Description

[Detailed Description of the Invention] [Summary] This invention reads the fonts of alphabetic characters and accent symbols corresponding to specified accent character information from a font storage memory in which the fonts of alphabetic characters and accent symbols are stored separately in advance, and The specified accent character font is generated by moving the accent symbol font relative to the read alphabetic character font, for example, moving it 1/2 above the body face and developing it in an overwriting manner.

[Industrial application field]

The present invention relates to an accent character generation device that generates an accent character font by synthesizing alphabetic characters and accent symbol fonts.

[Conventional technology]

Conventionally, accented characters such as "Å" shown in Figure 8 have been created by compressing the alphabet "A" vertically so that the alphabet "A" and the accent symbol "Γ" fit within the body face. The resulting blank space at the top was designed as an integrated font with the accent symbol ``Γ.'' This newly designed font was then used to print accented characters.

[Problem that the invention seeks to solve]

In this way, conventionally, a newly generated font was used so that the entire accented character fit within the body face, and a high-resolution (for example, 480 dpi) version for printing was created using a laser printer. As a result, the originally high-quality designed alphabetic characters were compressed vertically into poor character patterns, which caused the problem that they could not be used as full-scale printed characters.

[Means for solving problems]

In order to solve the above-mentioned problems, the present invention includes a font storage memory 2 that stores digital fonts of base character patterns and overlapping symbol patterns (hereinafter explained using alphabetic characters and accent symbols as examples) as independent fonts; an address calculation unit 3 that generates the address of the moved origin necessary for developing the accent symbol font read from the font storage memory 2 in accordance with specified accent character information; The corresponding English character font is developed in the buffer memory 5 with the origin as a reference, and the corresponding accent symbol font read from the font storage memory 2 is expanded in the buffer memory with the new origin generated by the address calculation section 3 as a reference. 5, and an overwriting section 4 which is developed in such a manner as to overwrite 5, and the overwriting section 4 outputs accented character fonts overwritten and synthesized.

FIG. 1 shows a basic configuration diagram of the present invention. The reading unit 1 in the figure reads the corresponding alphabetic character font 2-1 and accent symbol font 2-2 from the font storage memory 2 based on the accent character designation signal (character code, etc.), and then the overwriting unit 4 and the address operation are performed. 3, respectively.

The font storage memory 2 stores an alphabetic character font 2-1 and an accent symbol font 2-2 constituting an accented character in association with an accented character designation signal.

The address calculation section 3 generates the address of the origin for overwriting the accent symbol font 2-2 on the alphabetic character font 2-1.

The overwriting unit 4 stores the alphabetic character font 2-1 and the accent mark font 2-2 in the buffer memory 5.
It's written inside.

[Effect]

Next, the operation will be explained.

The reading unit 1, which has received the notification of the accent character designation signal, reads out the corresponding alphabetic character font 2-1, notifies the overwriting unit 4, and stores, for example, the alphabetic character font "" in a rectangular area surrounded by straight lines in the buffer memory 5. Write “A” as shown.

Next, the reading section 1 reads out the corresponding accent symbol font 2-2, and notifies the address calculation section 3 that this accent symbol font 2-2 has been read out.
-2 is overwritten, the calculated origin is notified to the overwriting unit 4, and a rectangular area surrounded by dotted lines in the buffer memory 5 (for example, 1/2 above the body face) is calculated. The accent mark font "Γ" inside the area moved to )
are written in an overlapping manner as shown in the figure.

Through the above procedure, it is possible to generate a high-quality accented character font by overwriting the accented symbol on top of the originally designed neat alphabetical characters and composing the accented character font.

〔Example〕

Next, using FIG. 2 to FIG.
The configuration and operation of the embodiment will be explained in detail.

In FIG. 2, the pattern moving unit 3-2 transfers the accent symbol font 2-2 read from the font storage memory 2 to the address calculation unit 3-1.
This is to move to a position based on the origin calculated by . The display 7 displays various information. The keyboard 8 is used to specify alphabetical characters and accent symbols constituting accent characters by inputting keys. In addition, 1,
2, 4, and 5 are equivalent to those shown in FIG. 1, so their explanations will be omitted.

