al@19128 1 pngquant converts 24/32-bit RGBA PNG images to 8-bit palette with alpha channel
al@19128 2 preserved. Such images are compatible with all modern web browsers and a
al@19128 3 compatibility setting is available to help transparency degrade well in
al@19128 4 Internet Explorer 6. Quantized files are often 40-70 percent smaller than their
al@19128 5 24/32-bit version. pngquant uses the median cut algorithm.
