Abstract

PURPOSE:To display a frame continued to the next page on a display with the same image as that of printing by transferring data in an unprintable area to a printable area by dividing when a document is displayed in spread. CONSTITUTION:When the document is displayed on a display in spread and the display of the frame F exists in the document and also, the frame F is continued to the next page, the data in the frame F continued to the next page is developed on a work memory 12 with a dot image. Next, the position and the size of an area except for page margins B1, B2 and binding margins C1, C2 where the data in the frame F developed in the page of the document being displayed at present are found, and the data in the frame F developed on the work memory 12 is divided into found areas F1 and F2, and are transferred to a memory 11 for display. Thereby, image data in the frame F can be displayed on the display without being impaired.

Description

[Detailed Description of the Invention] [Industrial Field of Application] This station relates to document creation/editing devices, particularly graphic frames and
The present invention relates to a method of displaying a frame for displaying non-text data such as an image frame.

[Conventional technology]

Document creation/editing devices mainly handle character data, but they also need to handle non-character data such as graphic data. However, if it is attempted to process character data and non-character data using common software, the structure of the software will become too complex. Therefore, in document creation/editing devices that use both text data and non-text data, a special area called a frame is set up in the document, and the information within the frame is set up separately from the basic software that handles text data. The software for the installed frame ring is processing.

The types of frames include a figure frame that displays basic figures using a combination of straight lines and curves, an image frame that displays a bitmap image read by an image reader, etc., and a text frame that displays a character string in a figure frame. There are frames, table frames for writing numerical data, character data, etc. to be automatically calculated based on predetermined formulas, etc.

Now, consider the case where a document is displayed as a two-page spread.

In this case, the display of the document creation/editing device is displayed in the format shown in FIG. 5(a).

In other words, there is one page document area A1 on the left and right sides of the screen.
．． A2 is set adjacent to it, and page margins B, ,B, are set around its outer periphery. Further, binding margins CI and C2 are set in adjacent parts of both pages. In addition, the page document areas AI and A2 and the page margin Bl shown in the same figure
B2 and the page margin Bl, B
2 and the binding margins CI and C2 are virtual and are not actually displayed on the display.

When creating a document, character strings input from the keyboard are displayed only in the page document areas AI, A2 of each page, and are not displayed in the page margin B 11B2 and binding margins C+, Ca, which are non-document areas.

[Problem to be solved by the invention]

When creating a frame within this double-page document, it is usually created so that it fits within the page document area At, A2 of each page. However, when displaying a frame on both pages, as shown in Figure 5 (a), even though they are two-page spreads, the page margins and binding margins are ignored, and both pages are displayed as if they were one page. There may be cases where it is desired to display frame F across . Note that the frame here means not the frame itself but image information within the frame.

For example, when showing an explanatory diagram of a console panel in an instruction manual for a facsimile machine, etc., since the console panel is horizontally long, it cannot fit on one page.
Also, if you try to force the diagram to fit on one page, the diagram will become too small and difficult to read, failing to fulfill its original purpose. It is also conceivable to divide the horizontally long explanatory diagram into left and right halves and arrange them vertically, but this is not preferable because the actual arrangement of the console panel and the arrangement of the explanatory diagram would be inconsistent.

Therefore, it becomes necessary to print a diagram of the console panel across both pages.

However, when actually printing in such a display state, only the image information in the page document areas AI and AR is output, so in the printed image, as shown in Figure 5 (b), the page margin B1 ．． B2, binding margin CI, and the frame that covers C2 are not printed.

In document creation/editing devices, it is very important to print the image displayed on the display in its original form in order to improve work efficiency. It is extremely inconvenient that the image differs from the image printed on the document.

The present invention was devised to solve the above-mentioned problems, and when forming a frame across both pages of a two-page spread document, image processing is performed in consideration of page margins and binding margins. The purpose is to display an image corresponding to a document print image.

[Means to solve the problem]

In order to achieve the above object, the display method in the document creation/collection device of the present invention provides a two-page spread on one screen, each page consisting of a document area and a non-document area provided around the outer periphery of the document area. In a document creation/collection device that can display non-text data, if a frame for displaying non-text data, etc. extends across both pages of a double-page spread across the non-document area, the data within the frame is once transferred to the work memory, and then divided so as to avoid the non-document area and transferred to the display memory.

[Effect]

In the present invention, when a frame is formed spanning both pages of a double-page spread, the data within the frame is temporarily stored in the work memory prior to actual display.

When displaying, the data in the work memory is divided into both pages, and is transferred to the display memory and displayed within each page, avoiding positions corresponding to unprintable areas.

〔Example〕

DETAILED DESCRIPTION OF THE INVENTION Hereinafter, features of the present invention will be specifically described based on examples with reference to the drawings.

FIG. 1 is a block diagram showing an embodiment of the document creation/editing device of the present invention. In the figure, reference numeral 1 is a central processing unit that controls the entire document creation/editing device. keyboard 2
Alternatively, the character string 1 figure 1 editing instructions inputted from the mouse 3 are sent to the keyboard/mouse control unit 4 and the system bus 5.
After being supplied to the central processing unit 1 via the display controller 6 and subjected to predetermined processing and calculations, the data is supplied to the display 7 via the display control unit 6 and also stored in the memory 8.

Note that the contents of the memory 8 are supplied to the disk device 10 via the disk control section 9 at an appropriate timing or based on instructions input from the keyboard 2.

As shown in FIG. 2, the display control section 6 is equipped with a display memory 11 in a bitmap format corresponding to the display screen of the display 7, and furthermore, a part of the address area of this display memory 11 is provided with a work memory 11. Memory 12 is allocated. The work memory 12 is used to develop the data within the frame into a dot image as a step before actually displaying the document on the display 7.

When creating a new document, the document created using the keyboard 2 and mouse 3 is stored in the memory 8, and a dot image corresponding to the document is developed on the display memory 11 of the display control unit 6 and displayed on the display. The document is displayed on 7. In addition, when editing a document, an existing document stored in the disk device 10 is read out and stored in the memory 8, and also displayed on the display 7.
It will be displayed above, so you can edit this document.

Now, the process of displaying a document to be displayed in a double-page spread and displaying a frame spanning both pages will be described with reference to the flowchart of FIG.

First, as shown in FIG. 4(a), a document is displayed in a double-page spread on the display 7 (step 101). There is a frame F displayed in the document (step 102), and the frame F
spans both pages (step 103
), expand the data in the frame F that spans both pages as a dot image on the work memo January 2 (step 104).
.

Next, find the position and size of the area excluding the page margins B, B2 and binding margins CI, C2 that display the data in the expanded frame F within the page of the currently displayed document (step 105). . That is, the position and size (width of the page document area AI, A2) of the areas F, F2 indicated by diagonal lines in FIG. 4(b) are determined. Then, for the obtained areas F, . . . F2, the data within the frame F developed in the work memory 12 is divided (step 106) and transferred to the display memo January 1. As a result, the image data within the frame F is displayed on the display 7 without being damaged (step 107).

〔Effect of the invention〕

As described above, according to the present invention, when displaying a document in a two-page spread, by dividing the data in the unprintable area and transferring it to the printable area, the frame spanning both pages can be divided into two-page spreads and transferred to the printable area. The same image can be displayed on the display.
