Description

[Detailed Description of the Invention] [Field] The present invention provides font data in an auxiliary storage device, reads out the font data for input characters,
The present invention relates to a character processing device capable of outputting in multiple sizes.

[Prior Art] Conventionally, font data in character processing devices capable of outputting in multiple sizes has been formatted in dot format (formant with dot data matching the output resolution of the character processing device), vector or stroke format (formant with dot data matching the output resolution of the character processing device), vector or stroke format (formant with dot data matching the output resolution of the character processing device). A format that has inflection points or feature points as their coordinate values or displacement values with adjacent points,
At the time of output, either converting the inside of the character outline into a filled-in dot pattern or performing CRT scanning) was used. By the way, when considering Japanese language processing, the number of characters required is, for example, 6877 characters in JIS C6226-1983 graphic characters. If these numbers of characters are prepared in the format, for example, a storage method that requires one hint for one dot of data (128 x 128 dots) requires 13.43 MB. For this reason, various compression techniques such as the RUN-LENGTH method have been devised, but it is necessary to prepare data in multiple sizes that match the output resolution of the character processing device, and it is necessary to prepare data in multiple sizes that match the output resolution of the character processing device. In order to output high resolution, the number of dots must be increased. Furthermore, when compressed data is used, it must be expanded again at the time of output, resulting in a decrease in output speed. Furthermore, enlargement conversion using dot interpolation has been devised, but the quality of the result naturally deteriorates. There is a vector (, z depends on the degree of compression in the case of a stroke font, but it is about 3 MB or less for the 6877 characters mentioned above, so it can be applied to a wider range of output sizes than one type of data, and can be used for long, flat, italic, etc.) It has a feature that dot fonts do not have, such as being able to easily transform it, but it requires size conversion, filling in the character outline, etc. when outputting, and the output speed is generally low, so all characters are output at high speed. In order to do this, the system price becomes expensive due to the addition of special hardware.Furthermore, if the output size is small (60 x 60 dots or less),
A meter during coordinate expansion.

It has drawbacks such as lower quality compared to dot fonts due to prefectural errors.

On the other hand, when considering the purpose of use of characters, frequently used characters for body text have a minimum of 6 points (1 point = 0.3 points).
514mm) to a maximum of about 12 points,
Characters larger than this size are less frequent, such as heading characters and emphasized characters. Furthermore, in terms of output time per character, frequently used characters must be output at high speed, but for less frequently used characters, even a low speed has little effect.

[Purpose] The present invention was made in view of the shortcomings of the prior art, and it is possible to simultaneously store font data in a plurality of different formats and select appropriate font data based on attributes such as input character size and transformation specification. It outputs a dot font for text characters that occur frequently but are small in size and have no deformation, and outputs a dot font for characters such as emphasis characters that are large in size and have deformation but are infrequent. Our aim is to provide a system that can do the following. In addition, small-sized characters that are frequently used can be output at high speed and with good output quality, and large-sized heading characters and emphasized characters that are less frequently used but are important in document creation can be output over a wide range. The second aspect is to provide a system that can output characters with deformation depending on the size.

Another object of the present invention is to take advantage of the strengths of different character data formats and combine them to create high-speed, high-quality text characters with a small storage capacity, and a wide range of size conversion and transformation. An object of the present invention is to provide a character processing device capable of processing heading characters and emphasized characters.

Another object of the present invention is to provide a means for simultaneously storing a plurality of font data composed of different formants, a means for specifying attributes for input characters, and a means for selecting and outputting font data suitable for the first character. An object of the present invention is to provide a character processing device having the following features.

First, the font data storage section in this embodiment will be explained. FIG. 2 shows the font data storage section. In this embodiment, as a plurality of font data configured in different formats, for example, dot formant fonts (hereinafter simply referred to as dot fonts) and vector format fonts (hereinafter simply referred to as hectorphones) are stored on an external disk. Prepare on H8. Dot font, Mincho typeface, and Gothic typeface 33 x 33

Setting of Character Attributes In the character processing device according to this embodiment, five types of character attributes (namely, text characters, emphasized characters, large headings, middle headings, and small headings) can be specified. The font type and output size can be specified in the text character attributes. In addition to the font type and appearance size, the character attributes for emphasized characters can include the long body ratio, oblique angle, and middle paint. Emphasized characters are characters that are used by being incorporated into the main text, and for example, it is possible to use the entire text as emphasized characters. Main heading, middle heading,
In addition, character spacing, line spacing 1 (distance to the previous line), and line spacing 2 (distance to the next line) can be specified as subheading character attributes. The above character attributes are in the format E'E'lE part C

Fig. 3-2 shows a flowchart of the format definition section, and Fig. 4 shows the contents of the character attribute table.

Selection of Font Data Next, the font data selection process will be explained using the flowcharts of FIGS. 3-1 and 3-2. A character string input, for example, kana, from the keyboard 50 in the input character processing unit FI7 is stored in a conversion buffer FI8, interpreted into a character code according to an internal dictionary F20, and stored in a character code buffer F19. On the other hand, the character attributes for the manually entered character string are selected on the CR7 screen by the keyboard 5o or pointing device 61 in the character processing control unit C1, and are stored in the character attribute flag Fl, and are further referred to in the switching operation S1 according to the contents of Fl. Determine the character attribute table. Here, character attribute table F2
is selected and referred to, the output size is determined by switching operation S3. Here, if the output size is stored in the external disk H8 as a dot font,
Characters are output by the dot font control unit CIO. In other cases, the vector font control unit Cll outputs the characters. When character attribute table F3, F4, F5, or F6 is selected and referenced, first. Deformation designation (i.e., long body ratio, diagonal angle,
Intermediate coating specification) is determined. If no transformation is specified,
Control is transferred to the above switching operation S3. If transformation is specified, the transformation parameters are set and characters are output using the vector font system (distributor CLL. Dot font i1i11 i, Tf1 section CIO is code buffer F1.
According to the contents of 9, the dot font data FIO is read from the external disk H8, and according to the output canister switching operation S2, the output canister FIO on V R A M H , i or the output canister FI on IMEM [1 1 8 is read out.

The vector font control unit C1l reads the vector font data F9 from the external disk H8 according to the contents of the character code buffer F19, performs coordinate transformation according to the transformation parameters, and then outputs it on the VRAM Hd according to the output canister switching operation S2.
