I remember once while trying out a tutorial using a function which made a custom shape out of the pixels in a layer. usually I've been selecting the pixels, making a path, and turning that into a custom shape. but the problem is that the path was never as perfect as the selection. its like the computer was just free-hand tracing the shape I wanted to give me a pretty-close shape. but with this other tool it made a shape that was the EXACT shape of the selected layer, no matter how big it became. can anyone tell me where to find this pixel again?