In FIG. 3, the figure shows a state in which the "accent" command is inputted by key. This results in
The following steps are initiated.

The figure shows a state in which the alphabetic character "A" constituting an accented character is entered by key, and the accent symbol "Γ" is also entered by key. This means that the alphabetic character "A" shown in FIG. 4A and the accent symbol "Γ" shown in FIG. 4B are input from the keyboard 8. This key input is the 7th
This may be done using the character code shown in the figure.

The figure shows a state in which the execution key is input.
This activates the following procedure and automatically generates the specified accented character font.

The figure shows a state in which the digital font of the alphabet "A" is read out and written into a predetermined character string in the buffer memory 5. In this case, the reading section 1 reads out the alphabetical font 2-1 corresponding to the key-input alphabetic character "A" stored in the font storage memory 2, for example, the font shown in FIG. This means that the specified character string is written in the buffer memory 5 as shown in the rectangular area enclosed by solid lines in FIG. 4C.

The figure shows a state in which the digital font of the accent symbol "Γ" is read out. Similarly, the reading unit 1 reads the accent symbol font 2-2 corresponding to the key-input accent symbol "Γ" stored in the font storage memory 2.
For example, this means reading out a font as shown in FIG. 4B.

In the figure, the write address of the read digital font “Γ” is input to the address calculation unit 3-
1 indicates the state in which the calculation is performed. This is calculated by the address calculation unit 3-1 calculating the origin address (address of the upper left corner of the accent mark font) for moving the body face of the alphabetic font "A" upward by, for example, 1/2. It means that.

The figure shows a state in which the accent symbol font "Γ" is written to a character string in the buffer memory 5.
As a result, the accent mark font "Γ" is moved upward by 1/2 of the body face in a manner that overwrites the alphabetic font "A" that has already been written for the character string in the diagram. to produce the desired accented character font. As a result, an accented character font as shown in FIG. 4C is generated.

Similar to FIG. 4, FIG. 5 shows the process of generating an accented character font in which an accent symbol font "Γ" is attached above the lowercase alphabetic font "a".

FIG. 6 shows an outline of the character strings in the buffer memory 5. The alphabetical fonts "A", "B", "a", etc. in the figure are respectively placed at predetermined positions within the body face, which is originally designed with high quality. The accent mark font "Γ" attached to these characters is placed at a position shifted upward by a predetermined amount, for example, by 1/2 of the body face, without adversely affecting these alphabetic fonts. Therefore, it is possible to generate a high-quality accented character font in which accent marks attached to alphabetic characters are placed in optimal positions without degrading the quality of the originally beautifully designed alphabetic characters.

FIG. 7 shows an example of an accent character code according to the present invention. This is an example of an accent character designation signal inputted from the keyboard 8 in FIG. 2, and fonts shown in the figure are assigned to each character code.

〔Effect of the invention〕

As explained above, according to the present invention, the fonts of alphabetic characters and accent marks corresponding to a designated accent character are read out from the font storage memory in which the fonts of alphabetic characters and accent marks are separately stored in advance, and the read alphabetic characters The system uses a configuration in which the accent symbol font is moved by a predetermined amount and overwritten to generate an accent character font, so the accent symbol font can be placed in the optimal position without degrading the quality of the alphabetic font. It is possible to generate high quality accented character fonts. In addition, since accent character fonts are generated by combining alphabetic character fonts and accent mark fonts in a manner that overlaps them, there are fewer fonts that must be prepared in advance compared to the conventional case of preparing fonts for each accent character. The advantage is that the number can be reduced. Furthermore, there are two types of accented characters: uppercase and lowercase. Since the desired accented character font can be obtained using the same composition method for both, there is no need to take the trouble of checking the uppercase or lowercase letters. do not.
