Abstract

PURPOSE:To make it possible to perform the dynamic edition of a character string having font style information at high speed by performing the addition, insertion and deletion of the character string, referring to a specified table. CONSTITUTION:A style array 22 corresponding to character array data 21 to be an edition object is prepared. In the style array 22, the length of a character string and the index 22b of a font style table 23 corresponding to it are arrayed. The font style table 23 is composed of the combinations 23a of the kinds of fonts and the sizes 23b of characters. For instance, when characters are added, the font style information of the character just before the added character and the font style information of the added character are compared by referring to the table 23. When they are the same, the length 22a of the character string of the style array 22 of the just before character is made to be increased by the number of byte of the added character. When they are not the same, the font style information of the added character is added to the last of the style array 22.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of processing font style information when inputting characters in an editing device including a screen display device such as a word processor and an editor.

[0002]

2. Description of the Related Art In an editing device including a screen display device such as a word processor and an editor, a conventional method of processing font style information when inputting a character is to manage data relating to font style information to be set as a part of a character string. is doing.

FIG. 3 is a schematic view showing an example of such a conventional font style information processing method.

As shown in FIG. 3, the font style information 32a, 32b to 32n corresponds to the corresponding character strings 31a, 3a.
It is managed together with 1b to 31n, and when dynamically editing the character string 31a or the like, it is necessary to change all the data including the character string of the portion to be changed.

[0005]

As described above, in the conventional font style information processing method, when a character string is dynamically edited, all the data including the character string of the part to be changed must be changed. Therefore, it has a drawback that it is difficult to dynamically edit a character string having font style information at high speed.

[0006]

According to a method of processing font style information of the present invention, a font style table relating to the size and type of a character font defined in advance is held in a main storage device and an auxiliary storage device,
The font style information of the character to be added or inserted or deleted and the font style information of the original character string are referred to the font style table to add or subtract the length of the character string to add or insert the character string. It also includes deleting.

[0007]

Embodiments of the present invention will now be described with reference to the drawings.

FIG. 1 is a flow chart showing an embodiment of the present invention, and FIG. 2 is a format diagram showing a character arrangement, a font style arrangement and a font style table in a system utilizing the embodiment of FIG.

In FIG. 2, a style array 22 is prepared corresponding to the one-dimensionally arranged character array data 21 to be edited, and the style array 22 has a character string length (s
ize) 22a and the corresponding index 22b of the font style table 23 are arranged. The character array data 21 is used as a buffer for editing a character string.

The font style table 23 includes a combination 23a of font types and a font size 2
3b and a combination of font types 23
In a, it is possible to register, as one piece of information, a collection of several font types corresponding to the corresponding character code. When the font type or font size changes, it is added as new information.

Next, an embodiment of the present invention will be described with reference to FIG.

In the embodiment of FIG. 1, when a character string is added, the font style information of the character string is also specified by some means, and the addition, insertion or deletion of a character is always one character. It is done in units.

Immediately after starting the system, a font style table relating to preset font style information is created (step 1).

Next, it is judged whether the character having the font style information is added, inserted or deleted, and the processing route corresponding to them is selected (step 2).

When adding a character, the process proceeds to step 3 and a character to be added having font style information is added to the end of the character array data to be edited. The characters to be added at this time may be of any character code type. That is, either ASCII code or Japanese code may be used.

Next, the font style information of the character immediately before the added character is compared with the font style information of the added character (step 4), and if they are the same, the process proceeds to step 5 and they are not the same. If step 6
Move to. To compare the font style information of the character immediately before the added character with the font style information of the added character, refer to the font style table 23 using the index 22b in the style array 22 and perform a simple numerical value comparison. I can do it.

In step 5, the length (size) of the character string of the character style array 22 immediately before the added character is 2
2a is increased by the number of bytes of the added character.

In step 6, the font style information of the added character is added to the end of the style array 22, and the number of bytes of the added character is set in the added style array.

When inserting a character having font style information, a new character is added to the position of an arbitrary character in an existing character string (step 7).

Next, the font style information of the character immediately before and immediately after the inserted character and the font style information of the inserted character are compared (step 8), and if they are the same, the process proceeds to step 9 and they are If they are not the same, the process proceeds to step 10.

In step 9, the length (size) 22a of the character string of the character style array 22 immediately before or after the inserted character is increased by the number of bytes of the inserted character.

In step 10, the font style information of the inserted character is added to the position of the inserted character in the style array 22, and the number of bytes of the added character is set in the added style array.

When deleting a character having font style information, the character at an arbitrary position of the existing character string is deleted (step 11). That is, the length (size) 22a of the character string of the character is subtracted from the position of the character to be deleted (step 12). As a result, when the length (size) 22a of the character string of the character becomes 0, it means that the character string relating to the font style information does not exist.

[0024]

As described above, according to the font style information processing method of the present invention, the table relating to the size and type of the character font defined in advance is held in the main storage device or the auxiliary storage device, A character string having a plurality of font style information by dynamically adding, inserting or deleting a character string while referring to the character string in the main storage device or the auxiliary storage device and the table There is an effect that it becomes possible to edit at high speed.
