Embodiment An embodiment suitable for the present invention will be described below in detail with reference to the drawings.

FIG. 1 is a system block diagram of a document processing apparatus according to an embodiment of the present invention.

In the figure, 1 is used in a raster scan display method.
A CRT display unit 2 is a video RAM (VRAM) that stores display pattern information for one screen, and 3 is a display control unit that controls writing of pattern information to the VRAM 2 and reading to the CRT. Reference numeral 5 denotes a main memory having an area for storing a control program and document data as shown in a flowchart described later, and reference numeral 4 denotes a microprocessor (MPU) for performing main control of the apparatus. The MPU 4 has a keyboard 8 for inputting character data and the like, and a pointing device (PD) for designating a position on the CRT and inputting and editing graphic data.
9 is connected. Reference numeral 6 denotes a hard disk device in which document files and character fonts are stored. Reference numeral 10 denotes a printer for outputting a created document, and reference numeral 11 denotes a floppy disk device for storing a document file or the like. These constituent blocks are connected by an I / O bus 7.

FIG. 3 shows the state of the main memory 5 when document data is read from the hard disk device 6 or the floppy disk device 11 into the main memory 5 and typeset.
31 is format data in which information such as the typeface of the document is set, 32 is character data of the document, and 33 is line information data in which typeface information and character positions set when formatting the document are set. is there.

FIG. 4 shows a part of the format data of FIG. 31; 41 is a part relating to the overall definition; 42 is a part relating to the definition of the heading; 43 is a part relating to the definition of the highlighting character; There are a plurality of definitions for the types of headings and the types of emphasized characters of the document. However, all the typeface definitions in them are typeface 44, character size
45, the same format consisting of modified character information 46. It should be noted that the information such as the typeface and the character size is included in the expression of the character attribute.

5 shows the block data set in the character data of FIG. 32. FIG. 5 (a) shows the entire structure of the block data, and FIG. 5 (b) shows the character data 1 in the block.
(C) is a character modifier possessed for each character. The block in this embodiment is a functional area such as a heading character block 21, a normal character block, and an emphasis character block shown in FIG. In this example, a case is shown in which each block includes formula data. Each block is defined by a heading start, end command, emphasis start end command, and the like, for example, as shown in FIG. Also, when the formula is considered as one block, for example, the heading block 21 has a formula block further included in the heading block. Therefore, the modifier in FIG. 5 (b) can specify whether the character in the mathematical expression block depends immediately before the block, that is, depends on the typeface of the heading block or not. Therefore, it goes without saying that no matter how many blocks are nested, it is possible to define the dependence of the font and the like. Needless to say, these inputs are performed by a keyboard or the like.

In FIG. 2, it may be considered that the whole document is a single document and three mathematical expression blocks are present therein. If each expression depends on the typeface of the immediately preceding document, each mathematical expression includes three mathematical expression blocks. Depends on one sentence block, each formula,
The typeface for the heading of the sentence immediately before this can be made dependent on the typeface of normal characters and the typeface of emphasized characters.

Next, how the blocks in the document are typeset will be described with reference to FIGS. 6, 7, and 8. FIG.

First, the character data and format data of the document are read into the main memory 5 in FIG. In s6-2, initial data such as typeface information necessary for typesetting is set. In s6-3, it is checked whether there is a page to be formatted, and if not, the formatting of the document is terminated. If there is a page, the page is formatted in s6-4. In the typesetting processing, in the character positioning processing in FIG. 7 s7-1, all character positions in a page are set to line information while referring to font information and the like. At s7-2, all the characters in the page are output to the printer 10 or the CRT display unit 1 from the line information and the font information.

In the positioning process, first, in s7-3, one character is sequentially obtained from the character data at the head of the corresponding page, and in s7-4, it is checked whether or not the end of the in-page character data. If it is completed, the positioning process is completed. If there is character data, it is checked in the next s7-5 whether or not the command is a block start command.

If it is a block start command, s7-6 positioning processing in the block is performed, and the character position in the block is set in the line information. If not block start command, GE at s7-7
The position of one T character is determined and set to line information.

In the intra-block positioning process, information on the typeface of the text immediately before the block is set in FIG. 8 s8-1. In s8-2, one character GET is sequentially obtained for the first character data in the block.
Next, it is checked whether or not the character data ends in s8-3. If completed, the in-block positioning process is completed.
If there is character data, refer to the character qualifier of this character data in FIG. 5 s5-3 in s8-4, and refer to the information that the contents refer to the typeface of the sentence immediately before the block (character qualifier If the font data is O and the character size data is O), the font of the text immediately before the block set in s8-1 is used, and in s8-5, the character is positioned in the font, and the font data of the character qualifier is If it is not O or the character size data is not O, the character information is positioned according to the font defined by the character qualifier in s8-6, and line information is set.

In the output process of FIG. 7 s7-2, first, one character GET is sequentially obtained from the head character data of the corresponding page in s7-8, and it is checked in s7-9 whether or not the end of the character data in the page. If completed, the output processing ends. If there is character data, it is checked in the next s7-10 whether or not the command is a block start command. If it is a block start command, the character data in the block is output according to the line information in the s7-11 in-block output process. If it is not a block start command, one character GET at s7-12 is output according to the line information.

In the in-block output process, the typeface information of the text immediately before the block is set in FIG. 8 s8-7. In s8-8, one character GET is sequentially obtained for the leading character data in the block. Then s8
At -9, it is checked whether the character data ends.
If completed, the output in the block is terminated. If there is character data, refer to the character qualifier of this character in s8-10 in s8-10, and refer to the information that the contents refer to the typeface of the text immediately before the block (the type of the character qualifier) If the data is O and the character size data is O), the font of the text immediately before the block set in s8-7 is used, and one character is output in the font in s8-11. If the font data of the character qualifier is not O or the character size data is not O, s8
Outputs one character according to the typeface defined by the character modifier in -12.

With the above processing, it becomes possible to link the font of the character data in the block in the text with the font of the document, and to use a unique font in the block.

Next, an example of operation for changing the size of a character in a mathematical expression block will be described. In the entered formula,
Specify the character string whose size you want to change using PD9 or the like.
Next, a size change instruction is given (for example, as shown in FIG. 9 (a)).
This is performed using the virtual keyboard 91 on the CRT1. ) And a size change window 92 shown in FIG. 9 (b) are displayed to instruct the change. In this case, the size information specified in the window is recorded in the character qualifier shown in FIG. 5 (b). By setting the size data of the character qualifier to O, the size of the character can be made to depend on the size of the body again.

Here, the text indicates the standard size when using the mathematical formula software, and the standard size indicates the character size of the text defined in the format of the document.

Scripts refer to superscript / subscript characters and superscript / subscript characters as scripts. The size of a script entered in a set such as Σ or Iim is 1/1 of the standard size.
2

The script in the script indicates that a script is further added to the script, and the size of the script in the script is 1/4 of the standard size.

[Effects of the Invention] As described in detail above, according to the present invention, whether one of the character qualifiers of characters in an area is linked to the typeface definition of a document or the character qualifier unique to an area is used is one character in each area. If it is set to use a unique character qualifier of the area as a character qualifier of the characters in the area, control to output the characters in the area based on the unique qualifier of the area, Document processing device and document capable of controlling output of characters in an area in accordance with the typeface definition of the document when linked to the typeface definition of the document as a character qualifier of the character in the area It has become possible to provide a processing method.
