I'm using Linux and have no access to any of Adobe's 'fancy' programs.
I'm trying to convert an existing PNG32 image with alpha channel to PNG8. I have tried the following methods:
convert original.png PNG8:new.png- Horribly distorts the image and preserving only binary alpha (Not Indexed alpha)
- GIMP - Fails as well, but produces better quality (good color quantizer) than ImageMagick.
pngcrush -rem alla -reduce -brute original.png new.png- Made the image smaller but didn't take quantization into account (Image has less than 256 colors), so output was still PNG32.
What else can I try?
