XnView Shell Extension HEIC

[simon]

With the new version, options.. and convert ... can be open normally, but convert into jpeg-XL does not work at all. With v.1.1.5, the parameters were not accessible and the conversion was made in the lossless mode. With the the new version, the parameters are still not accessible, but not conversion is made. Attempting to convert in jpeg-xl even does not trigger the hourglass, it just closes the "convert window". (I checked that converting into png works as expected)

so output to jpegxl is only the problem?

[simon]

At least, it is the single issue I saw. Not a big issue as conversion to jpg-xl can be done by XnviewMP in batch mode, but at least a regression with respect to v.1.1.5 (able to convert but only losslessly) at this level

Please try to extract these dlls in the XnShellEx folder?

This does not change anything. I also made some additional tests with other formats. In summary
- jpeg-xl: no access to any parameter and does noting
- jpef-xr: no access to any parameter but generates a .jxr file that looks OK
- webp: no access to any parameter (but not sure there are some parameters to choose) but generates a .webp file that looks OK
- avif: no access to any parameter, freeze the explorer , and generates a .avif file that is empty (0 bytes)
- png, bmp, gif: works normally
- heif: I did not found an entry for it in the list of possible formats

if you install that?

[simon]

Same issue ... not really surprising as MS visual C++ (x64) was already installed on my computer (although an older version)

[simon]

I forgot to say that the reverse conversion (from jpeg-xl to standard jpeg) with "convert ..." works perfectly. All parameters (compression level, chroma subsampling, progressive or not) are accessible and the result is as expected

Please try to download/install the package, a problem with a dll

[simon]

With the new LibJPEGXL.dll, v1.1.6 behaves just as v.1.1.5: conversion to jpeg-xl is now possible again, but without access to any parameter, and this results in lossless conversion
