Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a graphic information processing device for displaying high-density graphic information on a graphic display device.

Conventional technology] Computer graphics technology 1 [j:%OADICA
It has been widely applied in the fields of M, OAK, etc., and graphic CRT display devices have been adopted as display means, and attempts have also been made to use flat panel display devices such as liquid crystal displays. Recently, with the realization of high-resolution graph ink display devices, mapping systems and drawing management systems have been developed that use graphic display devices to display high-density graphical information such as maps and drawings, and digitize and manage the information on computers. It is actively practiced. In such a graphic information processing device, in order to convert a drawing into graphic information and store it in a graphic information storage device such as a magnetic disk or magnetic tape, the drawing must be read using a coordinate input device such as a digitizer or drum scanner. That's what I do.

Problems to be Solved by the Invention Conventional graphical information processing devices can ensure high resolution when converting to graphical information, but the resolution of graphic display devices is such that even high-resolution CRT display devices cannot reproduce fine details on drawings. If you try to display the character 9 figures as they are at the same size as 1, it will become impossible to distinguish them on the screen.

For this reason, graphic processing has traditionally been performed to enlarge and display fine figures and characters, but simply enlarging and converting results in narrowing the distance between adjacent figures, and in areas with high information density, adjacent figures are The problem arose that comrades overlapped and became indistinguishable.

This problem is dealt with by correcting overlapping or too close together of the 9 character figures enlarged by the operator using a coordinate input device. However, when processing graphics such as maps, a variety of characters and shapes, such as place number 9 and building names, are printed multiple times, so manual position correction requires a lot of effort. .

Means and Effects for Solving the Problems In view of the above-mentioned circumstances, the present invention aims to save labor and speed up the correction work of graphic information including characters, and to improve Using the virtual display frame, automatic recognition means for overlapping or coming too close to other character 9 figures, and automatic processing of position movement direction and distance to avoid overlapping or coming too close to other character 2 figures using the virtual display frame A graphic information processing device comprising means for automatically correcting overlapping or coming too close to each other between a character figure enlarged and converted and two other character figures by repeating automatic recognition of overlapping or coming too close to each other and automatic processing for avoiding the same. This will give you a graphical display.

Embodiment FIG. 1 shows a configuration diagram of a graphic information processing apparatus to which the present invention is applied. In the figure, a computer 1 searches for and corrects graphic information including characters based on processing information.

It is used as a graphic information processing center that performs correction 9 editing and controls each peripheral device. The graphic display device 2 is a graphic information display device for displaying graphic information searched and edited by the computer 1. The coordinate input device 3 is used as a graphic information input device for requesting information processing and inputting correction information to the computer 1. The plotter 4 is used as a graphic information output device that prints graphic information displayed on the display device 2 as a drawing. The magnetic disk device 5 is used as a graphic information storage device for storing graphic information processed by the system.

The processing of the graphic information processing apparatus having such a system configuration, particularly the automatic correction process for overlapping or too close enlarged graphics, will be described in detail below.

The above system automatically reads drawings using the coordinate input device 3 and performs graphic information processing such as automatically correcting incomplete graphic information inputted manually by the operator using the computer 1, and converts the incomplete graphic information into a graphic as completed information. It has a processing function of displaying output to the display device 2 and plotter 4 or saving to the magnetic disk device 5.

In addition to such a processing function, it has an automatic correction processing function for graphic information, and performs three stages of processing described below in (1) to (3).

(1) First step (1-a) Display information consisting of graphic information and character information of the target page is read from the magnetic disk device 5 into the internal memory of the computer 1. Here, the graphic information is a set of data consisting of the display position and shape of the figure, and the character information is a set of data consisting of the display position of the relevant character string, 1 character, 2 character code, etc. .

(1-b) The computer 1 prepares a work area of the same size as the display information input in (1-a) expanded and displayed on the graphic display device.

(1-C) The computer 1 extracts only the display information and the sys form information, and develops the graphic information on the work area.

(2) Second step (2-a) The computer 1 extracts one piece of character information from the above-mentioned display information.

(2-b) Based on the display position (x, y coordinates) of the character information and the number of characters, a frame of the same size as the character information expanded and displayed on the graphic display device 2 is set on the work area. Hereinafter, this will be referred to as a virtual display frame.

