Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a character pattern generating device that outputs characters to a graphic output device such as a printer, plotter, or display.

BACKGROUND OF THE INVENTION In recent years, character pattern generating devices have been developed with the aim of generating not only characters in the conventional typeface but also high-quality and natural character patterns. Particularly in the field of Japanese output, research into outputting in calligraphy, which has traditionally been used to express characters, has progressed, and now there is development that not only outputs individual characters in calligraphy, but also outputs continuous characters. It is being done.

Hereinafter, an example of the above-mentioned current continuous character pattern generation device will be described with reference to the drawings.

FIG. 8 is a block diagram of the apparatus mentioned here as an example. 8.1 is a character string input section that reads a character code string;
2 is a character string storage unit that temporarily stores the input character string. 8.3 is a glyph information storage unit that stores glyph data (starting stroke/road surface type of each character, deformed parts of the starting stroke/road surface, coordinates of several representative points on the character skeleton line and their (thickness at a point) is memorized. 8.4 is a glyph information input section, which inputs the glyph information corresponding to the input character string from 8.3, and inputs the start image/road surface type to the initial image/road surface type temporary storage section of 8.6. The starting image/road surface deformation part information is stored in the deformation part temporary storage section, and the glyph data is stored in the 8 and 7 glyph data temporary storage sections, respectively.

8.8 is a continuation character judgment dictionary, which memorizes the continuation character type based on the combination of the cypress road surface type of the first character and the starting stroke type of the second character of two adjacent characters, and the continuation character type of 8.9. While searching for 8.8, the character determining section determines the type of continuation character for the two characters before and after the input character string in order from the beginning, and stores it in the continuation character type temporary storage section of 8.10. In the 8.11 index character synthesis section, 8.10.8.
Referring to 6.8.T, modify and synthesize the glyph data according to the predetermined procedure for each type of continuous glyph, and update the contents of 8.7. 8.12 is a character pattern generation unit that fleshes out the glyph data stored in 8.7 and generates a character pattern in the form of a dot pattern or a list of outline dots. Store in temporary storage.

The output display section 8.14 outputs and displays the character pattern on a graphic output device such as a display or a dot printer.

The operation of the character pattern generating device configured as described above will be explained below.

First, the character string input in 8.1 is stored in 8.2, and the glyph information corresponding to the character string is input from 8.3 to 8.4. The data structure of 8.3 is shown in FIG. The starting image/road surface type is a classification of these types based on the characteristics of their shape and position.The starting image/road surface deformation part is the point at which deformation ends at the initial image or the point at which deformation begins on the road surface when continuous characters are used. It represents. In 8.4, the first stroke and
The road surface type is stored in 8.5, the start image and long deformed parts are stored in 8.6, and the glyph shape data is stored in 8.7. In 8.9, the starting image and road surface type are referred to for all the spaces between two characters before and after the input character string, and while searching 8.8, the continuation character type is determined and stored in 8.10. FIG. 10 shows a flowchart of this determination.

In 8.11, according to the type of continuous character determined in 8.9, the glyph data is modified in accordance with the procedure predetermined for each type of continuous character, and the contents of 8.7 are updated. In 8.12, the new glyph data is fleshed out, character turn data is generated in the form of a binary dot pattern, a glyph dot sequence list, etc., and is stored in 8.13. Finally, in step 7.14, display the output on a printer or display.

Problems to be Solved by the Invention However, with the above configuration, it is necessary to determine the continuous character type of the two preceding and following characters for the entire input character string each time, and to correct the character shape data, which increases the amount of calculation. In view of the above-mentioned problems, the present invention can be applied to computers with low computing power, and the processing time is long. To provide a character pattern generating device which is fast to a certain extent.0 Means for Solving the Problems In order to solve the above problems, the character pattern generating device of the present invention consists in advance of data for parts to be continuous characters. The device is equipped with a continuation character parts storage unit, a continuation character parts dictionary that stores the type of continuation character parts, and a continuation character specification part that specifies a part to be a continuation character while referring to the continuation character parts dictionary. It is.

It is possible to quickly generate character patterns.

Embodiment A character pattern generating device which is an embodiment of the present invention will be described below with reference to FIG. FIG. 1 shows a block diagram of a character pattern generating device in a first embodiment of the present invention. In FIG. 1, 1.1 is a character string input section that reads a character string from an external device such as a keyboard or scanner. The glyph information processing unit 1.2 is a continuation character specifying unit 1.2.
a and a glyph information input section 1.2b. In 1.2a, refer to the continuation character part dictionary 1.3 and specify the part to be made into a continuation character and what kind of combination of continuation character parts will be used to make that part into a continuation character. means the data needed to generate a stroke for the part to be a continuation character, which is necessary when generating a continuation character. In the next step 1.2b, data is read from the glyph information storage units 1 and 4 for parts that are not to be continuous characters, and data is read from the continuous character part storage unit 1.6 for parts that are to be continuous characters. Based on the data read in step 1.2b, a character pattern is generated in the continuous character synthesis section 1.8, and the output display section 1.7 outputs a character pattern to the graphic output device. The operation of the character pattern generating device will be described below with reference to the drawings.

