Abstract

PURPOSE:To draw the segments of an image displayed on the graphic display with optional magnifications. CONSTITUTION:The image stored in an image storage area in a memory 13 is displayed on the graphic display 12 with optional magnifications. Coordinate information is read on the displayed image by using a mouse device 11 and the information is used to draw segments by a graphic display drawing device 17. Then the read coordinate information is converted by a coordinate information conversion device 16 by using the mouse device 11. Lastly, the converted values are used to draw segments in the image storage area 14 by an image storage area drawing device 18.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an image editing system for graphic display.

[0002]

2. Description of the Related Art FIG. 5 is a schematic diagram showing a means for drawing a line segment on an image by a drawing method in an image editing system in a conventional graphic display. Reference numeral 21 represents the state of the image storage area on the memory before the line segment is drawn. Reference numeral 23 is a state in which the image stored in the image storage area is displayed on the graphic display in the same size (hereinafter, displaying in this state is referred to as 1x magnification). 24, 2
As shown in 5, the graphic display is designated by the mouse device, the coordinate information is read, the line segment is drawn on the graphic display according to the read coordinate information, and finally the image on the graphic display is stored in the image storage area on the memory. By copying, a line segment is actually drawn in the image storage area. Reference numeral 22 represents the state of the image storage area on the memory after drawing the line segment.

Since the drawing result on the graphic display is copied to the actual image storage area, only a part of the image can be displayed on the graphic display at the same size. For parts that cannot be displayed at once, it is necessary to perform scroll processing before drawing.

[0004]

The image editing system in the above-mentioned conventional graphic display is as follows.
It is difficult to draw line segments for image details, it is not possible to draw line segments that exceed the range that can be displayed at one time, it is not possible to draw while looking at the balance of the entire image, When the line segment is drawn at the position, there is a problem that the line segment drawing operation and the scroll operation are performed, so that the work cannot be performed efficiently.

Composed of.

[0006]

The present invention will be described in detail with reference to the drawings.

FIG. 1 is a block diagram showing an embodiment of the present invention. In the figure, 11 is a mouse device, 12 is a graphic display, 13 is a memory, 14 is an image storage area, 15 is an image magnification conversion device, 16 is coordinate information conversion device, 17 is a graphic display drawing device, 18
Is an image storage area drawing device, and 19 is a control device.
An image storage area 14 in the memory 13 stores an image to be drawn.

FIG. 2 shows an example of an operation for displaying an image at the same size on the graphic display 12 as in the prior art. In the figure, 31 is an image storage area 1 before drawing a line segment.
4 and 32 are image storage areas 14 and 33 after the line segment is drawn.
Is a graphic display 12, 3 in which the image stored in the image storage area 14 is displayed at the same size.
Reference numeral 4 denotes a graphic display 12 or 35 that is in the middle of drawing a line segment on the displayed image, and graphic display 12, 36 that has finished drawing a line segment on the displayed image indicates an image storage area drawing device 15.

FIG. 3 shows an example of the operation for displaying an image on the graphic display 12 in a reduced size.
1 is an image storage area 14 before drawing a line segment, 42 is an image storage area 14 after drawing a line segment, 43 is a graphic display 12 in which an image stored in the image storage area 14 is reduced and displayed, 44 is a graphic display 12 or 45 that is in the middle of drawing a line segment on the displayed image. 45 is a graphic display 12 or 46 that has finished drawing a line segment on the displayed image.
The image storage area drawing devices 15 and 47 represent coordinate information conversion devices.

FIG. 4 shows an example of an operation for enlarging and displaying an image on the graphic display 12, which is shown in FIG.
1 is an image storage area 14 before drawing a line segment, 52 is an image storage area 14 after drawing a line segment, 53 is a graphic display 12 in which an image stored in the image storage area 14 is enlarged and displayed, 54 is a graphic display 12 or 55 in the middle of drawing a line segment on the displayed image. 55 is a graphic display 12 or 56 that has finished drawing a line segment on the displayed image.
The image storage area drawing devices 15 and 57 represent coordinate information conversion devices.

First, the case where an image is displayed on the graphic display 12 at the same size will be described with reference to FIG. The image stored in the image storage area 14 is displayed on the graphic display 12. The mouse device 11 is used to specify the starting point of the position where the line segment on the displayed image is to be drawn. When the mouse device 11 is moved, a line segment is drawn by the graphic display drawing device 17 between the moved point and the start point previously specified. Therefore, the mouse device 11 is moved until it becomes the line segment to be drawn. When the line segment to be drawn is reached, the mouse device 11 is used again to specify the end point. When the end point is designated, the image storage area drawing device 18 draws a line segment on the image stored in the image storage area 14 using the coordinate information of the start point and the end point read by the mouse device 11. Image storage area 1 in which line segments are drawn
The image in 4 is a new graphic display 12
Is displayed and the line segment drawing process ends.

Next, the image is reduced by using FIG.
A case where the entire image is displayed on the graphic display 12 will be described. The image stored in the image storage area 14 is converted by the image magnification conversion device 15, and the result is displayed on the graphic display 12. The mouse device 11 is used to specify the starting point of the position where the line segment on the displayed image is to be drawn.
When the mouse device 11 is moved, the graphic display drawing device 1 is provided between the moved point and the start point specified previously.
Since the line segment is drawn by 7, the mouse device 11 is moved until it becomes the line segment to be drawn. When the line segment to be drawn is reached, the mouse device 11 is used again to specify the end point. When the end point is designated, the coordinate information of the start point and the end point read by the mouse device 11 is converted into the coordinate information conversion device 16
The image storage area drawing device 18 draws a line segment on the image stored in the image storage area 14 using the converted coordinate information. The image in the image storage area 14 in which the line segment is drawn is converted again by the image magnification conversion device 15 and is displayed on the graphic display 12 to complete the line segment drawing process.

Finally, FIG. 4 is an enlarged view of the image displayed on the graphic display 12.
Line segment drawing processing is performed in the same manner as described with reference to FIG.

Although FIG. 2, FIG. 3, and FIG. 4 described the independent display states, in the present invention, the processing is performed while converting the display state into an arbitrary magnification during the line segment drawing processing. It can be carried out.

[0015]

Since the image editing system in the graphic display of the present invention can display an image at an arbitrary magnification to draw a line segment, the image can be enlarged and displayed to easily draw a line segment for a detail. To draw a line segment on the entire image at once, and to draw a line segment while checking the balance of the entire image,
The efficiency of image editing work can be remarkably improved by, for example, easily drawing a line segment at an arbitrary position on the image. Further, the display state of the image on the graphic display can be changed to any magnification at any time during the line segment drawing process.
