JPEG XL library for PureBasic

Posted: Mon Oct 23, 2023 4:33 pm
by D Ogre
I'm posting this source code for anyone that's interested in utilizing the JPEG XL format in their projects. This is an untested early version. It does compile under PureBasic LTS 6.03, but there may be some datatype errors and omissions. Feel free to modify and use any way you like. All I ask is for you to post any corrections, updates, and usage examples for the community.

Looks like you invested already a lot of work into it. I am totally going to test it tomorrow. I didn't want to ask for JPEG XL because some people who seem to run the internet want to see it dead (looking at you, browser developers!). I see it as good successor to the rather outdated jpeg.

Well, I hope you find it useful. Like I said, it's an early version. Don't be surprised if there's issues with it. If you get it working, please post your work. :D

Don't expect too much. I'm still busy with my Gerber module. :wink:
