Abstract

PURPOSE:To output a drawing in which individual graphic can be distinguished clearly irrespective of the form of drawing, number of colors used etc. by removing painted out parts in the drawing and adding frame lines to paint out parts having no frame line. CONSTITUTION:A drawing data controlling function 2 writes/reads data stored in a drawing data memory 1. A display function 3 outputs drawing data received from the function 2 to a display unit 4. On the other hand, when printing the drawing data, a paint out removing function extracts data that indicate paint out of drawing data received from the function 2 and deletes the data. A printing function 6 removes parts having no frame line in the drawing data and replaces paint out parts having no frame line with frame lines and outputs to a printer 7. Thereby, a drawing in which individual graphic elements can be distinguished clearly can be outputted irrespective of the form of outputted drawing, number of colors used and number of colors that can be outputted by an outputting device.

) In the case of a line segment, the line segment is drawn according to the coordinate values shown in one drawing data (process 35).

In addition, in the case of a polygon, the code indicating the presence or absence of the second-to-last frame line in the two drawing data is determined, and the process branches to 28 or 29 depending on whether there is a frame line or no frame line. (Process 27). If there is a frame line, a condition is set that the graphic element to be drawn has a frame line (28), and if there is no frame line, a condition is set that the graphic element to be drawn does not have a frame line (28). Processing 29). Next, the code indicating whether there is a fill at the end of the drawing data is determined, and whether it is filled or not.

Branch to 31 or 32 (process 30). If there is filling, set the condition that the graphic element to be drawn is filled. Process 31); if not fill, fill the graphic element to be drawn. A condition that there is no such information is set (processing 32). Next, according to the set conditions, a polygon with vertices is drawn using the coordinate values stored in the drawing data (process 33), processes 25 to 33
By repeating the process until the process is completed, the graphics on the CRT screen can be output to the printer.

FIG. 8 is a flowchart showing the processing procedure of the fill removal function according to the present invention. First, drawing data is extracted in order (process 46) in the 0th order.

The graphic element type of the extracted drawing data is determined, and if it is a polygon, the process branches to process 48, and if it is a line segment, it branches to process 50 (process 47).

In the case of a polygon, the sign of the presence or absence of a fill instruction, which is the last data in the drawing data, is determined.

In the case of code "1" indicating that there is a fill,
In process 49, code "O" indicating no filling
In each case, the process branches to process 50 (process 48).
. If there is a filling instruction, the code indicating the presence or absence of filling, which is the last data in the drawing data, is changed to the code "O", which indicates that there is no filling (
Processing 49).

Then, if all the drawing data has been processed, a decision is made to branch to the end process, and if unprocessed data remains, to branch to process 46.
