It is in fact ImageData type of object.
And when doing type() it just returns "userdata".
But I need to know if it really contains data that is image data or not.
Becuase I don't know GLSL syntax and as far as i know some shader functions may not be compatible in every system.Ref wrote:Nice library.
Really dumb suggestion, how about doing the same thing using PixelEffects?
If I'm not mistaken (as usual) should be substantially faster?
