Hi All,
Starting with all black pixels in an RGB image, I add a "Hide All" layer mask. If I save this as a PNG image and then use libPNG to inspect the resulting pixels, I would expect to find all black pixels with alpha values of zero. In other words, an RGBA image buffer containing nothing but zeros. However, what I find are white pixels with zero alpha!
Does anyone have any idea what’s happening here?
