BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mirror editing method in a graphic editing apparatus that mirrors an image original and performs pasting processing.

0002

2. Description of the Related Art The procedure of a conventional image document cut-and-paste editing process on a graphic display screen will be discussed with reference to FIG.

For example, a graphic 51 is edited by cutting and pasting. The unit of cutting and pasting is performed using one rectangular frame, and the lengths of the rectangular frame size X and Y can be freely specified. When cutting out the figure 51 surrounded by a rectangular frame, the mouse cursor 52 is positioned at the coordinate point A. Then, coordinate point A is set as the base point of the cutting frame, and by moving the mouse cursor, a rectangular frame for specifying the cutting range is drawn. That is, the mouse cursor is sequentially moved from 52 (coordinate point A) to 53 and 54 (coordinate point B). The rectangular frame is also enlarged sequentially to 56, 57, and 58 as the mouse cursor is moved. Finally, in a frame 58 in which the graphic range of the cut portion 51 is contained within the rectangular frame, a cut rectangular frame is set at the positions of coordinate points A and B of the cut rectangular frame.

After setting the cutting range using the rectangular frame 58, a rectangular frame 59 of the same size as the cutting frame is displayed at a different position on the screen in order to set the position where the rectangular frame containing the cut figure will be pasted. , specify the paste position. After specifying the magnification of the transferred figure in the cutting frame and the pasting frame to be the same size or enlargement/reduction, the image original is relatively moved to another position 59 and pasted.

[Problems to be Solved by the Invention] Conventionally, cutting and pasting of cut and paste parts can only be performed in one rectangular frame, that is, word boundary, and cutting and pasting of figures can only be done by relative movement on the graphic screen. could not. For example, the procedure for cutting out a part of a complex figure and sequentially pasting the cut figures onto separate sheets of paper involves dividing the figure into multiple small rectangular frames, cutting them out, assembling them, and pasting them together, so that the figure does not shift dot by dot. It was necessary to make the operator aware of this. In other words, it has been impossible for the operator to be conscious of the number of dots on the graphic display screen and to synthesize figures divided into a plurality of pieces, or to paste asymmetric figures in a mirrored image.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, the present invention will be explained with reference to the drawings.

FIG. 1 is an explanatory diagram showing one embodiment of the present invention. In the figure, the mirror editing method in the figure editing device includes a keyboard 1 and a mouse 2 for specifying editing of an image original, a floppy disk device 3, an optical disk device 4, and a magnetic disk device 5 for storing image documents.
, an image scanner 6 for inputting an image original, an image printer 7 for printing an edited image, and a display 8 for displaying an image original are connected to a processing device 15 for executing and controlling editing processing.

The image scanner 6 reads the image original as binary data.

The image data saving section 10 includes a buffer and a window memory, and temporarily saves an image document on a graphic display screen. That is, it is used as a temporary storage location when image data for cutting and editing is temporarily saved or when a plurality of image originals are combined and edited.

The graphic control section 13 is a job control section 9.
Controls the display of the image original transferred from the computer, draws a trajectory as the mouse cursor moves, and draws a rectangular frame.

The display 8 includes a video memory and a display screen, holds the image document, rectangular frame, and mouse cursor, which are information sent from the graphic control unit 13, in the video memory, and displays the contents of the video memory on the display screen. .

The graphic coordinate analysis unit 12 calculates the cutting and pasting position by associating the dots of the image document with the graphic coordinate position according to the locus of the mouse cursor.

The keyboard 1 and the mouse 2 are used to specify a range or position using a mouse cursor or a graphic cursor (either one can be specified) when specifying a cutting range or pasting position of an image document.

The coordinate data analysis unit 11 performs calculations based on the graph coordinate data from the cutting range corresponding to the dot, and divides the figure within the rectangular frame into a plurality of dots along the cutting line.

The image data control section 14 compresses the image data when writing it into the image original storage file, expands it when reading it, and transfers the image original to the memory. It also performs density conversion on the image data and scales the image data.

The job control unit 9 transfers the image original read by the image scanner 6, and controls the transfer of the image original within the cutting and pasting range or the data transfer to various devices to be controlled.

The image printer 7 prints the image original transferred from the job control section 9.

The floppy disk device 3, magnetic disk device 5, and optical disk device 4 store and store compressed or uncompressed image original data.

FIG. 2 is a flowchart showing the processing of the above mirror editing method. In the figure, an example in which a part of one image document is cut out and pasted onto a separate blank document is explained. First, in step 21, the image scanner 6 reads the image document as binary data, and the image data control unit 14 reads the image document as binary data. The density of the document is converted, and the graphic control unit 13 displays a figure 41 (see FIG. 3) on the display 8.

In step 22, a rectangular frame 42 of the drawing 41 to be cut out is specified on the graphic display screen using the mouse.

Step 23 is the graphic coordinate analysis section 1
2, the dot coordinates of the cut range of the image original corresponding to the cut range of the graph coordinates (rectangular frame 42) by the mouse cursor are calculated.

In step 24, the length of each rectangular frame in the X or Y direction is determined in order to divide the cut rectangular frame 42 into a plurality of rectangular frames of 1 dot in the X direction and n dots in the Y direction. The range of the coordinate lengths X and Y can be specified from 1 dot to n dots (document size length dots/mm).

In step 25, the coordinate data analysis unit 11 calculates a cutting range using the designated number of dots and divides it into a plurality of rectangular frames.

In step 26, the cutting frame (rectangular frame 42) is redisplayed to confirm whether or not a line close to the cutting range has been set.

In steps 27 and 28, in order to determine the pasting position on the separate blank document, a confirmation cutting and pasting frame 43 is drawn on the separate blank document and the transfer position is set. At this point, the image data control unit 1 also specifies the scaling of the transferred figure.
4.

In steps 29, 30, and 31, if the pasting position is OK, the cutout figure is transferred to the pasting position by the job control section 9. At this time, mirror image conversion according to the instructions. When the transfer of the figure is completed in step 31, a separate image document 44 is created and the editing process is completed (step 22
).
