Title: Straight line drawing device
Inventor: KAWAMATA KATSUHIRO
IPC: G06T11/40
Filed: 1998-04-14
Abstract: PROBLEM TO BE SOLVED: To decrease overlaps of drawing points and also to reduce the amount of computation for each drawn line by using a line drawing processing means which outputs a straight line to draw a segment that secures connection between its start and end points. SOLUTION: A tilt decision means 4-0 of a line drawing processing means 4 determines whether a segment to be set between start and end points should be drawn in a horizontal or vertical line based on a relation that is defined between the horizontal and vertical differences in regard to the start and end points. Based on this decision, the length of the horizontal or vertical line is determined. Thus, a vertical line processing means 4-3 generates a vertical line as a segment to be drawn to secure connection between the start and end points. Meanwhile, a horizontal line processing means 4-4 generates a horizontal line as a segment to be drawn to secure connection between the start and end points. As a result, overlaps of drawing points can be decreased and also the amount of computation is reduced for each drawn line.
