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	 call-
       ing 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
	 different (and	more useful) order of operations: identity, scale, ro-
	 tate, translate.

       form(3),	al_compose_transform(3)
