The bitmap is rotated by `angle' radians clockwise. .PP The point at cx/cy relative to the upper left corner of the bitmap will be drawn at dx/dy and the bitmap is rotated around this point. If cx,cy is 0,0 the bitmap will rotate around its upper left corner. .IP \[bu] 2 cx \- center x (relative to the bitmap) .IP \[bu] 2 cy \- center y (relative to the bitmap) .IP \[bu] 2 dx \- destination x .IP \[bu] 2 dy \- destination y .IP \[bu] 2 angle \- angle by which to rotate (radians) .IP \[bu] 2 flags \- same as for al_draw_bitmap(3) .PP Example .IP .EX float w = al_get_bitmap_width(bitmap); float h = al_get_bitmap_height(bitmap); al_draw_rotated_bitmap(bitmap, w / 2, h / 2, x, y, ALLEGRO_PI / 2, 0); .EE .PP The above code draws the bitmap centered on x/y and rotates it 90° clockwise. .PP See al_draw_bitmap(3) for a note on restrictions on which bitmaps can be drawn where. .SH SEE ALSO al_draw_bitmap(3), al_draw_bitmap_region(3), al_draw_scaled_bitmap(3), al_draw_scaled_rotated_bitmap(3)
