al_build_transform(3)	    Library Functions Manual	   al_build_transform(3)

NAME
     al_build_transform - Allegro 5 API

SYNOPSIS
	    #include <allegro5/allegro.h>

	    void al_build_transform(ALLEGRO_TRANSFORM *trans, float x, float y,
	       float sx, float sy, float theta)

DESCRIPTION
     Builds  a transformation given some parameters.  This call is equivalent to
     calling the transformations in this order: make  identity,  rotate,  scale,
     translate.   This	method	is  faster, however, than actually calling those
     functions.

     Parameters:

     * trans - Transformation to alter

     * x, y - Translation

     * sx, sy - Scale

     * theta - Rotation angle in radians

       Note: this function was previously documented to be equivalent to a  dif-
       ferent  (and  more  useful) order of operations: identity, scale, rotate,
       translate.
