Mike Swartzbeck Posted May 31, 2024 Posted May 31, 2024 I've tried the "invert selection" command several different ways, but it's unresponsive. Is there something I've forgotten to do? Nothing special, just a pixel layer with some stuff painted into it. It's black line art that I want to reverse out to a negative image, that's it. Nothing fancy. A certain foto editor which I will not name could do this with a keystroke and no backtalk. Why is this so mystifying? Select a layer, tell it to "invert selection". What's so difficult? Quote
Brian_J Posted May 31, 2024 Posted May 31, 2024 I’m not sure if Invert Adjustment is what you’re after, or if you’re trying to invert a pixel selection.

NotMyFault Posted May 31, 2024 Posted May 31, 2024 This process inverts only areas which are not fully transparent (like the background in my example) If you want to get the white background inverted (to black), white pixels must be made opaque. Add a fill layer with white color as bottom layer, and use merge visible.

Mike Swartzbeck Posted June 10, 2024 Author Posted June 10, 2024 OK, that's much more clear now; thanks! Quote
Mike Swartzbeck Posted June 10, 2024 Author Posted June 10, 2024 Actually, inverting the area of the selection itself wasn't what I was after. My goof, perhaps; what I mean is that I wanted to invert the selected portion of the image — that is, create a "negative" of itself. Quote
airwhale Posted June 12, 2024 Posted June 12, 2024 On Mac, this is the button to invert the current selection. Weirdly, the option isn't available in the "Select" menu. Quote

It should be the 4th option in the Select menu, named Invert Pixel Selection - By default this uses the CMD/CTRL + SHIFT + I shortcut on desktop, but you can customise this in the app settings as required Quote
airwhale Posted June 12, 2024 Posted June 12, 2024 Thanks, it didn't make sense not being there. Guess the "pixel" word threw me off Dan C 1 Quote
