As described above, the chapters and sections of a document can be hierarchically managed using the chapter management table, section management table, page management table, and line page management table.

FIG. 17 is a structural representation example diagram for explaining a region primitive. The frame attribute designated by the pixel operation 100 in FIG. 5 is ON, and the flow of characters into the region is prohibited.
When the frame attribute specified above is OFF, normal character processing is performed. At that time, when the specified transparency attribute is ON, characters, ruled lines, figures, images,
And each pixel of the text is ORed to the lower layer,
If it is FF, the data in the lower layer is ignored. In FIG. 17, 88 is a text block, 87 and 89 are area primitives, and 90 is a ruled line primitive.

The structural expression of FIG. 17 is changed to a graphic expression as shown in FIG.
The line pitch of the line management primitive, the ruled line length of the ruled line primitive, the ruled line coordinates, and the region coordinate of the region primitive are set.

Here, as shown in FIG. 20, the characters "a" and "i"
In order to move the table in between, the chain of ab, cd, and de in FIG. 17 is cut, and ad, db, and ce are connected, and the movement of each primitive is completed. The coordinate value may be obtained by adding the horizontal length of the area primitive to the character feed amount of the "a" text primitive. Above, FIG. 19 shows the structural representation after the above movement.

The same applies to the case where a figure primitive, an image primitive, a ruled line primitive, etc. are connected as the area primitive data in addition to the text primitive.

As described above, since the ruled line data connected to the lower layer of the area primitive and each coordinate value of the text primitive are based on the area primitive, it is necessary to operate even if the table is moved. In addition, since the graphic representation of the area primitive is completely maintained and the character editing in the ruled line frame is completely independent from the text, the coordinate value of the character can be easily determined.

The same applies to the case of the graphic primitive and the image primitive under the area primitive, and moreover, the pixel operation 100 of FIG.
Depending on the transparent, opaque, and frame attributes specified by
5, figures below the rectangular area defined by Ymax26,
It is possible to control the transparency, opacity of images, ruled lines, text, and prohibition and permission of text flowing into a rectangular area. Moreover, each primitive can independently perform different pixel operations.

It should be noted that although the pixel operation has been described only for transparent, opaque, and frame, this attribute defines a pixel operation that is normally used in commonly-used graphics, so that more varied expressions can be made. it can.

Further, since the actual image according to the set value of the pixel operation in the area can be confirmed at the same time only by changing the setting of the pixel operation, the operability is high.

[0046]

As described above, the document editing apparatus of the present invention can easily realize complicated editing such as a table, a figure, a movement of an image, and a table set by defining a simple primitive called an area primitive. Moreover, since this area primitive is provided with an operation function by the pixel operation of transparent or opaque with respect to the lower layer of the area and prohibiting or permitting text flow into the area, each area primitive has a different pixel operation. It is possible to create a variety of documents, and the effect of greatly improving the expressiveness of documents and the processing efficiency of sentence shaping is provided.
