* Iterative cluster fit is now considered to be a new compression mode
|
|
* The core cluster fit is now 4x faster using contributions by Ignacio
|
|
Castano from NVIDIA

|
* The single colour lookup table has been halved by exploiting symmetry
|
|
|
|
1.9
|
|
* Added contributed SSE1 truncate implementation
|
|
* Changed use of SQUISH_USE_SSE to be 1 for SSE and 2 for SSE2 instructions
|
|
* Cluster fit is now iterative to further reduce image error
|
|
|
|
1.8
|
|
* Switched from using floor to trunc for much better SSE performance (again)
|
|
* Xcode build now expects libpng in /usr/local for extra/squishpng
|
|
|
|
1.7
|
|
* Fixed floating-point equality issue in clusterfit sort (x86 affected only)
|
|
* Implemented proper SSE(2) floor function for 50% speedup on SSE builds
|
|
* The range fit implementation now uses the correct colour metric
|
|
|
|
1.6

|
* Fixed bug in CompressImage where masked pixels were not skipped over
|
|
* DXT3 and DXT5 alpha compression now properly use the mask to ignore pixels
|
|
* Fixed major DXT1 bug that can generate unexpected transparent pixels
|
|
|
|
1.5

|
* Added CompressMasked function to handle incomplete DXT blocks more cleanly
|
|
* Added kWeightColourByAlpha flag for better quality images when alpha blending

|
* Added provably optimal single colour compressor
|
|
* Added extra/squishgen.cpp that generates single colour lookup tables
|
|

|
* Fixed a DXT1 colour output bug
|
|
* Changed argument order for Decompress function to match Compress
|
|
* Added GetStorageRequirements function
|
|
* Added CompressImage function
|
|
* Added DecompressImage function
