Dxt1Compressor

fastpack_compress::backends::dxt

Struct Dxt1Compressor 

Source 
pub struct Dxt1Compressor;
Expand description

DXT1 / BC1 compressor. No per-pixel alpha. Output is a DDS file.

Uses a fast min/max bounding-box endpoint selector. Quality is suitable for game atlases; it is not the highest-quality iterative cluster-fit approach, but produces valid BC1 blocks with no external dependencies.
