1.8.2: incorrect when displaying jxl with EXIF orientation
Posted: Tue Nov 12, 2024 10:30 am
XnView: MP 1.8.2 - 64 bit
OS: Windows10 22H2 64bit
When browsing jxl files with exif.orientation tags, the program will mistakenly rotate the image one more time according to the tag
Effect: jxl images are not displayed correctly
To reproduce:
1. download o6.zip and rename it to o6.jxl, which has exif orientation tag = 6 (90°counter clockwise, and the image should be rotate 90° clockwise). The content is letter F
2. open it with XnviewMP
Actual behaviour (bug): you will see "F" rotate 90° clockwise.
Expected behaviour: normal orientation of "F" like o6.jpg
Attachment illustration:
o6.jxl is compressed with cjxl from o6.jpg. Both of these 2 images has exif orientation tag = 6.
If you want to compress yourself, you can download cjxl here https://github.com/libjxl/libjxl/releases, and compress using cmd:
