NAME

       al_invert_transform - Allegro 5 API

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   transformation   may   be   invalid.    Use
       al_check_inverse(3alleg5)  to  ascertain  if  the  transformation  has  an  inverse before
       inverting it if you are in doubt.

       Parameters:

       • trans - Transformation to invert
