Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a document processing method and apparatus capable of displaying / editing document information.

[0002]

2. Description of the Related Art Conventionally, in a document processing method and apparatus capable of displaying a plurality of layers of documents, images and graphics and superimposing information of those layers on the same screen, a document processing method and device , The order of superimposing layers for displaying each information of an image and a figure was fixed in advance and could not be changed. Therefore, FIG.
When the priorities for layers are determined in the order of documents, figures, and images as shown in 5, the display is only as shown in FIG.

However, in the above-mentioned conventional technique, since the layers having the respective information are superimposed and displayed in a fixed order, for example, when it is desired to display all the image data of the image layer in FIG. 15, as shown in FIG. In order to display the entire image because it was not partially displayed by the graphic, the image data had to be moved to a position that did not overlap the data of the document layer and the graphic layer.

This is also the case with graphic data, and in order to prevent the graphic data from obscuring the display of the graphic data, the graphic data had to be moved to a position that did not overlap the data in the document layer. .

As described above, when the data type to be prioritized differs depending on the created document, it is very inconvenient for the priority order to be fixed.

Also, the means for superimposing the layers is fixed, and the degree of freedom of the documents that can be created is limited.

Conventionally, when the stored document data is called, the first page of the document is displayed.

However, in such a technique, in a document having a large number of pages, document editing is sequentially performed from the first page,
When resuming after interrupting on the way, the document called for resuming had to be searched while sequentially switching the display from the first page to the page where the previous editing was interrupted. Or the operator had to remember the page himself.

[0009]

It is an object of the present invention to enable the operator to instruct the order in which the multiple layers of a document are stacked and the stacking method, and to create a document with a higher degree of freedom.

An object of the present invention is not to limit the first page displayed when the document is called next time to the first page of the document, but to improve the operability of editing from the next time.

The 3D current edit data address and table are shown, and the case where the second page is being displayed.

Next, a more detailed description will be added with reference to FIGS. FIG. 3 shows a document such as that shown in FIG. 16 from the hard disk device 11 or the floppy disk device 10 to the RAM 1
5 shows the state after being read. The overall structure of A is composed of a header section 95, a data section 96, and other sections. The header section 95 is a section for controlling the entire file to be created, and an enlarged view is shown as a B header section. The data section 96 stores actual data such as J character data / page information, K graphic data, and L image data shown in FIG. Further, the C-current edit information section of the B header section stores an operating flag of 100, a displaying flag of 101, a D-current edit data address, etc., and details of the two flags of 100 and 101 are described. Is the current edit information section flag of F. Details of the D-current edit data address will be described later.

The flag indicating that G is in operation includes a bit 107 indicating that a character is in operation, a bit 108 indicating that a figure is in operation, a bit 109 indicating that an image is in operation, etc. Is ON and the other two bits are OFF.

When a command is given by the operator to change the type of input editing from the three types of character input editing 28, graphic input editing 30, and image input editing 31,
Replace this flag.

The flag indicating that H is being displayed is a bit 110 indicating that a character image is being displayed, a bit 111 indicating that a graphic image is being displayed, and a bit 11 indicating that an image image is being displayed.
2. There are a bit 113 indicating that a form image is being displayed, a bit 114 indicating that a grid image is being displayed, etc., and a "screen control" command 32 is instructed from the character input main menu 28, the figure input main menu 29, and the image input main menu 30. It corresponds to the character display 44, the graphic display 45, the image display 46, the form display 47, and the grid display 48 in the screen control submenu 23 which is displayed after being displayed. For example,
The bit 110 indicating that the character image is being displayed is the character display 44.

Is ON when black and white is reversed, bit 113 indicating that the form image is being displayed is ON when the command for form display 47 is black and white, and bit 114 indicating that the grid image is being displayed is a command for grid display 48. When the black-and-white inversion is not performed, it is turned off, and all of these bits are on unless the operator gives a non-display instruction. Also, even if a non-display instruction is given and turned off, it will be turned on if the instruction is given again.
It will change to the state of. It is for this reason that the operator can give an instruction to display / hide on the screen an arbitrary number of images other than the one being input / edited (internally, an arbitrary number of bits of the flag B indicating that the image is being displayed can be set). Changing to the OFF state, of course, the operator's operation is a simple input without being aware of it). Since the input bit is being edited for the bit of the flag indicating that G is operating, it is ignored even if a non-display instruction is given.

In the current edit data address table D, the absolute address of the data relating to the area currently being edited is set.

FIG. 4 specifically shows the contents of the addresses set in the D-current edit data address table of FIG.

The standard format data of I represents the format of the entire document, and the priority display order of the layer designated for the entire document is stored in 130. In addition, information about paper 108 and information about composition (ten
9, throat 110, number of steps 111, step height 112, step width 11
(3, inter-stage 114, etc.) are divided into several items. This start address is the format data address 10
It is set to 2. J character data, K graphic data,
The L image data is managed for each data and further for each page. The page information address 103, the character data address 104, the graphic data address 105, and the image data address 106 are related to the area currently being edited. The absolute address of the data is set. Here, the page currently being edited is the second page, so the second page information 120, 2
Addresses at the delimiters of the second page character data 121, the second page graphic data 123, and the second page image data 124 are set. The page information 120 includes the character size, typeface, line pitch, character pitch, page number, and layer overlap priority information of the document at the page breaks, which are in the original format of the previous pages. Since it may have been changed by various commands, it becomes necessary when typesetting and displaying an arbitrary page without referring to the previous page. When displaying an arbitrary page, refer to and compare this page information and format data (refer to items in page information with priority, refer to format data for items not in page information and then format), Typesetting is done.

As described above, independent data management, and further G
The presence of the flag indicating that the image is in operation and the flag indicating that the image is being displayed ensures that the images are independent. Inputting and editing characters / images / graphics by designating any position on the document without newly defining an area It can be performed.
