xbox ps3 swizzled dds

[h3x3r]

Hey there. I need to figure out which pixel format uses this dds. If anyone know, please shere info. Thanks! It's PS3 swizzled and dimension are 256x128
It should look like this:

It looks like there is only one channel in the file (or paletted image without palette), because data is not compressed and 256 * 128 = exactly file size (1 byte per pixel). You can decode it for example as r8_snorm + swizzling in rawtex. It's not the original image, at least not without other supplementary data, like palette or something.

Thanks spirit for clarify... So there's no other way how to de-swizzle data without using pixel format? That colored image is captured by ninja ripper and saved as DXT5 which coresponds to the size of swizzled dds.

[spiritovod]

DXT5 is compressed format, where 4x4 block is encoded with 16 bytes, which corresponds to 1 byte per pixel as well, that's why the size is the same. But like it was already said above, the raw data you've provided looks more like non-compressed paletted image, so you need palette to reconstruct it - though in this case palette seems to be 16 colors only - unless the game is using shader-based coloring or something.

O.K figured it out. Thanks for hints spirit...
It was morton order + i found that palette table which was in the texture file.

Noesis code:

Code: Select all

  if rwTexPixelFormat == 11:
        untwid = bytearray()
        for x in range(rwTexWidth):
            for y in range(rwTexHeight):
                idx = noesis.morton2D(x, y)
                untwid += data[idx * 1:idx * 1 + 1]
        data = rapi.imageDecodeRawPal(untwid, bs.palette, rwTexWidth, rwTexHeight, 8, "b8 g8 r8 a8")
        texFmt = noesis.NOESISTEX_RGBA32

EDiT: Well seems like i am struggle with textures which don't have same width/height.
I solved textures with height power of two of width. But when it comes on power of four of width then i am lost.
This is code for height power of two of width. Means "width == height *2"

Code: Select all

idx = noesis.morton2D(y, x)
rwUntwid += data[idx * 2:idx * 2 + 2]

I must also swap x,y.

But how to on "width == height *4"?

EDiT: Got it. With this function: data = rapi.imageFromMortonOrder
