So. I have gimp. I have flash cs4. I have a picture of a dog that is 200 by 200 pixels with alpha transparency (you only see the dog no background, it’s a png). Now I want to make only the dog listen for a mouseclick event. I saw some way of doing this by looking at the point where the mouse click event occured, and then stopping or continuing the event propogation based on if the pixel clicked was transparent or not. This seems sort of hackish. The “Clean” way I propose is by using a mask over the 200 by 200 image, but the mask should be shaped like everything that is NOT the dog. So it’s a mask with a hole in the middle. the hole in the middle being nothing. not even alpha. Or the other way if this isn’t possible, is to create a 200 by 200 image with just alpha value 0, and then stamp the dog on top as a mask… It appears there is nothing out there that describes how to do this. All I see are “bitmapfill” on squares and circles, which is utterly basic. Anyone got ideas?
