I\'ve been trying to save 8-bit PNGs (PNG8) using RMagick (http://rmagick.rubyforge.org/) and ChunkyPNG (https://github.com/wvanbergen/chunky_png) but have been unable to do so.
I\'m trying to create paletted PNG image (8-bit per pixel) that uses RGBA palette (32-bit per palette entry) using Cocoa framework*.
I am trying to distinguish PNG-8 and PNG-24 images with getimagesize or Imagick, but I don\'t quite know how to to it.
how is it possible to save my image, created with gd, as an png-8? it saves a开发者_运维知识库s gif with transparent channel well - but I want to use png-8.
