ggtool's Issues

PNG to KTXBZ

Also ggtool doesnt convert all ktxbz to png, there are many skipped ones.
a few examples:
LowStreetBackHouse1Lamp-hd.ktxbz
BeachHermitCrab-hd.ktxbz
ArrivePart4-hd.ktxbz
and many others

Could you please add decompress and compress methods to ggtool?
PNG to KTXBZ
KTXBZ to PNG

Thanks

Convert ktx-textures to png

Maybe we should consider converting the ktx-textures to something like png?

KTX is a Khronos file format for sending prepared textures to the GPU. Looking at the RTMI-textures, they seem to be compressed with BPTC which is a format the GPU can decompress on the fly.

I couldn't find much about decompressing BPTC, except for this repo which contains C-code for decompressing them:
https://github.com/hglm/detex

I we're really motivated, we could port it to a sys-crate.

Another option is to create an OpenGL context and render the texture to a renderTexture to "read-it-back" so to speak. It can then be encoded to png with the png-crate.

Key extraction on macOS

Would this also work with macOS version? Or it’s only fir Windows?

KTXBZ file got extracted but not the PNG (macOS)

Getting this error while extracting some files. The KTXBZ file gets extracted, but not the PNG.

Unable to extract KTXBZ (macOS)

There are several KTXBZ files that I am unable to extract. The error seems related with the BZ compression.

Error when inflating, "unknown ZLIB method CM=0xf"

Hi there, currently using MacOS 12.6.

ggtool v0.1.0

Getting the following error when trying to extract EndStingers_1-hd.ktxbz from Weird.ggpack5a:

Error when inflating, "unknown ZLIB method CM=0xf", saving raw data.

Other ktxbz files don't have this error. Seems like there might be something unique about the "EndStingers_" series of files. (Although I'm getting a blank PNG with other ktxbz files.)

NEW ggtool doesnt make PNG

Your NEW ggtool doesnt make PNG anymore... I have to use old one to make it work.
Please fix it.

Example: extract 5a or 5b ggpack from RTMI. ktxbz is not converted at all. Png doesnt exist.

Extract data from Bank files

Functionality to extract data from bank files.

Release?!

Can you please release windows or linux binaries?
