I thought I made it clear that I was using zopfli/zopflipng. They were built from the
zopfli source on GitHub.
When I tried the maximum compression command line with zopflipng, it took close to 4 days to compress a single 32MB png and managed to save 1679 bytes over the original command line compression. The original PNG converted from a Gigapixel Project image was 32,916,531 bytes, the first command line gave a 19,724,422 byte output file and the second command line gave a 19,722,743 byte output file.
