the plurality of key points of the thick stroke, the coordinates and at least one width value of the plurality of key points of the thin stroke, and at least one scaling ratio. Is generated.
Step 308: The target stroke is displayed on the display.

  The difference between the first embodiment and the second embodiment is that the method for generating a target stroke in the second embodiment starts by applying a thin stroke, and then a thick stroke. The point is to use fine strokes to generate. At step 304, a thick stroke key point is generated according to a thin stroke key point. For example, if the key point of the thick stroke is generated by reducing the key point position of the thin stroke to the inner position, the situation where the generated thick stroke exceeds the boundary of the character can be avoided. Further, the width value of the thick stroke is generated according to the width value of the thin stroke. For example, the corresponding thick font can be generated by adjusting the horizontal, vertical and slant strokes of the thin font with the same or different scaling ratios. After the thick stroke is generated, the intermediate value is estimated for the thin stroke and the thick stroke generated from the thin stroke, and the target stroke for which the intermediate value is estimated is generated. In step 308, the generated target stroke is displayed on the display.

FIG. 4 shows a flowchart of generating a target stroke according to the third embodiment of the present invention. The explanation is as follows.
Step 402: Read the coordinates and the value of at least one width of a plurality of key points of the thick stroke corresponding to the target stroke.
Step 404: Generate at least one width value of the thin stroke according to at least one width value of the thick stroke to form a thin stroke.
Step 406: The target stroke according to the coordinates and at least one width value of the key points of the thick stroke, the coordinates and at least one width value of the key points of the thin stroke, and at least one scaling ratio. Is generated.
Step 408: The target stroke is displayed on the display.

  The difference between the first embodiment and the third embodiment is that the method for generating a target stroke in the third embodiment starts by applying a thick stroke, and then a thin stroke. The point is to use a thick stroke to generate. At step 404, a thin stroke keypoint is generated according to the thick stroke keypoint. For example, the key point of the thin stroke can be generated by moving the position of the key point of the thick stroke outward to the outer position. However, the moved position must not cross the boundary. Further, the width value of the thin stroke is generated according to the width value of the thick stroke. For example, the corresponding flesh font can be generated by adjusting the horizontal, vertical and slant strokes of the flesh font with the same scaling ratio or different scaling ratios. After the thin stroke is generated, the intermediate value is estimated for the thick stroke and the thin stroke generated from the thick stroke, and the target stroke for which the intermediate value is estimated is generated. In step 408, the generated target stroke is displayed on the display.

FIG. 5 shows a flowchart of generating a target stroke according to the fourth embodiment of the present invention. The explanation is as follows.
Step 502: Read the coordinates of at least one width and at least one width value of a thick stroke corresponding to each target stroke of the target font.
Step 504: Read the coordinates of at least one width and the value of at least one width of the fine stroke corresponding to each of the target strokes of the target font.
Step 506: The target stroke according to the coordinates and at least one width value of the plurality of key points of the thick stroke, the coordinates and at least one width value of the plurality of key points of the thin stroke, and at least one scaling ratio. Generate each of
Step 508: Generate a target font according to the generated target stroke.
Step 510: Display the target stroke on the display.

  In the fourth embodiment, the generation of the target font is based on the step of generating the target stroke in the first embodiment. Therefore, by using the fourth embodiment, when various fonts are needed, a new font can be generated by individually setting the scaling ratio of the horizontal stroke, the vertical stroke and the slant stroke of the original font. This reduces the fonts that need to be stored in the database.

  Please refer to FIGS. 6A to 6C. 6A shows a thin stroke of the character “茅”, and FIG. 6B shows a thick stroke of the character “茅”. In FIGS. 6A and 6B, an intermediate value is estimated for the key point of the thin stroke and the key point of the thick stroke, and is also intermediate for the width value of the thin stroke and the width value of the thick stroke. Value estimation is performed, and the target fonts A1-A25 are generated. Since the key point and width values of the target font A1-A25 are generated by performing intermediate value estimation on the thin stroke of FIG. 6A and the thick stroke of FIG. 6B, the target font A1- The structure of A25 does not cross the boundary.

  FIG. 6C shows 25 exemplary purpose fonts A1-A25. In FIG. 6C, the horizontal, vertical and slant strokes of the target font A1-A25 may have different scaling ratios. For example, for the target fonts A1, A7, A13, A19, and A25 in FIG. 6C, the horizontal, vertical, and inclined stroke width values are increased simultaneously in the direction from A1 to A13, along A13, A19, and A25. You can see that With respect to the target fonts A1, A6, A11, A16 and A21 in FIG. 6C, the horizontal and inclined stroke width values increase simultaneously in the direction from A1 to A11 along A11, A16 and A21. It can be seen that the value of the width of the vertical stroke has not increased. For the target fonts A1, A2, A3, A4 and A5 in FIG. 6C, the vertical and slant stroke width values increase simultaneously in the direction from A1 to A3, A4, and A5 along A1. It can be seen that the value of the width of the horizontal stroke has not increased. Therefore, from FIGS. 6A-6C, the fourth embodiment of the present invention can set different scaling ratios for horizontal, vertical and inclined strokes, so that strokes of arbitrary width can be set without degrading the structure of the target font. It can be seen that the desired font is generated. Those of ordinary skill in the art who readily understand the present invention have shown only 25 target fonts, but the present invention is not limited to generating only 25 target fonts, and the present invention does not include more fonts. The horizontal, vertical and tilt strokes can be individually adjusted in various ways. Any application and combination of the method of generating strokes and fonts of the present invention is within the scope of the claims of the present invention.

  As described above, by using the method provided in the first embodiment in the fourth embodiment, the font width can be changed without degrading the font structure. Thus, when a new set of fonts is needed, it is only necessary to generate a new set of fonts based on the original font, and no redesign is required.

  Those skilled in the art will immediately recognize many variations and alternatives to the apparatus and method while adhering to the teachings of the present invention. Accordingly, the above disclosure should be construed as limited only by the metes and bounds of the appended claims.
