Joey, you are right. I have just realized that there’s a problem with the center point. It’s really interesting because I couldn’t align it to center perfectly; I mean It’s is already centered to layer and screen but whenever I try to move it relatively close to the center of the object, I could not have done it anyhow. This is the same for any PNG file exported from Illustrator with equal size and align options. This should have a trick or easier way; because it never perfectly matches to the center by moving manually, it just relatively matches and the move action of the object is uncertain. You or/and anybody show how?
