PS4 texture decoding bugfix
« on: August 20, 2023, 01:21 »

Hi

First of all thanks for your tool and the source code, this has really helped me figure out how to read package content.
I was working on decoding PS4 textures and found this problem with your current algorithm, with some of the textures:



The texture resolution is 692x152 and that's what's causing the issue, in UntileCompressedPS4Texture:

Code:
// PS4 image is encoded as 8x8 block min
int blockWidth2 = max(blockWidth, 8);
int blockHeight2 = max(blockHeight, 8);

From what I found out, both blockWidth2 and blockHeight2 need to be rounded up to the nearest multiple of 8 instead. Doing so gives you the correct un-tiled result:



Just thought i would post the solution here in case you found it useful.


Again, thank you for all your work
