SYNOPSIS

9              #include <allegro5/allegro.h>

11              void al_transpose_transform(ALLEGRO_TRANSFORM *trans)

DESCRIPTION

14       Transposes the matrix of the given transform.  This can be used for in‐
15       versing a rotation transform.  For example:
16
17              al_build_camera_transform(camera, 0, 0, 0, x, y, z, xu, yu, zu)
18              al_copy_transform(inverse, camera)
19              al_transpose_transform(camera)
20              // Now "inverse" will be a transformation rotating in the opposite
21              // direction from "camera". Note that this only works if the camera
22              // position is 0/0/0 as in the example.
