Conversion of a jxl image to jpg

[herb]

I am using NConvert.exe version 7.172 on a Windows 10 x64 system.

I try to convert a *.jxl image to jpg using the following command:

Code: Select all

nconvert.exe -half_res -ignore_errors -v -thumb 640 480 -overwrite -out jpeg -o testjxl.jpg test.jxl

All what happens is the following output:

Code: Select all

** NCONVERT v7.172 (c) 1991-2024 Pierre-E Gougelet (Feb 19 2024/14:50:40) **
        Version for Windows 7/8/10/11 x64  (All rights reserved)
** This is freeware software (for non-commercial use)

8 0

and no jpg file is created.

In plugins folder of NConvert I have all plugins of XnViewMP v1.7.2 - so also libJPEGXL.dll with date 17.4.2024

What is missing on my system or is it a general error?

Thanks for your help in advance

Hello Pierre,

thanks for your reply.
I have in plugins folder for
XnViewMP 1.7.2: libJPEGXL.dll - 17.4.2024 - 3955 KB
NConvert 7.172: libJPEGXL.dll - 7.9.2023 - 3277 KB

The fault happens with (newer) libJPEGXL.dll 17.4.2024.
Sorry, my fault, I have used this one.

But please allow the question: why do we have 2 different dll?

Best regards
herb
