NAME
al_draw_scaled_rotated_bitmap - Allegro 5 API
SYNOPSIS
#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)
DESCRIPTION
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.
