SYNOPSIS
#include <allegro5/allegro.h>
void al_invert_transform(ALLEGRO_TRANSFORM *trans)
DESCRIPTION
Inverts the passed transformation. If the transformation is nearly
singular (close to not having an inverse) then the returned transforma‐
tion may be invalid. Use al_check_inverse(3) to ascertain if the
transformation has an inverse before inverting it if you are in doubt.
Parameters:
· trans - Transformation to invert
