Коммент к функции из исходников libpng:

Set the library compression level. Currently, valid values range from
0 - 9, corresponding directly to the zlib compression levels 0 - 9
(0 - no compression, 9 - "maximal" compression). Note that tests have
shown that zlib compression levels 3-6 usually perform as well as level 9
for PNG images, and do considerably fewer calсulations. In the future,
these values may not correspond directly to the zlib compression levels.
