Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a character generation method, particularly a character generation method for arbitrarily changing the size of characters in handheld word processors, so-called character fonts. Concerning improvements to the generator.

[Conventional technology]

Conventionally, as a character generation method for arbitrarily changing the character size as described above, the yr! ! The method was as shown in J. In other words, Figure 1 is a conceptual diagram showing the conventional method of character generation. For example, the outline of the kanji character ``stone'' was captured as vector data, and characters were enlarged or reduced based on that data. It is something.

[Problem that the invention seeks to solve]

However, the conventional character generation method described above, namely 1
When character outlines are treated as vector data and the size of the characters is changed, a large amount of time is spent filling in the inner part surrounded by the vector data, which slows down document creation. There was a problem with it being stored away.

Therefore, the present invention has been made by focusing on the problems of the related art. The purpose is to provide a character generation method that can be applied to electronic publishing systems.

[Means for Solving the Problems] In order to achieve this purpose, the sentence generation method according to the present invention is characterized by capturing one character as vector data in the scanning direction.

[Effect]

As mentioned above, by considering characters as vector data in the scan direction, especially in the raster direction, "0" -
By constructing characters with a count of "1" and adding simple calculations, characters can be generated without the need to fill in the parts that constitute one character, that is, the size of the characters can be changed, which is useful for document creation. The speed will be significantly increased.

〔Example〕

Next, an example of the implementation of the present invention will be explained in detail with reference to FIGS.

FIG. 1 is a conceptual diagram showing the character generation method according to the present invention. According to the character generation method according to the present invention, for example, in the same way as in the conventional example, the kanji character "stone" 1 is moved in one raster direction. It is assumed that the vector data 2, 2, etc. For example, if you look at the 16x16 display conceptual diagram shown in Figure 2, the white part is "0" and the one character part is "1". Here, each vector data 2.2. The configuration of ... is that the first line is all "0" and F, and from the second to fourth rows, rQJ is 4, "l" is 9, and "0" is 2 again, Since the character part is diagonal in the system t,), the number of "1"s in the character part remains unchanged at 3, and the number of "0"s is shifted by one, resulting in a change in the data. As a matter of fact, similar parts are omitted.

Here, when attempting to change the size of the kanji character "Ishi" 1, it is done by multiplying the x direction by n and the y direction by n. If the fifth to eighth lines in FIG. 2 are Δy, n is 2, that is, twice the X direction, and m is 1.2.
When multiplied by 5, Δy is 4, so it becomes 5, and as shown in Figure 3, the distance between the original lines in Δy becomes 3, and the number of "0" and "1" in the X direction is doubled, Open the change point, connect the vector change points linearly as shown in Figure 4, interpolate the data, and create the interpolation line!゛As shown in Figure 5, fill in from rQJ in the X direction, and at the change point of the interpolated vector data,
Generate an interpolation line by switching ``0'' and ``l'',
This results in the generation of characters of varying sizes. Furthermore, as shown in Figure 6, this kanji character ``1 stone'' is written as t.
In order to rotate anθ=115, when the data in the X direction is expanded, when the data is expanded by 5 dots, the address of the memory is increased by 1 dot in the y direction and expanded. From this address, expand 5 dots in the X direction, then increase the memory address by 1 dot in the y direction again, and repeat this operation.After expanding the data in the X direction in this way, perform interpolation in the y direction in the same way as above. .

FIG. 1 is a flowchart of the above-mentioned operation. To summarize the character generation method according to the present invention using this flowchart, first, vector data in the X direction is multiplied by the magnification factor in the X direction, Based on the results
Expand directional vector data. Next, convert the vector data of the next line into the distance (Δy) to the first line.
Expand the next line vector with an interval equal to the number of lines multiplied by the expansion rate in the direction, linearly connect the vector change point of the previous line and the vector change point of the next line, interpolate that data, and calculate the vector After interpolating all the changing points, fill in from "0" in the direction of the interpolation raster, switch between "0" and "1" at the changing points of the previously interpolated vector to generate an interpolated line, and create the desired size. It is possible to obtain unusual characters.

〔Effect of the invention〕

As described above, according to the character generation method according to the present invention,
Since characters are captured as vector data in the scan direction, especially in the raster direction, it is no longer necessary to fill in the character constituent parts as in the past, greatly speeding up document creation.
