Description

DETAILED DESCRIPTION OF THE INVENTION "Field of Industrial Application" The present invention relates to a document editing processing device for editing and printing document information including image information.

"Prior Art" Conventionally, a document editing processing device that has a function of electronically editing document information such as photographs and drawings in a document and printing it using a printer etc. is shown in Fig. 6. The system configuration was as shown.

This device includes a path line 10, a disk device 1, a main memory 2, a processor 3, and a display device 4.
, keyboard 5, mouse 6 and iOS (110
) is connected to the interface 7.

A processor 3 performs data processing and control of this device. The main memory 2 is composed of a semiconductor memory or the like, and stores operating programs and the like. The display device 4 is a display device such as a cathode ray tube display. The keyboard 5 is a known human-powered device provided with key switches in a predetermined arrangement, and the mouse 6 is a known input device that freely moves a cursor on a display without relying on key switches. The I/O interface 7 is a circuit that controls output when data communication is performed with various other devices (not shown).

The disk device 1 is a so-called large-capacity memory containing a magnetic disk, and is provided for storing document information and other information.

Here, for example, text information is manually processed using a so-called word processor while displaying the content on the display device 4 using the keyboard 5. Of course, it is also possible to do it manually using a floppy disk or online from an external device. This character information is stored in the disk device 1 as a character file containing a large number of character codes.

On the other hand, image information such as photographs and drawings is sent from an image reading device (not shown) via the I/○ interface 7, and is input to the disk device as an image file that is a collection of image signals in units of pixels.

Now, there are two methods for storing document information containing a mixture of text and drawings.

One of them is a method of creating a document file 11 consisting of a character record 12 and an image record 13, as shown in FIG. The character record 12 is composed of character codes, their control information, and the like. The image record 13 includes an image file name for accessing the image file 15, its control information, and the like. An appropriate number of character records 12 and image records 13 are stored in one document file.

The character record contains, for example, a character code of one character or many characters, and when the character record 12 is read, it is stored in the font memory 14 (Fig. 7) stored in the main memory 2 (Fig. 6). , character record 12
Conversion from the character pattern 16 to the character pattern 16 is performed. Furthermore, when the image record 13 is read, the image file 15 in which image data is stored is accessed based on the image file name contained therein.

From this image file 15, an image pattern 17 such as a drawing is obtained. When printing a document in which characters and drawings are combined, the character pattern 16 and image pattern 17 obtained in this way are combined on the image memory to create a composite pattern 18.
get.

Note that the image memory is included in the main memory 2 (FIG. 6). If this document file 11 is saved in the disk device 1 (Fig. 6), the text record 12 and image record 13 can be read at any time and the contents of these records can be changed to update or transcribe the document file 11. etc. can be done.

On the other hand, when printing a document, it is not advisable to obtain the composite pattern 18 from the document file 11 each time because it requires a lot of calculation time. Therefore, usually the composite pattern 18
as a new image file in disk family @1 (6th
(Figure).

"Problems to be Solved by the Invention" Now, even with respect to an image file obtained from a composite pattern, a specific portion thereof can be cut out and composited with other document files. This technology, for example,
It is introduced in Publication No. 0-55473. However, in general, the process of directly compositing image data requires relatively complex calculations, so when editing such as compositing is required, it is necessary to save both a document file and an image file with the same content. I try to leave it there. Regarding the image files, the image file 15 before composition shown in FIG. 7 is also saved together with the image file after composition.

However, storing the same document twice reduces the utilization efficiency of the storage device. In particular, since image files generally require a large amount of memory, it is extremely wasteful to store partially duplicated files.

Furthermore, the original document file 11 (FIG. 7) and the image file 15 to be called from the image record 13 therein must be stored in association with each other, which complicates user management procedures. In addition, some kind of management system is required for the document editing processing device itself.
That burden cannot be ignored.

The present invention has been made in view of the above points, and an object of the present invention is to provide a document editing processing device that can efficiently process document information including image data.

"Means for Solving the Problem" The document editing processing device of the present invention edits a document including image data, and the document editing processing device of the present invention edits a document including image data.
A character record, an image record, and image data are stored, the character record includes a character code string that specifies a character pattern, and the image record contains an address and an image in the document file that stores the image data. The present invention is characterized in that character patterns and image data are arranged based on the character record and image record, and image processing of document data is performed.

