do_ellipse
Calculates all the points in an ellipse.
Description
void do_ellipse(BITMAP *bmp,
int x,
int y,
int rx, ry,
int d,
void (*proc
)(BITMAP *bmp,
int x,
int y,
int d
));
Calculates all the points in an ellipse around point (x, y) with radius
rx and ry, calling the supplied function for each one. This will be
passed a copy of the bmp parameter, the x and y position, and a copy of
the d parameter, so it is suitable for use with putpixel(). Example:
void draw_explosion_ring(BITMAP *bmp, int x, int y, int d)
{
...
}
do_ellipse(screen, SCREEN_W/2, SCREEN_H/2,
SCREEN_H/16, SCREEN_H/32, flame_color,
draw_explosion_ring);
