11 void al_draw_scaled_rotated_bitmap(ALLEGRO_BITMAP *bitmap,
12 float cx, float cy, float dx, float dy, float xscale, float yscale,
13 float angle, int flags)
14
16 Like al_draw_rotated_bitmap(3), but can also scale the bitmap.
17
18 The point at cx/cy in the bitmap will be drawn at dx/dy and the bitmap
19 is rotated and scaled around this point.
20
21 · cx - center x
22
23 · cy - center y
24
25 · dx - destination x
26
27 · dy - destination y
28
29 · xscale - how much to scale on the x-axis (e.g. 2 for twice the size)
30
31 · yscale - how much to scale on the y-axis
32
33 · angle - angle by which to rotate (radians)
34
35 · flags - same as for al_draw_bitmap(3)

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