Gran Turismo 4 (.ico, .img) [TEX1]

[BrunoElias2024]

Would like some help with these Gran Turismo 4 image formats - I like this series - I extracted the files a while ago and they are all in the compressed file I have left here. Please, if anyone knows how to convert these images to PNG, DDS or JPG I would appreciate it!!

I read that they are in a format called "tex1", I tried to convert it with some tools but I haven't found the solution!😊

You can get some good results with ImageHeat https://github.com/bartlomiejduda/ImageHeat

At offset 96 you can find fields like:
2 bytes (uint16) - image width
2 bytes (uint16) - image height
4 bytes (uint32) - palette offset

Ooooooh wow! Although I'm not very good with hexadecimal values, this tool was quite intuitive, even with my limited knowledge! Thank you so much, it's definitely the solution!😆

The model tool can be used to extract textures.

Using imageheat is not a proper solution because TextureSet1s (Tex1) can house multiple textures all swizzled together in one huge transfer for the GS memory.

Oh, likewise. I think Imageheat is a pretty good tool. Even with my limited knowledge, I was able to make discoveries like this (2CV logo).

Thanks to the tool you mentioned, I was able to achieve this other result. It definitely saves a lot of work! Thank you both so much!!!!!!!!
