I use now the same order as windows explorer...
Missing in the 2.23/24 Changelog...

I think it's covered by Fixed: ... * Natural sort order , and I vaguely recall a forum article wanting this. :bugfixed:

About your unrelated XnViewShellExt isssue: Version 3.5.0.0 is still the same as two years ...

PAM is a close relative of PNM (portable any map) supported by FFmpeg (example). Like the binary PNM formats (P4..P6, the ASCII versions are P1..P3) it consists of a small text header followed by a binary bitmap. Arguably parsing a PAM header (P7 format) is simpler than parsing a PNM header.

Now I am not sure what selected option is actually active. I'm not sure what your input and output formats are. If JXR displayed as 24bits RGB is the input, and I try to save it as PGM (portable grey map), I get the colour mode box as in your screenshot with "4 grey colours" selected, and ...

Apparently XnView 2.22 and some earlier versions cannot handle transparency at zoom levels > 100%. This could be a new bug or feature, or I haven't found the settings to fix it, or it never worked, but I didn't see it, because I only recently looked at pictures with semi-transparent (0 < alpha < 255 ...

what's the problem? In addition to what others wrote: There is now a lossless WebP variant. I'm still unsure about their lossy format, but the lossless codec can create smaller pictures than PNG, and that's mildly interesting. :o

Apparently XnViewShellExt(64) 3.5.0 (2012) does not yet support ...

the correct dimensions are 5456x3632 in any other viewer
Tested with something claiming to be RAW Image Viewer (a simple GUI for dcraw 9.19) I get 5496*3656 for your ARW. XnView 2.20 agrees with these dimensions.

I vaguely recall that some viewers don't know how to handle pixels at the edges ...

Hi, after a quick test I fear that XnView 2.20 doesn't grok the output of jpegtran -arithmetic . Check out the odd README in jpegsr9a.zip:
According to the UCC (Uniform Commercial Code) law, IJG has the lawful and
legal right to foreclose on certain standardization bodies and other
institutions or ...

there is a "Set Icon" in the toolbar section of settings but it's greyed out

Stop - this forum is for MP, I'm off topic, sorry :(

Interesting, I never saw that, and apparently it works for me. So far I had four tools without icons, and arranged all other icons "logically", e.g., a group "hex ...

Hi, I'm unable to figure out which libpng is used in the various XnView tools. The bug tracker and forum threads mention 1.6x from 3..6. There was a vulnerability in 1.61 .. 1.67, maybe it is not yet fixed everywhere (I tried to put it directly into the bug tracker, but apparently the mutual spam ...

FFmpeg (the command line video/audio/image tool) uses another approach, it has a MD5 filter for its internal (raw) format. The same picture in different formats (after lossless conversions) would yield the same MD5 hash. I have a small script, in essence a one liner ...

XnView 2.20 does not more officially support Windows 2000 and older Windows platforms. For others applications that typically means that some parts of newer versions might still work. For English/French/German installations apparently only five files were modified in version 2.20:
- XnView.exe ...

In addition to what XnTriq already wrote: A = archive, an ISO standard. Requires embedded fonts and other features for long-term archiving. The Ghostscript folks claim that conversion to PDF/A is neither trivial nor recommended.

xnview wrote:Where do you have seen that?

I was just about to remove the link from wikipedia to this thread as ancient history (2006), but 2011 is not too ancient.

MediaWiki also hates this beast (not sure what they really use, presumably GIMP or Magick), I parked both versions in the Commons JPEG artefacts category.
