void al_draw_bitmap(ALLEGRO_BITMAP *bitmap, float dx, float dy, int flags)
Draws an unscaled, unrotated bitmap at the given position to the current target bitmap (see al_set_target_bitmap(3alleg5)).
flags can be a combination of:
- ALLEGRO_FLIP_HORIZONTAL - flip the bitmap about the y-axis
ALLEGRO_FLIP_VERTICAL - flip the bitmap about the x-axis
Note: The current target bitmap must be a different bitmap. Drawing a bitmap to itself (or to a sub-bitmap of itself) or drawing a sub-bitmap to its parent (or another sub-bitmap of its parent) are not currently supported. To copy part of a bitmap into the same bitmap simply use a temporary bitmap instead.
Note: The backbuffer (or a sub-bitmap thereof) can not be transformed, blended or tinted. If you need to draw the backbuffer draw it to a temporary bitmap first with no active transformation (except translation). Blending and tinting settings/parameters will be ignored. This does not apply when drawing into a memory bitmap.
