al_draw_scaled_rotated_bitmap(1) Allegro 5 API


#include <allegro5/allegro.h>
void al_draw_scaled_rotated_bitmap(ALLEGRO_BITMAP *bitmap,
   float cx, float cy, float dx, float dy, float xscale, float yscale,
   float angle, int flags)


Like al_draw_rotated_bitmap(3alleg5), but can also scale the bitmap.

The point at cx/cy in the bitmap will be drawn at dx/dy and the bitmap is rotated and scaled around this point.

  • cx - center x
  • cy - center y
  • dx - destination x
  • dy - destination y
  • xscale - how much to scale on the x-axis (e.g. 2 for twice the size)
  • yscale - how much to scale on the y-axis
  • angle - angle by which to rotate (radians)
  • flags - same as for al_draw_bitmap(3alleg5)

See al_draw_bitmap(3alleg5) for a note on restrictions on which bitmaps can be drawn where.