First, details of the information stored in 1.3, 1.4, and 1.5 will be described. 1.4 contains the glyph data of each character (the number of strokes, the coordinates of the representative point including the start and end points of each stroke, and the thickness of the stroke at that point) as shown in Figure 2a.
In 01.5, where 01.5 is stored, similar data in the form of two or more consecutive characters is stored as shown in Figure 3. Each continuation character component (hereinafter abbreviated as component) is given data indicating the characters that make up the continuation character, and the data corresponding to this is stored in 1.4. I will explain about it. Regarding the character string input in 1.1, in 1.2a, refer to 1.3 and decide which part to use for continuous characters and which parts to use for continuous characters, following the flow shown in Figure 4. and send that information to 1.2b.

In 1.2b, glyph data is read from 1.4 for parts that are not to be continuous characters, and component data is read from 1.5 for parts that are to be continuous characters. 1.6 is 1.2
Generate a character pattern from the data read in step b as shown in Figure 6 (here we describe the method for generating one stroke, but since each character and part is a collection of strokes, the generation process The principle is the same). First, a 9th order spline curve is obtained in which the skeleton line passes through the representative points of each stroke (FIG. 5A).

Next, the contour points are calculated from the information on the slope and thickness of the skeleton line at each point (Fig. 6), and the contour line is obtained by interpolation with a cubic spline curve (Fig. 5). However, the outlines of the starting and ending points of the stroke are determined based on the shape of the writing surface, which has been given data in advance. Figure 6-2 shows the final result of stroke generation.

The character pattern data thus generated is sent to 1.7 and output to a graphic output device such as a printer or display. Note that it is also possible to have the character shape data of 1.4 and 1.5 as a drato-no-ku turn.

As described above, in this embodiment, the continuation part storage unit 1.
By having the data of 6 in correspondence with the continuation character part dictionary 1.3, the continuation character specification section 1.2a can specify parts to be continuation characters and parts not to be continuation characters, and the former can be specified in 1. 5, the latter can generate character patterns by directly using the data read from 1.4.

A second embodiment of the present invention will be described below with reference to the drawings. Since the overall configuration is the same as that of the first embodiment, FIG. 1 also serves as a configuration diagram of the second embodiment. 1st
The differences from the embodiments 1.4 and 1.6 are the data structures of 1.4 and 1.6 and the corresponding processing in the glyph information input section 1.2b.

The details will be described below. The data structure of 1.4 is shown in Figure 2, and the data structure of the continuation part storage part 1.6 is shown in Figure 3. The difference from the first embodiment is that information on the starting stroke of each character and deformed point on the road surface is added to the data in the glyph information storage unit 1.4, and data in the continuous character parts storage unit 1.6 is added to the data in the glyph information storage unit 1.4 for each continuous character. From the deformed point of the final stroke of the first character of the part,
This point is the data up to the deformed point of the first stroke of the final character. Therefore, the glyph information input section 1.2
In b, read the data from 1.4 to the deformed point of the last stroke of the first character in the part where the continuation character is specified,
From there, read the specified continuation character part and change the data to 1.4 again from the deformed point of the first stroke of the final character.
Load from.

The operations other than those described above are the same as in the first embodiment. In this case as well, the 1.4 and 1.6 character shape data can be provided as a dot pattern.

In addition to the effects of the first embodiment, the second embodiment has the following advantages:
．． By making the data structures of 4 and 1.6 as described above, it is possible to obtain the effect of increasing the amount of information that can be stored in 1.6.

Finally, a third embodiment of the present invention will be described with reference to the drawings. Since the configuration of the third embodiment is similar to that of the first embodiment, FIG. 1 also serves as a configuration diagram of the third embodiment.

Below cylinder 1. Points different from the second embodiment will be listed.

The data in 1.4 has a data structure similar to that of the second embodiment shown in Figure 2, but since the continuation character part in this example is a part that connects two characters, the continuation character part The data structure of the storage section 1.5 is as shown in FIG. Therefore, the dictionary in the glyph information storage section 1.4 is a dictionary of two characters that can be continued. 1.3 in 1.2a
While referring to , determine the part to be continued as shown in Figure 7, and enter that information into 1.2b. 1.2
In b, the data up to the deformed point of the last stroke of the first character of the two characters specified as a continuation character is read from 1.4, the specified continuation character part is read from there, and the data of the first character of the second character is read. Data is read from the glyph information storage unit 1.4 from the deformed point of the stroke. The operations other than those described above are the same as in the first embodiment. In this case as well, the glyph data in the glyph information storage section 1.4 and the continuous character parts storage section 1.5 can be stored as dot patterns.

In addition to the effects of the first embodiment, the third embodiment has a larger amount of data that can be held in the attached part storage section 1.6 than the previous two embodiments. This has the effect that the types of characters that can be made into tetsuzuki characters increases, and the data creation in the tsuzuki character part storage section 1.6 is easier than in the previous two examples.

Effects of the Invention The character pattern generation device of the present invention described above has a continuous character specification section, a continuous character parts dictionary, a continuous character parts storage section, and a character shape information storage section, so that it is possible to refer to the continuous character parts dictionary. While specifying the continuation character part in the continuation character specification field, the part to be continuation character is specified from the continuation character part dictionary,
For parts that are not to be continuous characters, continuous character patterns can be automatically generated by reading data from the glyph information storage section and generating a character pattern based on that data.
