The swf_addcolor() function sets the global add color to the rgba color specified. This color is then used (implicitly) by the swf_placeobject(), swf_modifyobject() and the swf_addbuttonrecord() functions. The color of the object will be add by the rgba values when the object is written to the screen.
Megjegyzés: The rgba values can be either positive or negative.
