That's not actually the right magic trickery necessary on Kindle (although it *may* work just fine in most cases).

(That one builds a 16c paletted PNG, i.e., decent for FBInk, although for better performance, no palette is still better).

What the Cover Mode does is instead this:

Code:

-define png:color-type=0 -define png:bit-depth=8

e.g., a 256c PNG8 w/o a palette; which ensures greater compatibility with all the weird Kindle bits involved.
