al_invert_transform(3)	   Library Functions Manual	al_invert_transform(3)

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 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

	 Note:	Allegro's  transformation  inversion  functions	work correctly
	 only with 2D transformations.
