The old D3DX for Direct3D 9 library implemented a codec for .hdr (aka RGBE).

Currently the only built-in HDR format supported by WIC is HDPhoto (aka JPEG-XR). As such, there's currently few choices for a source format for BC6H textures.

  • LoadFromHDRMemory
  • LoadFromHDRFile
  • SaveToHDRMemory
  • SaveToHDRFile

This would include the 32-bit_rle_rgbe and 32-bit_rle_xyze encodings for lossless, rle (aka 'old format', and adaptive rle (aka 'new format').

D3DX9 would load 32-bit_rle_xyze color-space data, but didn't convert it to RGB. We will do the same thing here.
