[Pkg-phototools-devel] Bug#809701: Please support using zopfli

Package: optipng
Version: 0.7.5-1
Severity: wishlist

As reported at
, Zopfli can produce Deflate-compatible streams appreciably smaller than
zlib, at the cost of significantly slower compression time.  Please
consider adding support for this in optipng, as a new, higher
optimization level (e.g. -o8).  (A corresponding low-level option should
exist to use Zopfli, which -o8 should enable along with the various
filter options.)
