Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for creating and editing a document including a map and explanatory drawings, such as a word processor, a DTP system, and document creating software on a personal computer.

[0002]

2. Description of the Related Art Conventionally, when a document including a schematic map or an explanatory diagram is prepared by a document preparation device such as a word processor or a DTP system, it is drawn or drawn on a paper by using a figure forming function for inputting a pattern or a line segment. Use the scanner to read and paste what is on the screen, or use the illustration creation function to display the screen 1
I was drawing while filling in each dot.

[0003]

However, in the normal graphic function and image function, a modification line such as a solid line or a broken line provided by the system is used to draw a picture with a straight line or spline curve and a template such as a rectangle or a circle. Therefore, a special figure such as a map that requires a certain degree of accuracy is convenient for inputting the shape prepared by the system or the modified line such as a track, while the part not prepared by the system is accurate. In many cases, I had to use straight lines and spline curves to draw in freehand with great difficulty.

[0004]

This device is a document creation device having both a graphic input editing function and an image input editing function.
Figure editing display memory for inputting and editing and displaying figures, image editing display memory for inputting and editing and displaying images, and assigning images to the foreground with figures in the background By adding a display means for displaying a video in which the display data is combined, it is possible to create a drawing that combines the advantages of the graphic creation function and the image editing function.

[0005]

The present apparatus draws a rough drawing on the graphic editing display memory by the graphic creating means, and uses the drawing drawn by the graphic as a background, on the image editing display memory that overlaps as a foreground on the graphic background screen, The image creating means draws a fine portion of the drawing to complete the drawing.

[0006]

1 is a block diagram of an apparatus showing an embodiment of the present invention. This apparatus includes a processor unit 1 for controlling the entire apparatus, a ROM 2 storing a system control program and the like, a RAM 3 serving as a program work area,
Storage device 4 such as a hard disk or a floppy disk for storing data files of figures and images, a plurality of dot-matrix edit display screen memories 5 for expanding display data, a controller 6 for display, a CRT display And a display device 7 such as a liquid crystal screen, an input device such as a keyboard 8, a tablet 9 and a scanner 10.

In this apparatus, the rough sketch created by the graphic editing function is finely modified by the image editing function to finish it.
In other words, first of all, the part that can be easily drawn using the pattern figure provided by the system side and the modified line such as the track
After drawing as much as possible, use the image editing function,
Complete the figure by making detailed edits in dot units. In this device, the contents of the three edit display screen memories having the layer structure are displayed in an overlapping manner. Then, one data file is created for each editing screen, and data is input and edited individually. The bottom editing screen is for editing graphics (pattern data), and the middle and upper screens are for editing images (dot data). For example, in the case of the map of FIG. 2 created by this apparatus, each file is configured so that one map can be created from the data of the three edit display screen memories as shown in FIG. Therefore, when the size of the entire drawing is changed, the size of the drawing is changed by performing a process of changing all the data sizes of the data files belonging to the target drawing.

Next, a specific operation procedure will be described by taking the case of creating the map of FIG. 2 as an example. First, when the apparatus is activated, an initial screen for designating the size of the drawing to be created is displayed. When the input area of the map is shown as a rectangle on the screen,
An input editing screen is set according to the size of the area.
And, there are empty figure files and image files for saving the map data to be created,
Move to the figure input screen of FIG. The user selects a line shape such as various road lines and track lines, and draws a pattern such as a line segment, a curve, a rectangle, or a circle to create a rough part of a map as a background. In the case of the map in Figure 2, select the river decoration line to draw the flow with a curve, draw a straight line with the track decoration line to enter the track, and select the road decoration line to draw straight lines, curves, or circle patterns. Create a road outline by combining them and enter the stations and open spaces with solid lines to create a map outline. At this time, if the automatic synthesizing function of this device is used, lines such as road lines can be automatically synthesized. That is, the road drawn as shown in FIG. 5A is changed so that the intersection part of the road becomes natural.
Can be synthesized as follows. As shown in FIG. 6, this function separates the input contour lines of the same type of road from the filled parts inside and draws the contours of all road lines.
The overlapping part is composed by overlapping the fills within the line. In the figure file, figure data is usually constructed in the order of input, but when the automatic synthesizing function is used, the figures to be synthesized are grouped and stored as a group. For example, the graphic data file when the river, the railroad, and the road are input in FIG. 4 is as shown in FIG. 7A, but the data file after automatic composition is as shown in FIG. 7B as in FIG. become that way. Normally, only lines with the same line modification and pattern but different thickness are combined, but the line type to be combined can be adjusted by registering, so all road lines can be combined as shown in Fig. 7 (c). , It is possible to combine only some kinds of lines. In addition, it is possible to freely swap the figures up and down in a group unit or to swap the figures up and down in a group. Therefore, even if the river is drawn above the roads, it can be replaced later so that it flows under the roads. Text (character) data can be input and edited on either the graphic screen or the image screen described later. Alternatively, one text screen may be separately provided on the three screens of the figure and the image.

