The 3.6 release contains another round of performance optimizations. There are no interface changes in this release, but in general the API is not designed to be binary compatible across versions. We always recommend rebuilding your client-side code using the updated astcenc.h header.

Change log

General:

  • Feature: Compressor configurations no longer require the SELF_DECOMPRESS_ONLY flag to use defragmented data tables. Tables are always sorted to store active data table entries at the start of the list, with inactive entries stores at the end. If the SELF_DECOMPRESS_ONLY flag is specified the inactive entries are not created, reducing context creation time and memory footprint.
  • Feature: Image quality for 4x4 -fastest compression has been improved.
  • Optimization: Decimation modes are reliably excluded from processing when they are only partially selected in the compressor configuration (e.g. if used for single plane, but not dual plane modes). This is a significant performance optimization for all quality levels.
  • Optimization: Fast-path block load function variant added for 2D LDR images with no swizzle. This is a moderate performance optimization for the -fast and -fastest quality levels.
