- If -output_file is specified and there's more than 1 input, it errors out as this would overwrite the output file multiple times
- Tex types cubemap/3D default to tex_array mode
This change implements -resample X Y command line support in addition to
-resample_factor, when a more sophisticated algorithm is needed to
compute the desired image size.
For example, these can be used to round the image to a multiple of 4 or
to a power of 2 for improved compatibility with various graphics APIs.
- Minor fix to basisu_frontend::optimize_selector_codebook() so the new_selector_cluster_indices array is initialized correctly. (The backend doesn't use this array so no harm was being done.)
- Optimized ETC1S encoder (3-4.5x faster)
- Added optional SSE 4.1 support to encoder
- Switched from std::vector to a custom vector in the encoder and transcoder
- Added CppSPMD (SSE only for now)
- UASTC RDO is now more effective, but the command line parameter controlling qualiy has changed (to "lambda")
Encoder is now a library in the "encoder" directory
JavaScript wrappers now expose the entire codec: encoder, transcoder, container independent transcoding, and .basis file information
- Removing BC7 mode 6 support from transcoder (will alway use the much smaller mode 5 tables now)
- Adding BMP support
- Adding -bench mode, for development
- CMakeLists.txt file now compatible with Visual Studio 2019 (MSVC)
- Renaming -no_auto_global_sel_pal to -auto_global_sel_pal, disabling global selector palette usage by default to speed up compression on small images
- Renaming texture format enums
- Fixing uninitialized memory issue in front end - it wouldn't have affected the correctness of the output, or output quality
- Bumping command line tool up to v1.10
- For PVRTC1, we now memset() any extra blocks after the blocks we know will be transcoded into. This is done because in GL there is padding that occurs on textures smaller than 8x8.
- Removing all OpenMP usage and replacing it with a basis C++11 job system.
- Fixing TSVQ class so it can split very long "thin" clusters that before weren't being split. This improves endpoint quantization on videos and complex 2D textures.
- More frontend perf. optimizations.
Tested on OSX, Linux with gcc/clang, and Win using MSVC 2019.
Adding -only_etc1 command line option, because sometimes during unpack you only want the ETC1 images.
