DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a graphic processing device that inputs two graphics, stores and edits them, outputs them, and the like.

[Prior art] Figure 6 shows 5, for example, MULTICAD of Mitsubishi Electric Corporation.
- It is a block configuration diagram showing a conventional graphic processing device as shown in the MWS manual, and is a graphic input unit 1. It has an input graphic information storage section 2 and a graphic output section 3. The figure input unit 1 draws figures through interactive processing while looking at a graphic display using a stylus pen and tablet, plots figures drawn on a drawing with a cursor using a digitizer, or plots figures drawn on a drawing with a cursor, or Graphical information is input by inputting a drawing in the form of pixel-by-pixel data using an image reader, and automatically converting it into graphical data consisting of coordinate data, etc. In addition, if the input figure is input with incorrect data, the figure input section 1 can correct the figure data by using functions such as deleting, adding, changing, enlarging, and reducing twice the figure on the graphic display. This is done through dialogue processing even when children are young. The graphic information inputted in this way is stored in the input graphic information storage section 2 such as a magnetic disk device. The stored graphic information is read out as necessary and outputted by a graphic output section 3 such as a graphic display, plotter, or printer.

[Problem to be Solved by the Invention] Since the conventional graphic processing device is configured as shown below, it is difficult to arrange the graphic information when moving graphic information input in an area of a certain size to an area of a different size. In such cases, conventional devices first consider and decide on a new arrangement, and then delete, add, change, enlarge, or reduce the figure in the figure input section. It is necessary to change the layout using a correction function such as , etc., and this layout change work takes a lot of time.

This invention was made in order to solve the above-mentioned problems, and has the following objects: 1. 7 [Means for Solving the Problems] A graphic processing device according to the present invention includes a layout change rule input section for inputting constraints regarding a layout change of an input figure as a layout change rule, and a storage for storing the input layout change rule. a layout change instruction unit that inputs instructions on how to change the layout, such as area size, and a structure that extracts structural information from input graphic information stored in the input graphic information storage unit. an information extraction unit, a structure information storage unit that stores the extracted structural information, and an automatic placement unit that automatically changes the placement of figures for one input figure information based on the structure information and placement change rules according to placement change instructions. and a graphic information storage unit that stores automatically arranged graphic information.

[Operation] In the present invention, constraints regarding the layout change are input in advance as a layout change rule using the layout change rule input section and stored in the layout change rule storage section. When a figure is input, the structural information extraction unit 7 uses it as information necessary for automatic placement.
The structural information of the figure is extracted by ``1'', and when there is an instruction from the placement change instruction section, the automatic placement section follows the placement change instruction.''1
The layout of figures is automatically changed based on the structural information and the layout change rules.

[Example code] An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a block diagram showing the configuration of the embodiment, and the same reference numerals are used for the same or corresponding parts as in the conventional example, and the explanation thereof will be omitted. In the figure, 4 is a layout change rule input section for inputting constraints regarding layout changes as layout change rules, 5 is a layout change rule storage section that stores the input layout change rules, and 6 is a layout change rule such as area size, etc. 7 is a structure information extraction unit that extracts the structural information from the input graphic information stored in the input graphic information storage unit 2, and 8 is a memory for storing the extracted structural information. 9 is an automatic placement unit that automatically changes the placement of figures based on the input figure information based on the structure information and placement change rules in accordance with placement change instructions;
Reference numeral 10 denotes a graphic information storage unit that stores automatically arranged graphic information, and the stored graphic information is read out and output by the graphic output unit 3.

Next, the operation will be described using as an example the case where the figure shown in FIG. 2 is input.

First, the following layout change rule is input in advance from the layout change rule input section 4.

・The figure must be at least 3mm away from the boundary of the designated area.

・The blocks must be rectangular in shape and must not overlap.

・Arrow lines representing connection relationships are horizontal lines and vertical lines.

Consists of arrows.

・Arrow lines representing connections should not intersect as much as possible.

The input arrangement change rule is stored in the arrangement change rule storage section 5.

When graphic information not shown in FIG. 2 is input from the graphic input section 1,
The input graphic information is stored in the input graphic information storage section 2. The stored graphic information is read out by the structural information extraction section 7, and the structural information of the graphic is extracted. In the case of the graphical information shown in FIG. 2, it is classified into block parts and arrow line parts representing connections between blocks, and information about each block and connections between blocks is extracted. The extracted structural information is stored in the structural information storage section 8.
is memorized.

When changing the layout of a figure, the operator of the apparatus instructs, from the layout change instructing unit 6, the target area of the input figure to be rearranged and the area to which the figure is to be moved after changing the layout. For example, Fig. 3 shows the target area in the input figure for which the arrangement is to be changed, and Fig. 4 shows the area in which the arrangement is to be changed and the figure is moved by broken lines. The placement destination area is specified by the placement change instruction section 6.

When this arrangement change instruction is given, the automatic arrangement section 9 uses the area information, the structure information of the figure stored in the structure information storage section 8, and the arrangement change rule stored in the arrangement change rule storage section 5. The arrangement of the figures is automatically changed for the input figure information stored in the input figure information storage section 2, and the rearranged figure information is stored in the figure information storage sections 1 and 0. It is output by the output section 3.

FIG. 5 shows an example of graphic information whose layout has been changed. this is,
Based on the arrangement change rules, the automatic arrangement section 9 changes the arrow lines representing connection relationships without changing the shape of the blocks, leaving them rectangular, and repeats attempts to change the arrangement so that the blocks do not overlap, thereby satisfying each rule. This is an example of determining the layout and outputting it.

[Effects of the Invention] As described above, according to the present invention, the arrangement of figures is automatically changed in response to a desired arrangement change instruction based on the arrangement change rule input in advance and the structure information of the input figure. As a result, the amount of work required for changing the layout is reduced, and the layout can be easily changed in a short period of time.
