#include <allegro5/allegro.h>

void al_draw_tinted_scaled_rotated_bitmap_region(ALLEGRO_BITMAP *bitmap,
   float sx, float sy, float sw, float sh,
   ALLEGRO_COLOR tint,
   float cx, float cy, float dx, float dy, float xscale, float yscale,
   float angle, int flags)

Like al_draw_tinted_scaled_rotated_bitmap(3) but you specify an area within the bitmap to be drawn.

You can get the same effect with a sub bitmap:

al_draw_tinted_scaled_rotated_bitmap(bitmap, sx, sy, sw, sh, tint,
    cx, cy, dx, dy, xscale, yscale, angle, flags);

/* This draws the same: */
sub_bitmap = al_create_sub_bitmap(bitmap, sx, sy, sw, sh);
al_draw_tinted_scaled_rotated_bitmap(sub_bitmap, tint, cx, cy,
    dx, dy, xscale, yscale, angle, flags);

See al_draw_bitmap(3) for a note on restrictions on which bitmaps can be drawn where.
