|
|
The Adaptive Scalable Texture Compression (ASTC) format is
|
|
widely supported by mobile and desktop graphics hardware and
|
|
provides better quality at a given bitrate compared to ETC2.
|
|
|
|
This program supports both compression and decompression in LDR
|
|
and HDR mode and can read various image formats. Run `astcenc
|
|
-help` to see all the options.
