To be added to <tt>imglib.h</tt>.
<lang c>#define plot(x, y) put_pixel_clip(img, x, y, r, g, b)▼
<lang c>void draw_line(
image img,
unsigned int x0, unsigned int y0,
unsigned int x1, unsigned int y1,
color_component r,
color_component g,
color_component b );</lang>
The implementation code:
<lang c>#include "imglib.h"
#define swap_uint(a, b) do{ unsigned int tmp; tmp = a; a = b; b = tmp; }while(0)
