Therefore, trying to "Move" a selected "area" does nothing. I think the clarification you need is that an "empty area" or a transparent layer does not contain pixels. Any amount of hue or value makes a pixel "filled". The difference between transparent pixels and filled pixels are pixels which have a hue or value are actually rendered and seen as filled, even if there's 99.9% transparency. Every Photoshop document must be, at a minimum, 1x1px. Therefore if everything is transparent and you attempt to trim by transparency, nothing happens because Photoshop doesn't support 0x0px documents. it would then trim the document to nothing - 0x0px. if all that exists are transparent pixels and you choose the Trim command. It is not a command to use if you want to alter 100% transparent pixels.Īs for trimming. an RGBA pixel where you wish to alter RGB but retain the A. This command is helpful when you have partially transparent pixels and need to alter things like the hue, or luminosity of those pixels without changing the transparency - i.e. The lock transparency command could not be any more clear in my opinion. Why you appear to think you should be able to then alter the transparency is a mystery to me. don't allow transparency alteration to any pixel which has transparency.
