I'm interested to find a format that may support this way to store a picture, not PNG in particular. if you'll check BMP, it is possible to use 32 bit color in palette, except BMP doesn't use transparency at all. but technically it fits well to save the image by the analogy with alpha BMP plugin.

it looks easier to write custom exporter. is it possible to save the image data from paint.net in this format - 256 color RGBA palette with alpha channel saved?

there was a plugin that allows to save aplha in 32bit BMP, that would be enough to me to add low color support there even though its kind of hack as well. I also thought about targas, not sure if specs allow to save alpha in palette, yet the space is there. would like to stick to easy uncompressed format as I had both bmp and tga reading implemented.

well guys, the alpha. none of the exporters I know about actually save 8bit alpha in 32 bit palette. paint.net default png exporter only can export 8bit images with 1 bit alpha which is not what I need.

Hello. A while ago I was working on font exporter/importer for an old game and it used 256 color RGBA palette. I wonder if there is any format that supports such palette with alpha and if there is paint.net exporter for it?
