//Bresenham's circle algorithm void draw_circle(IMAGE *img, int xc, int yc, int r, int fill, unsigned long c) { // (xc, yc) 为圆心,r 为半径 // fill 为是否填充 // c 为颜色值 // 如果圆在图片可见区域外,直接退出 if(xc + r < 0 || xc - r >= img->w || yc + r < ...
The Bresenham's algorithm has quite low complexity due to its integer-based operations.Question 5: "This algorithm is more accurate than any other circle drawing algorithms as it avoids the use of round off function."Based upon the above statement, determine whether it is true or false.True ...
