There's a color profile embedded in displaycomparisonfull.png.
Unlike some other programs (like PngOptimizer), XnView retains profiles.
IMO it's a bad idea to delete them without asking the user.
Thanks, I didn't check them all for stripping meta data but I just ran the latest Oxipng with '.\oxipng -o 4 displaycomparisonfull.png', and it reduced the test image to 93KB while retaining meta data / color profile.
So, even worse for XnView - 168KB versus 93KB, like for like.
P.S. Stripping the metadata only shaved off 2KB from the 93KB output.
oxipng is great, would be a lovely addition to a near perfect image handling tool (XnView that is ).
PNGs are sometimes a pain in the a** - so great to still see development in the encoder space

Concerning compression or optimizing tools - instead of integrating 'em into XnViewMP it might be feasible to add post-scripting capability - i.e. to run any script "cmd.exe yadayada.cmd $filename" or "powershell yadayada.ps1 $filename" with the filename input given by XnViewMP?
