Extracting alpha channel from grey scale PNG
Posted: Thu Jun 12, 2014 6:52 pm
I'm trying to extract the alpha channel from a grey scale PNG file without any luck. When I use the extract alpha channel option on XnView MP nothing seems to happen and on XnView the option to extract the alpha channel is grayed out. Converting to 32-bits first doesn't work either, on XnView MP I just get a white image with white mask. What gives?
