Request: Add some additional functions and features

[iMrShadow]

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.

Hi, I l should be able to add these:

• BitsPerPixel
• LoadFromFile (add to internalexport.def)
• IsPremultipliedAlpha (add to internalexport.def)
• WriteToFile (add to internalexport.def)
• WriteToMemory (add to internalexport.def)

But

• GetRowPitch seems to be ktx1 only and like you said I'd rather not add ktx1 stuff. From the KTX2 spec: Rows of uncompressed texture images must be tightly packed, equivalent to a GL_UNPACK_ALIGNMENT of 1

Thanks a lot!

I've added the following functions in version1.0.2:

• Ktx2.CreateFromNamedFile
• Ktx2.WriteToNamedFile
• Ktx2.WriteToMemory
• Ktx2.GetPremultipliedAlpha
• Ktx2.Helper.GetDataFormatDescriptor

Let me know if everything works! There are also some other changes to the interface.

Hello! Sorry for the late reply. Thanks for the update, I will try it in the upcoming week or 2, since I have limited time atm. I am closing this issue since the features were added.

I will let you know if there are any issues
