14
15 int x, int y, fixed angle);
16
18 Draws the sprite image onto the bitmap. It is placed with its top left
19 corner at the specified position, then rotated by the specified angle
20 around its centre. The angle is a fixed point 16.16 number in the same
21 format used by the fixed point trig routines, with 256 equal to a full
22 circle, 64 a right angle, etc. All rotation functions can draw between
23 any two bitmaps, even screen bitmaps or bitmaps of different color
24 depth.
25
26 Positive increments of the angle will make the sprite rotate clockwise
27 on the screen, as demonstrated by the Allegro example.
