pngout /f6 does what ? :confused:

[SvenBent]

just a quick question as i cant seem to find these filter options documented anywhere

pngout /f6 keeps the original filter method ?
So if used on a file after pngwolf it will use pngwolf optimized filters but try to use kflate to compress the filtered data ?

Exactly, pngcheck -vv will display which filters are used.
