# al\_transpose\_transform(3alleg5)

Allegro 5 API

## NAME

al\_transpose\_transform - Allegro 5 API

## SYNOPSIS

-

  ```
  #include <allegro5/allegro.h>
  void al_transpose_transform(ALLEGRO_TRANSFORM *trans)
  ```

## DESCRIPTION

Transposes the matrix of the given transform. This can be used for inversing a rotation transform. For example:

-

  ```
  al_build_camera_transform(camera, 0, 0, 0, x, y, z, xu, yu, zu)
  al_copy_transform(inverse, camera)
  al_transpose_transform(camera)
  // Now "inverse" will be a transformation rotating in the opposite
  // direction from "camera". Note that this only works if the camera
  // position is 0/0/0 as in the example.
  ```
