Exif Data #40

Closed Ninjasr closed 3 months ago

Ninjasr commented 3 months ago

Exif metadata fails to be carried over to the converted file no matter what settings I use. I've used both the encoder and Exiftool for metadata preservation. This is a deal breaker for me, since I have a lot of photographs that I'd like to convert.

What formats did you use? For example, from PNG to JPEG XL.

I assume you are on Windows?

Please, send me one of the source files you find problematic, so I can investigate. Upload it to a service like Disroot Lufi and send me a download link to contact@codepoems.eu

I converted from JPG to JPEG XL. I'll send the email right now. And yes, I am on Windows.

Everything works as expected on my end in 1.0.0.

If you're using ExifTool to view metadata, update it. If not, try a different tool like GIMP.

Assuming the following:

Your file is only run through cjxl (the reference JPEG XL encoder). If that's the case, it has to work.

Try using other converters such as XnConvert to see if there is any difference.

Keep in mind that metadata in JPEG XL is compressed with Brotli. It's a novel solution that many programs may not support yet.

I've done a few more checks and you're correct, it seems that the Exif data is copied over properly. Unfortunately, none of the programs I use bar Exiftool seem to display it properly. I've also tried XnConvert (although very briefly) and it didn't copy over the metadata.
