Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to a practical character and turn generator that can easily generate character patterns with variable sizes.

[Technical background of the invention and its problems]

In recent years, text processing using computers has been widely used, and there is a strong desire for high quality hard copy output. and,
It is also desired that the thickness of characters output in hard copies can be set in various ways depending on the specifications.

However, in conventional computer systems, character hard copy output is performed by reading out pre-registered character patterns according to their character codes and printing them as a dot matrix. Character no (
It was very difficult to change the thickness of the turns. For this reason, the number of choices of font size, such as double-width or half-width, was limited.

Conventionally, in order to make it possible to output characters and patterns of various sizes, it has been possible to create character patterns of various lengths through computational processing by parameterizing the character font and expressing it mathematically. is considered. As a typical example, Knuth's Metafont method is known. However, in all of these character pattern generation methods, it is difficult to create the character pattern that is the basis of the Japanese character pattern, and the pattern data is expressed using a complex parameter, so it is difficult to generate characters. It took a huge amount of time to process the calculations. In addition, although it is theoretically possible to generate character patterns of various sizes, the control and processing for changing the size of character patterns is complicated, which poses a major problem in terms of usability. was there.

[Purpose of the invention]

The present invention has been made in consideration of these circumstances, and its purpose is to provide a highly practical character/base turn generator that can easily and efficiently generate four turns of characters of various sizes. Our goal is to provide the following.

[Summary of the invention]

In the present invention, a character pattern is expressed as position information of a plurality of representative points of the stroke and stroke thickness information at each of the upper h11 representative points and stored in a storage device, and the representative point is expressed from the position information of each representative point. In addition to determining the stroke data between the strokes, the outline data of the character/f-turn indicated by the stroke is determined based on the thickness information of the representative point.

In addition, if necessary, in addition to the position information and thickness information of each representative point, intelligence information of the character/lean can be provided, so that additional characters such as so-called tsukidashi, scales, serifs, etc. It also gives you a turn.

〔Effect of the invention〕

Thus, according to the present invention, since a character pattern is given by the position information and thickness information of the representative points of the stroke, the data format is very simple and easy to handle. Shigamo f+41 easy process 1! Since the outline information of a character pattern can be obtained from the information of a plurality of representative points, it is highly practical in terms of processability. Furthermore, since the character no f-turn is generated through the processing as described above, variable control of its size and its processing are simple, and the needs of 4Φ can be effectively met. Therefore, its practicality is a sieve.
A tremendous effect can be achieved.

[Embodiments of the invention]

Hereinafter, one embodiment of the present invention will be described with reference to the drawings.

11 is a schematic configuration diagram of the embodiment device, and 1 is a character and turn storage device that stores character pattern data of the number 11. For example, as shown in FIG.
~, each position information (x, y) of f and its thickness information (Z)
is given as four basic parameters. However, here, the above thickness information is given as a more detailed parameter, the line width on the right side in the direction of stroke progression at the representative point (0), and the line width on the left side as 0, and in addition to this, The saturation information (to) of the representative point is also given.However, the data of the representative point of the character pattern indicated by this information can be obtained by adding, for example, its format information (illustrated in Figure 3). The IK is registered on the storage device in the format as shown.The following table is an example of data showing the character pattern ")" shown in FIG.

Table 1 Note that here, the size of the character pattern frame is (X=10
00. Y=1000), Tsuma, Su(100OX
1000) is given as the thickness of a dot, and the position of each representative point is shown as a relative position within the above frame. Also, the format code (g) is (00
00) is the starting point of the character pattern stroke, (000
1) is the middle part of the stroke, and (0002)
indicates the end point of the stroke, and
Format codes such as intersections are used.

In addition, the code ('oooi) for the -6 gender information (g) indicates that it is the "starting point" part of the required character/gutaan, and other attribute information includes "scales" and "a Codes indicating attributes such as "shi", "serif", and "cologne" are given.

The character pattern data registered in the storage device 1 in this manner is read out from the storage device 1 according to the character designation, and is applied to the arithmetic unit 2. This performance section 2 has character and turn output specifications set in registers 3, 4.5, respectively, that is, vertical dimensions GX, 1X. Upon receiving each data of the character line GY and the character line 41 Hatake GW, the character pattern data is subjected to reduction/enlargement processing. In other words, as mentioned above, the character/mother turn data has the length of the frame (1o
oox 1ooo) is registered as a dot. On the other hand, if the output character pattern is to be displayed and output in the size of (32×32) dots, the value "32" is set in each of the GXX register and the GY register 4. In addition, if the line width of the character pattern to be output with this (32x32) dot size is set to a general standard, the value "32" is also set in the GW register 5. ) In the dot display, if it is desired to make the displayed character pattern thick, r48J empty data is set in the GW register 5, and if it is desired to be made thin, a value such as "24" is set. In accordance with the data set in the registers 3, 4.5, the character pattern data read from the storage device 1 is subjected to an agglutination process to set its size.

The supplement 1 section 6 receives the output from the calculation section 2 and calculates the position of each point of the stroke connecting each representative point based on the position information of the representative point of the stroke, for example, using the spline compensation 1 method or parabola mixing method. It is calculated according to the algorithm of the law etc. Then, the bit stroke generation unit 7 obtains the outline of the character/turn from the thickness information of each point of these strokes, and the output pattern panzer memory 8 contains the outline of the character/turn surrounded by the upper cone line. Area data is now stored as a character pattern.

That is, when the character pattern data shown in FIG. 2 and Table 1 is obtained from the storage device 1 and output as (32×32) dots or turns, the calculation section 2 performs the control shown in FIG. 4. According to the flow, the position ox, oy and thickness information OZ of each representative point of output character i4 turn are obtained.
Calculate OU. The position coordinates ox and oy of the representative point in the output coordinate system are calculated according to the number of dots of the pick, output character, and turn. After that, the attribute information is determined, and it is determined whether it is a decorative character pattern part such as the above-mentioned "tsukidashi" or "scale", and if it is not a decorative part, the line width is calculated as OZ, OU. ! +, (shi, The thin width is changed depending on the size of the character pattern. Also, when the representative point is a decorative part such as the above-mentioned "1" or "scale", the line width is calculated as , corrections are made to prevent the decorative part from becoming unintentionally larger or smaller.This process is performed on the data of all representative points of the character pattern.The table below shows the needle legs. This is the result.

Table 2 The interpolation unit 6 calculates each stroke point between each representative point from the position information shown in Table 2 above according to an algorithm such as spline interpolation, and reproduces the cyst lobe based on this. The following table selectively shows partial data of the stroke obtained in this way. Based on this position information, the stroke B in Fig. 2 can be calculated.
After obtaining the third representation, the outline data of the character pattern is obtained from such data as follows. That is, the i-th point on the interpolated stroke B is Pi,
Let the contour point on the right side of the stroke progress direction be PRi, and the contour point on the left side be PLi. At this time, when L=XN-+-XiM=Yi++-Yi is defined, the right contour point PRi is obtained as PRl=(XRi, YRi)yRt=yt-zt*-. Similarly, the left contour point PLi is set as PLl = (XL amount, YLi), XL amount = X i + U l *
-YLi=Yi-Ul*-. Contour point P obtained in this way
The connection 9 between Ri and PLi represents the outline of the output character/gutern. By filling the inside of the pattern indicated by this outline with, for example, dots, the character pattern is expressed by a dot matrix. Figures 5(a) and (b) show examples of this, and the pattern shown in Figure 2 is (32X3
2) Figures 5 (,) are output as dots, and Figure 5 (b) is output with thicker lines. This Fig. 5(b) shows that in order to make the character line width thicker, the size of the (32 x 32) dots is 9 degrees.
This shows an example in which "48" is set as the GW data. As is clear from this example, the lance at the "starting" part of the character pattern has been corrected so that it is unified regardless of the thickness of the character.

In this way, according to the present device, characters and base turns of a desired size can be generated by very simple processing. Moreover, since the character pattern data can be given as representative points of the stroke, it is very easy to create the original data. Further, in this case, a character pattern can be generated that takes into account the so-called stiffness of the brush, and the control parameters do not become complicated as in the conventional method. Therefore,
Its practical advantages are enormous.

In addition, since the processing is simple and the processing speed can be increased, it can be used as a hard copy device for various computer systems.

Note that if the line width is symmetrical with respect to the stroke line, such as in hiragana, the thickness information may simply be given as (2)). FIG. 6 shows an example of a character pattern obtained in this manner, and no inconvenience will occur. Further, by using the configuration 5, it is possible to simplify the data structure to be registered in the storage device '1. Furthermore, for character patterns for which so-called bottom alignment is desired, the purpose can be easily achieved by setting the bottom line width to "0" as shown in FIG. It is not limited to the examples. For example, it is of course possible to change the aspect ratio of the output character pattern. Furthermore, it goes without saying that the type of character pattern is not particularly limited, such as Chinese characters, numbers, and alphabetic characters.

However, the present invention can be implemented with various modifications without departing from the gist thereof.
