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 different (and more
         useful) order of operations: identity, scale, rotate, translate.
