al_get_current_inverse_transform3
Allegro 5 api
Usage
-
#include <allegro5/allegro.h> const ALLEGRO_TRANSFORM *al_get_current_inverse_transform(void)
Overview
Returns the inverse of the current transformation of the target bitmap. If there is no target bitmap, this function returns NULL.
This is similar to calling al_invert_transform(al_get_current_transform()) but the result of this function is cached.
Note: Allegro’s transformation inversion functions work correctly only with 2D transformations.
