Embodiment Construction
[0020] In conjunction with the accompanying drawings, the present invention will be described in detail below.
[0021] The present invention modifies the drawing algorithm according to the above-mentioned drawing process, performs a judgment in each step, has a branch, and then uses one of 16 specific line drawing functions to draw lines according to different branches. Include the following steps:
[0022] (1) Determine which line drawing function to use:
[0023] From attached drawing 2, we can see that, firstly, two points A(x1, y1) and B(x2, y2) should be initialized, and the distance between the abscissa and ordinate of A and B can be calculated. It is to calculate ax=|x2-x1|, ay=|y2-y1|, and then judge whether the two points A and B are within the holding range.
[0024] After the initialization is completed, judge the size of the abscissa of the two points A and B. According to the two results, it can be divided into two paths. The same judgment should be made for t...