After the rough portion is created using the graphic data, fine finishing is performed on the image editing screen. The image edit screen is an edit screen of dot data, which is displayed as if a transparent sheet is overlaid on the graphic edit screen, and the detailed portion is input and edited with the map drawn by the graphic as the background. FIG. 8 shows an example of the image edit screen. On this edit screen, the user
1 out of 4 types of nibs: pencil, eraser, erase, and transparent
Select one of them, and draw and edit each dot on the screen with a pointing device such as a stylus pen. It is easier to work with a tablet that is integrated with the display device. The pencil is a function to draw an image on the figure that is the rough sketch, and the eraser is a function to erase the image drawn by the pencil. The erase function is a function of erasing the lower graphic screen, and the transparent function is a function of restoring the graphic screen erased by the erasure. Use a pencil or the paint-out function to correct the part that cannot be expressed due to the vertical relationship of the background graphic data, or enter the part you want to draw in detail in dot units. For example, the circle in front of the station drawn with a circle in Fig. 4 can be used to make a break by erasing, a handwritten line can be drawn with a pencil, or a photo read from a scanner can be attached to the sketch of the graphic screen in Fig. 4. It can be finished like 2. If you make a mistake in drawing, or even erase the necessary part, you can use the eraser or the transparent function to restore the mistake and redraw. As shown in FIG. 3, the image screen data is stored separately in an image data file and a mask data file. The image data file stores the image data of the image drawn by the pencil function,
The mask data file stores image data corresponding to the range erased by the erase function.

FIG. 9 shows a mechanism of overlapping display of a graphic screen and an image screen. The contents of the graphic data file and the contents of the two image data files are developed as images in a dot matrix edit display screen memory. The figure in the figure data file input by the figure function is developed and drawn in the edit display screen memory at the bottom so that the display pattern is on (1). In the edit display screen memory at the top, a portion where the image data is filled is drawn as on (1). Mask data is drawn on the edit display screen memory in the middle so that the erased portion is off (0). That is, all addresses are turned on in the edit display screen memory when there is no erase data. The display controller 6 ANDs the same address data of both dot matrix memories so that the off address portion of the edit display screen memory of the mask data works as a mask area of the edit display screen memory of the figure. As a result, o on the figure edit display screen
Of the n portion, the portion corresponding to the off of the mask edit display screen is off. Further, by ORing this data with the data in the image edit display screen memory, screen data in which the on portion of the image edit display screen is overlaid is created and displayed on the display device.

By the above-mentioned mechanism, the contents of the three files are expanded in the three display buffers, respectively, so that each data can be edited at high speed and easily. Further, FIG. 10 is a flow chart of a control program stored in the ROM 2 of the apparatus for performing the above-mentioned drawing creation. As in step 1003, the three input edit screens automatically switch the input data when the edit menu is selected. In other words, when the input editing of the figure is specified in the edit menu, it is displayed in the figure display edit screen memory and the figure file, and when it is a pencil and eraser, it is displayed in the image display edit window memory and the image data file. Since control is transferred to the mask display edit screen memory and the mask data file, it is not necessary for the user to switch consciously. And because the graphic data, mask data, and image data are stored separately, you can easily create multiple drawings that differ only in part by creating a common background with graphics and writing different parts in the image. You can do it.