(2-c) The computer 1 checks whether other character information or graphic information exists within the virtual display frame.

(2-d) If no other character information or graphic information exists in the check result in (2-c) above, develop the character information on the work area, and if it already exists, the character information Return to display information.

(2-1) Computer 1 uses the above (2-a) to (2-(
The processes up to 1) are repeated for all character information. Due to the processing up to now, text information that has a virtual display frame that overlaps other text information or graphic information remains in the display information.

(3) Third step (3-a) The computer 1 extracts one piece of character information from the displayed information.

(3-b) Set a virtual display frame for the text information on the work area.

(3-c) Check how the virtual display frame overlaps with other information.

(3-4) Based on the check results, the direction and distance for moving the virtual display frame to a display position where information does not overlap is tentatively determined.

Here, as shown in FIG. 2, the movable directions of the virtual display frame are set to eight directions: the X coordinate direction, the V coordinate direction, and the combined direction of X and V. It's 1.

The moving distance (moveable range) of the virtual display frame is determined by changing the size W of the virtual display frame in eight movable directions as shown in FIG.
, , wy is set to be movable in the ffi+V direction. In other words, the area is limited to nine times the size of the virtual display frame.

Further, the moving direction and distance of the virtual display frame are temporarily set as shown in FIG. 4, depending on the overlap with other information. In FIG. 4, a solid line indicates a virtual display frame for the text report, and a broken line indicates a display frame for other information. FIG. 4(a) shows a case where one of the four corners of the virtual display frame overlaps with other information, and in this case, the tentative determination of the moving direction and distance is to avoid overlap W.
Distances ΔX and Δy are tentatively determined in the +v coordinate direction, respectively. Figure 4 (1:+1) + (b2) is 1 of the virtual display frame
If a side overlaps with other information, it is tentatively determined to be moved by a distance ΔX or ΔV in the gi or V coordinate direction to avoid overlapping #). Figure 4 ((!I), ((j2) shows the case where two of the four corners of the virtual display frame along two axes or one side in the V-axis direction overlap other information, and two or two points to avoid overlapping are shown. The larger of the distance ΔZ+ +Δz2 or Δff/l + in the y-coordinate direction
The movement is tentatively determined by the length of the larger Δv2. Figure 4 (
, i) indicates a case where two diagonally located places among the four corners of the virtual display frame overlap with other information, and a distance Δ is set in the direction of combining π and V.
It is tentatively determined which of Zl+Δv2 and Δmouth+Δv1 will move in one direction.

Note that if the virtual display frame and other information completely overlap (the fourth
θ or vice versa), both the moving direction and the distance cannot be provisionally determined, and the character information for the display frame is stored as unmodifiable information. Also, if there are multiple directions in which movement is possible, multiple directions.

Tentatively determine the distance.

(3-e) A virtual display frame is temporarily set at a position on the work area where the moving direction and distance of the virtual display frame in 1 above have been temporarily determined.

(3-f) Check whether other character information or graphic information exists within the virtual display frame.

(3-g) As a result of the check, if it does not exist, expand the text information on the work area, and if it already exists, cancel the temporary setting of the virtual display frame and leave other movable directions and distances. If so, return to (3-e) above and repeat the steps of temporarily setting the virtual display frame, checking other information, and expanding on the work area.

(3-h) When there are no more movable directions in the processing of (3-e) to (3-g) above, the information is stored as non-modifiable information on the work area as non-deployable information.

(3-1) Repeat the processing in (3-a) to (3-h) 1 above for all character information.

(3-j) When all processing is completed, the information on the work area is stored in the graphic information storage device, and uncorrectable information is manually corrected by the operator. For this manual correction, the operator directly inputs the display position using a graphic display device or a sillite pen.

Note that although the embodiment shows the case of avoiding overlapping of the virtual display frame with other information, it can also be applied to the process of avoiding overlapping of the virtual display frame with other information. This is achieved by setting the size to include the

Effects of the Invention 9. According to the present invention, when fine characters and figures among high-density graphic information are enlarged and converted for display and storage, the enlarged information and other information do not overlap or come close to each other. Since the system automatically recognizes overlapping and automatically processes the direction and distance of movement to correct the position of information, it eliminates the need for complicated manual correction work and enables a highly efficient drawing management and mapping system.
