Hi,

I am trying to use this to load and save from a filename

Loading: BC7 dds input file from hard drive (with a filename) - output to RGBA raw uncompressed mem stream.

Example: Loadbc7("c:\myfile.dds");

Saving: RGBA raw uncompressed mem stream to BC7 dds output file (a filename - height and width need specifying to the output file) Savebc7("c:\myfile.dds", 512, 1024);

Do you have any working examples of this?

Hi, I would start by checking out Microsoft DDS documentation: https://docs.microsoft.com/en-us/windows/win32/direct3ddds/dx-graphics-dds-pguide

DDS is supported by numerous tools (like AMD Compressonator, Renderdoc, etc.) and libraries (like freeimage).

You can also find several DDS readers/writers on github, for example: https://github.com/Microsoft/DirectXTK/wiki/DDSTextureLoader
