Resaving PNGs…
… and converting images from other formats to PNG…
… works flawlessly in v2.34 :bugfixed:

Can someone please confirm?

About some unrelated stuff I read here after some months off-line: Presumably you know deark mentioned in another thread, there is a working Windows 64bits binary in the tarball.

I had easy filter SmartCurve for years (presumably triggered by your PhotoShop plugin test thread), but almost never needed/used it. Because this plugin was mentioned in a recent Curves Filter thread I checked that I have it and what it does. Its smart curve suggestion for the original Lena scans (= click on "auto") is quite good. Something else you presumably know, but I didn't see it in the plugin thread, there are some free and some shareware Simple Filter plugins by a German photographer. The free versions work for me in XnView. The XnView ICC option claims to affect JPEG and TIFF, but actually it also works for PNG:

I knew about Jason Summers' site and use some of his software (TweakPNG in particular). deark escaped my notice, though. Wow! Danke for the hint :D

I've actually posted a link to SimpelFilter before but I failed to realize that they also have LE editions which are free. So again: Thank you for pointing this out!

Interesting series of articles by SimpelFilter's head honcho 8)

Thanks, but admittedly I suck at understanding French when almost all example pictures are broken URLs now. But I saw the surviving ICC color profile v2 or v4 test image: XnView groks all examples, Chrome only supports v2.

Windows stores color profiles in %windir%\system32\spool\drivers\color. Despite of the name system32 this is the 64bit version of system32 on a 64bit box. XnView as 32bits application can only see syswow64, but there is no %windir%\syswow64\spool\drivers\color. In the SysInternals book (available online for registered users) I found a trick for this hurdle, a 32bit application on a 64bits platform can access the 64bits system32 as %windir%\sysnative\spool\drivers\color. So now I have my own "calibrated color profile" configured as C:\windows\sysnative\spool\drivers\color\CalibratedDisplayProfile-5.icc.

(Cheating, actually I just copied the ICC profile to "C:\users\metoo\pictures\ICC tests\profiles", where XnView classic has no issues to access it.)
