Is there a .h file or method that could parse .astc like stbi parsing .png?

Hi, I am looking for a method could directly parse .astc file, any suggestions? Thanks!

Besides, from the
https://github.com/ARM-software/ktx-creator
it says "toktx --encode astc --astc_blk_d 6x6 --astc_mode ldr --genmipmap output.ktx input[s].png" could encode png to astc and wrap it to the ktx, but this command doesn't work and doesn't give me any error message, and I don't see any --encode astc message in the toktx --help. Is it deprecated? Any other command could transfer .png to .ktx? Thanks!

I don't know what a .astc file is so I can't help with that part of your question.

The ASTC encoder is included in the top-of-tree toktx which has not yet been released as we are still working on the normal mode feature. Presumably you are using the version from the Releases pages which is why you aren't seeing ASTC in the help. If you clone and build the software yourself, you will be able to create KTX files with ASTC-encoded payloads.

Thanks for reply, the .astc file is created by .png or .jpg ASTC encoder encoding.
