On the internet, you usually get images, that originally were PNGs with aplha chanel and were pasted on white background. Is there some way to substract the white from the zones, where the semi-trensparent colors merged with white to get back the semi-transparent color?
Deleting the white area using magic wand makes images look ugly on dark backgrounds.
Not without antialiasing/layering information, which the PNGs will not preserve. – Darth Android – 2013-07-09T20:55:00.983
