SYNOPSIS¶
#include <allegro.h>
int is_inside_bitmap(BITMAP *bmp, int x, int y, int
clip);
DESCRIPTION¶
Returns non-zero if point (x, y) lies inside the bitmap. If `clip' is non-zero,
the function compares the coordinates with the clipping rectangle, that is it
returns non-zero if the point lies inside the clipping rectangle or if
clipping is disabled for the bitmap. If `clip' is zero, the function compares
the coordinates with the actual dimensions of the bitmap.