"Operation" The above-described document editing processing device stores the character record, image record, and image file in the same document file, so there is no need to access separate files. Therefore, it becomes easy to update and edit image data in a document.

“Example” The structure of the document file of the document editing processing device of the present invention is explained in the first example.
As shown in the figure.

This document file 21 is composed of a series of document data 24 and some image data 25a125b. The document data 24 is composed of a collection of character records 22 and image records 23.

FIG. 2 is an explanatory diagram showing the format of one character record 22.

The character record 22 includes an identifier 221, a character record ID 222, control information 223, and a character code 224. The identifier 221 is for identifying whether the second record is a character record or an image record, and the former can be represented by 1-bit data such as "0" and the latter by "1", for example. The character record ID 222 is for identifying and specifying a large number of character records 22 in this document data 24, and is, for example, data of about 32 bits.

The control information 223 specifies the font memory in which the character pattern of the character code 224 included in this character record 22 is stored, the position of the character pattern on the image, the size of the character, etc. It is data. The character code 224 can include not only one character but several characters. In this case, it is assumed that character patterns of all character codes 224 included in one character record 22 are read from the same font memory.

A large number of character records having the above structure are included in the document data 24 according to the character information.

FIG. 3 is an explanatory diagram showing the format of the image record 23.

The image record 23 includes an identifier 231, an image record ID 232, a start address 233, a data length 234, and control information 235. The identifier 231 is as described in the character record 22. The image record ID 232 is for identifying the plurality of image records 23 in this document arc 24. When the document data 24 consists of character information and one drawing, the image record 23
However, if several drawings are included in the document, there will be as many image records 23 as there are drawings. And document file 2
Image data 25a, 25b existing in 1.
The number of ... is the same as the number of image records.

The start address 233 indicates the start address of, for example, the image data 25a in the document file 21, and the data length 234 indicates how many bytes the image data 25a is. The control information 235 is data that specifies the dot arrangement rules and positions on the image of the image data 25a.

The document editing processing device of the present invention having the document file configuration as described above has a system configuration similar to that shown in FIG. 6 in terms of hardware.

FIG. 4 shows the display device 4, keyboard 5, and mouse 6, and a method for editing the document file 21 will be explained using this and FIG. 5.

First, in the editing work of document information, certain operations are performed while looking at a screen as shown on the display device 4 in FIG. Initially, only the file name display 41 (referred to as an icon) on the right side of the display device 4 appears on the screen. Here, use the mouse 6 to select document #1.
Place the cursor on the icon 41 and press the mouse key 6.
When you press 1, the document file of document #1 is transferred to disk drive 1.
(FIG. 6) and its contents are displayed (Step 2 in FIG. 5). In this document screen 42, character information 43 and two pieces of drawing information 44 are present.

For example, when performing transcription processing on one of the drawing information 44, the cursor is placed on the drawing information and the transcription key 51 of the keyboard 5 is pressed.

Subsequently, when the key 61 of the mouse 6 is pressed, image data corresponding to the drawing information is read out from the document file (steps ①, ②, ② in Fig. 5).

In this case, the image record 23 (FIG. 1) in the document file is read by specifying the cursor, and the image data is read by the start address 233 and data length 234 therein. Only that image data is displayed, and once a file name etc. for saving it is given, the transcription to another file is completed (Step 2 in Figure 5).

On the other hand, if a specific image record is to be moved to another location in the document, the cursor is placed on the drawing information 44, the move key 52 on the keyboard 5 is pressed, and the key 61 on the mouse 6 is pressed. This moves on to the movement process (steps ■, ■, ■ in Fig. 5).

In the case of transcription, certain processing is performed to specify the destination area, etc., and in accordance with this, the control information of the corresponding image record 23 (Fig. 3) is updated (Fig. 5).
Figure step ■).

As described above, image data can be extracted from within a document and processed.

"Effects of the Invention" According to the document editing processing device of the present invention described above, character records, image records, and image data are stored in the same document file, so it is possible to have multiple files with the same content, or to store multiple files with the same content. There is no need to associate and manage them.

Therefore, efficient memory usage can be achieved, and image data can be easily handled.
