## Notes and limitations ## Notes and limitations
* Uses stb_image for image loading. Therefore only supports radiance HDR images, not OpenEXR. * Uses stb_image for image loading. Therefore only supports radiance HDR images, not OpenEXR.
* KTX2 writer probably isn't the most robust, but it works for what I need in my pipeline. * KTX2 writer probably isn't the most robust, but it works for what I need in my pipeline.
* ispc_texcomp doesn't appear to have seperate options for encoding linear BC1, BC3 and BC7 textures. The only difference is the method I use for scaling and the format header.
Therefore the linear textures I output are probably very non-optimal. BC4/BC5/BC6 is probably best for linear data.
* Tested with LDR and HDR single images and cubemaps. May work with 3D textures and arrays, but not tested. * Tested with LDR and HDR single images and cubemaps. May work with 3D textures and arrays, but not tested.
