XnView Software

The classic XnView you have is maybe a x86 version (32 bits) while XnView MP is a x64 version (64 bits) and this can produce a different behavior from Windows OS. But you can read all details about this problem/feature on "https://learn.microsoft.com/en-us/windows/win32/api/winuser/nf-winuser ...

This is not really a BUG, is just a Windows feature (thank MS).

From Windows 10 an existing background application cannot open or place a foreground window when the user has another application on the foreground, instead Window will notify this foreground attempt as a yellow blink on the taskbar ...

Tested in XnViewMP 1.6.0 x64 on Windows 7/10/11. Found 3 small bugs (1a, 1b and 2).

1. Enable/disable of delete QPushButton (>) (allowing moving an item from the left/displayed list to the right/un-displayed list):

Hi Pierre,
I confirm that Unicode Exif user comments are now correctly displayed also as vignette/thumbnail labels in XnView MP version 1.6.0.

Thank you ...

BUT

This function computes the sum of absolute distance for successive Unicode characters (from input buffer) in both ways then compares results:

===========================
inline uint16_t SwapBytes(const uint16_t wch) { return uint16_t((wch >> 8) | (wch << 8 ...

Hi Pierre,
YES, you're right: "geraltW3_prew1.jpg" is an "hybrid" file as it has a JFIF segment FFE0 and an EXIF segment FFE1. And in EXIF segment the "User comment" is in BE format. The same format as in PNG file "00000-1192013237.png".

I send you my screenshots for these 3 images.

As I said, and ...

Hi Pierre,

I send you just 3 different files (the others are too big to be attached):

1. The first is a PNG image "00000-1192013237.png" with a Unicode tag "User Comment" and a ASCII/ANSI tag "Parameters" correctly shown both in ExifTool panel, just "User Comment" shown in Properties panel, and ...

XnView: MP 1.5.1 64 bit
OS: Windows

Unicode Exif User Comment(s) are printed as random Chinese characters (maybe a bad Unicode/UTF8 conversion ?) while ExifTool 12.51 prints the same information correctly.

Effect: The user can't see Exif user comment in explorer window.

To reproduce:
