Hi!

I finally had the time to test out the bindings. Unfortunately, I got into an issue. I want to assign the original byte array texture to a ktx2 one. Here is what I tried to do:

byte[] d3dtxTextureDataArray = textureData.SelectMany(b => b).ToArray();

fixed (byte* ptr = d3dtxTextureDataArray)
{
texture.PData = ptr;
texture.DataSize = (uint)d3dtxTextureDataArray.Length;
}

//...

fixed (Texture* ptr = &texture)
{
Ktx2.WriteToNamedFile(ptr, newKTX2Path);
}

I am almost certain I did something wrong, I get an exception when trying to save to a file (presumingly it doesn't allocate memory correctly): An unhandled exception of type 'System.AccessViolationException' occurred in Ktx2.NET.dll: 'Attempted to read or write protected memory. This is often an indication that other memory is corrupt.'

The file is created on the system, but there is no data inside it. I tried looking up the in the Khronos documentation, but in their samples they use ktxTexture_SetImageFromMemory.

Other than that so far it has been clean. I was also wondering if IsSRGB and ktx2ktx2 can be added as well (I could use it to transform to ktx1 and then transcode to rgba8).

Thanks!

Hi! I am working on a texture converter, which extracts texture data from proprietary game files to DDS. However, some of the formats like ETC1, ETC2, ATC, ASTC, PVRTC etc. have to be stored in a KTX/KTX2 container and I would like to use this wrapper.

However, it doesn't support some functions equivalent to DirectXTexNet's ones which I use

It would be great to have some of these:
WriteToMemory/WriteToFile
LoadFromFile
ComputePitch/Slice
BitsPerPixel
IsPremultipliedAlpha

KTX1 writer and loader would be great as well, but I understand this is primarily for KTX2 and Khronos has decided to deprecate version 1 (which unfortunately supports ATC compressed textures natively).

Thanks.
