al_build_transform(3)                                    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:

       o trans - Transformation to alter

       o x, y - Translation

       o sx, sy - Scale

       o 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,
         rotate, translate.
