It is possible to uniformly describe various forms. Further, there is a function of registering the created color for the color display, and it is possible to correspond to these functions.

A document image in the structured description language is a format in which the contents of the document are prioritized without being tied to the original layout information, and is a method of assigning tags and attribute values to data in which characters and images are mixed. , Any tag
A document image in an XML format in which attribute value can be assigned can be preferably implemented, but is not particularly limited to this.
HTML with link function, S to set specific tag
GML or the like is also possible.

The relevant limit distance between unit data in the present invention is a distance for determining whether each unit data belongs to the same area or not. If the distance is longer than this, another area is used. It is used to determine the area and the initial stage, but it is not particularly limited to this.For example, the area that is shorter than this as the permissible distance for dividing the area into the opposite is the same area Can also. In particular, in character data, it is possible to determine a character area as a paragraph as a related limit line distance in the vertical and horizontal directions on the display, and a related limit character distance, but it is not particularly limited to this method. Instead, for example, only one of the related limit line distance and the related limit character distance may be set.

In the present invention, the order of the unit data includes the unit data designation order in the page description language and / or
Alternatively, the setting can be performed based on the designated vertical / horizontal coordinates and the setting of vertical writing or horizontal writing, but the present invention is not particularly limited to this. May not be set.

The division of the document image data area according to the present invention is a group of unit data for converting a page description language document image into a structured description language document image. Although one tag / attribute value is assigned, the present invention is not limited to this, and may include another area in this area. It may have a compounded structure in which other tags / attribute values are assigned to this.
