0 are document format management sections each forming the document data section 1o;
These are a rectangular area management section and a data management section.

The document format management section 7o manages format information related to the entire document such as paper size, columns, header footer information, etc. The rectangular area management unit 80 has information regarding a rectangular area in which data such as figures, images, and tables are arranged two-dimensionally in a document, and manages the position, size, and other attribute information of the rectangular area. The data management unit 90 manages attribute information and substance data specific to image data, such as resolution and encoding method.

FIG. 2 is a configuration diagram of the rectangular area management section 80.

In FIG. 2, 81 is the total number of rectangular areas included in the document, and 82, 83, 84, 86, and 86 are the page number where each rectangular area exists, the position of the rectangular area within the page,
These include the size of the rectangular area, the data number of the entity data stored within the rectangular area, and other attribute information. Here, the data number is an index indicating the number of data in the data management section 90. The page number 82, the position 83 of the rectangular area within the page, the size 84 of the rectangular area, the data number 86 of the entity data stored in the rectangular area, and other attribute information 86 exist for the total number of rectangular areas, 81.

FIG. 3 is a configuration diagram of the data management section 90.

In FIG. 3, 91 is the total number of data included in the document, and 92, 93, and 94 are a pointer to the storage location of the entity data, the byte length of the entity data, and the entity data, respectively. Substantive data includes attributes unique to the data, and its format is defined for each type of data. In the case of image data, resolution, encoding method, etc. can be considered as unique attributes.

A pointer 92 to the storage position of the entity data, a byte length 93 of the entity data, and an entity data 94 have a total of 91 pieces of data.

The operation of the image editing apparatus in this embodiment configured as above will be explained.

First, we will show how the data structure of a conventional image editing device is expressed in the data structure of this embodiment.

FIG. 4 is an explanatory diagram of a data structure in a conventional image editing device. 100 indicates the configuration of information regarding one image data. 1o1 is attribute information of image data, 102
is image entity data.

Attribute information 101 includes image data size, resolution,
Information such as encoding methods can be considered, but these can be divided into those that can be replaced with format information or layout information for the entire document, and attribute information specific to image data.

The size of the image data can be replaced by a sheet of paper having a certain size and a rectangular area having position and size information placed thereon. In this embodiment, the paper size is included in the document format management section 7o,
The position and size of the rectangular area are included in the rectangular area management section 8o. In addition, since the resolution, encoding method, etc. are attribute data specific to image data, the entity data 9 of the data management unit 90
Included in 4.

As an example, FIG. 6 shows a document consisting of two pages of image data of size 4, input from an image input device, expressed using the data structure of this embodiment. FIG. 6a shows the contents of the rectangular area management section 80, and FIG. 6 shows the contents of the data management section 90. In Figure 6a, the number of rectangular areas is 2, the first page and the second page have rectangular areas of the same size as A4 paper, and the number of image data placed within the rectangular area is 1.
and 2. Figure 6 shows that the number of data is two, and data 1 is arranged in two rectangular areas.
This shows how data 2 is defined.

Next, we will show that when such a data structure is adopted, it becomes possible to handle multimedia data and edit the data layout.

A feature of this structure is that the data structure is divided into a rectangular area management section 80 that manages document layout information and a data management section 9o that manages substance data.

Layout editing such as changing the data placement position and enlarging/reducing the data can be done using the page number 82 of the rectangular area in the rectangular area management section 80.
This can be realized by changing the position 83, size 84, and other attributes 86. Generally, such processing is performed by a layout editing device called a layouter. Furthermore, the internal format of the actual data is not defined in this data structure, but is defined for each medium such as text, images, tables, etc., so it can be applied to multimedia data regardless of the data type. Editing of each data is performed by a corresponding data editing device such as a text editing device or a graphic editing device.

As described above, the data structure shown in this embodiment completely includes the information possessed by the conventional image editing apparatus, and is a data structure compatible with multimedia. This results in
The document data created by this image editing device becomes a multimedia document consisting only of image data, and direct multimedia editing can be performed on this document data.

Effects of the Invention Since the conventional data structure was unique to image editing devices, the data could only be used by cutting and pasting part of the image data into other documents. Since it has a unified structure that corresponds to media data, it is also possible to directly edit document data created with an image editing device using another application run. Also,
Unified document management can be realized without the existence of a special document format such as an image data document, and the practical effects of the present invention are great.
