Two questions related to JPEG-XL functionality #579

Closed ZPNRG closed 1 month ago

ZPNRG commented 1 month ago

1) Is there a way from within PhotoDemon 2024.7 to see what version of the libjxl library is installed and being used by PhotoDemon? I'm curious since they have just a couple of weeks ago updated all of the v0.7, v0.8, v0.9, and v0.10 series of builds to v0.10.3, v0.9.3, v0.8.3, and v0.7.1. I would think that you would probably want to be using the v0.9.3 or v0.10.3 build, but I don't know what version PhotoDemon is downloading.

2) Where are the libjxl library file(s) being download/stored to? I have chosen since the beginning in 2022 when I started using PhotoDemon to use the portable version. That might change, but that is what I am still using now. It appears the libjxl library files are being downloaded to the App\PhotoDemon\Plugins folder. I see cjxl.exe, djxl.exe, and jxlinfo.exe. I have not investigated enough to know if you need to download and use any other libjxl files. I don't see any. From the file sizes, it looks like the current libjxl library files that PhotoDemon downloaded are not version v0.10.3 or v0.9.3, but I haven't investigated further.

Thank you for the question, @ZPNRG.

You can see the current libjxl version PhotoDemon is using in the Tools > Third-Party Libraries screen.

The PD stable release from earlier this week shipped with v0.10.0 of libjxl. I have just posted an update that supports the latest 0.10.3 libjxl . PD should offer to download the update the next time you interact with a JPEG-XL file, if your PD update options allow (Tools > Options > Updates).

Oops, I missed part of your second question. I'm sorry!

Where are the libjxl library file(s) being download/stored to?

As you discovered, all third-party libraries (including libjxl) are kept in PD's App\PhotoDemon\Plugins folder.

I see cjxl.exe, djxl.exe, and jxlinfo.exe.

These, plus the libjxl license file, are the only files PD downloads and configures. (These files are taken byte-for-byte from the associated official libjxl release, and you can overwrite them with your own copies at your leisure as new versions become available.)

I poked around in PD but somehow overlooked the Tools > Third-Party Libraries screen. I figured you had to have something like that somewhere. Sorry I overlooked that.

As far as the 2nd question I had, yes, I had also seen the libjxl license text file. I was wondering if I could simply replace the cjxl.exe, djxl.exe, and jxlinfo.exe files as new versions of jxl-x64-windows-static.zip were released. Thank you for letting me know that should be okay. Granted, if just interacting with a JPEG-XL file will force PD to do it, that would be easier/faster than me doing it manually.
