Abstract

PURPOSE:To improve the maneuverability of edition by invalidating the output of a graphic drawn in either one page when the graphic covers on a boundary between two pages at the time of drawing the graphic by means of a drawing function. CONSTITUTION:Receiving a request signal, a graphic drawing device 7 extracts graphic data for drawing from a document memory 5. In order to find out a crip area indicating the ranges of respective pages displayed on a screen, a page control device 8 is driven. The page control device 8 finds out the coordinates of the crip area for pages existing in the screen on the basis of a line/column position of a document displayed on the upper left end of the screen and a page control table 9 and informs the obtained coordinates to the graphic drawing device 7. The device 7 draws a graphic in a display memory 10 by using the graphic data to be drawn and the coordinates of the crip area of the page concerned and displays the graphic on a CRT device 11. Thus, a graphic in each page can be drawn and editing operation can be made easy.

Description

[Detailed description of the invention] [Purpose of the invention] (Industrial application field) The present invention relates to a document creation device having a drawing function.

(Prior art) Conventional document creation devices create one document per page,
A page management method was used in which documents were read and edited page by page. However, recently, document creation devices have appeared that use a roll paper editing method that allows continuous document input and editing beyond page boundaries.

When using a document creation device using this type of page management, 1ijlI method, an operator can input and edit documents without being aware of page boundaries. Therefore, page boundaries may be set after a document is input, and in this case, graphics that have already been drawn may straddle the page boundaries.

Further, when drawing a figure using the drawing function, if the figure is near a page boundary, the figure may be drawn on another page as shown in FIG. 3, or may not be drawn because the position is inappropriate.

(Problem to be solved by the invention) In this way, when a figure is drawn using the drawing function and this figure straddles a page boundary, the figure appears on the display screen as if it were drawn continuously. However, when I print it, the figure is cut off.

For this reason, the operator's recognition of the figure on the display screen and the printed result may not match.

The present invention was made in consideration of the above-mentioned circumstances. When drawing a figure using the drawing function, if the figure straddles a page boundary, the output of the figure drawn on either page is invalidated. The purpose of the present invention is to match the operator's recognition of figures on the display screen with the print result, thereby improving the operator's editing operability.

[Structure of the Invention] (Means for Solving the Problems) In order to achieve the above object, the present invention provides a document creation device using a roll paper editing method that allows continuous input/editing beyond page boundaries. , a page management means for managing the number of lines on each page; and when drawing a figure on a created document, a page boundary is calculated from the number of lines on each page held in the page management means, and a figure is drawn on a page. Provided is a document creation device characterized by comprising: means for invalidating the output of a figure drawn on either page when the document straddles a boundary.

(For Info) With the configuration as described above, when a figure is drawn on a created document, if the figure straddles a page boundary, the output of the figure drawn on either one of the pages is invalidated. Therefore, the figure is drawn only on one of the pages, so
When printing, the operator recognizes that the graphics may be interrupted.

(Example) An example of the present invention will be described in detail below with reference to the drawings. FIG. 1 is a block diagram showing the configuration of this embodiment. 1 is a mouse that specifies coordinates when drawing a figure; 2 is a keyboard that has character keys such as symbols, alphabets, numbers, hiragana, and katakana; and function keys that specify various functions; 3 is a mouse 1 and keyboard 2; 4 is a document editing device that edits documents, figures, etc. and controls the entire device; 5 is a document memory for storing document data; 6 is a memory for displaying documents and figures; A character display device, 7 a graphics drawing device for generating graphics, 8 a page control device for creating rectangular information for each page displayed on the screen, and 9 a page management device for managing the number of lines for each page. A table 10 is a display memory for storing images to be displayed, and 11 is a CRT device for actually displaying images.

Next, the operation of the embodiment of the present invention will be explained in detail.

In Figure 1, first, use the mouse 1 to create a shape.
Or when a signal input from keyboard 2 is generated,
The input control circuit 3 operates to convert the signal into data (coordinates, numerical values, etc.) that can be recognized by the document editing device 4, and sends it out.

The document editing device 4 re-creates the data sent from the input control device 3 into a data structure that is easy to edit, and stores it in the document memory 5. Then, the document editing device 4 sends a request signal to the graphic drawing device 7 in order to draw the graphic instructed to be created on the screen.

When the graphic drawing device 7 receives the request signal, it retrieves graphic data for drawing from the document memory 5. Thereafter, the page control device 8 is operated in order to obtain a clip area indicating the range of each member displayed on the screen. The page control device 8 determines the clip area coordinates for the pages existing on the screen from the line/column position on the document at the upper left corner displayed on the screen and the page management table 9, and notifies the graphic drawing device 7 of the clipping area coordinates for the pages existing on the screen. do. When the graphic drawing device 7 receives the clip area coordinates, it draws the image in the display memory 10 using the graphic data to be drawn and the clip area coordinates of the corresponding page.

This is displayed on the physical screen CRT device: R11.

In this way, graphics can be drawn for each page.

As described above, according to this embodiment, the appearance of the text on the display screen matches the printed result, so the time required to create the final document is reduced. Furthermore, since other pages are not affected, editing operations become easier.

[Effects of the Invention] As described above, in the present invention, when drawing a figure using the drawing function, if the figure straddles a page boundary, the output of the figure drawn on either page is invalidated. This allows the operator's recognition of the figure on the display screen to match the print result, thereby improving the operator's editing operability.
