# al\_get\_current\_inverse\_transform(3)

Allegro 5 API

## NAME

al\_get\_current\_inverse\_transform - Allegro 5 API

## SYNOPSIS

-

  ```
  #include <allegro5/allegro.h>
  const ALLEGRO_TRANSFORM *al_get_current_inverse_transform(void)
  ```

## DESCRIPTION

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.
