This package may be used as an unrestricted substitute for wip/libtxc_dxtn.

S2TC provides a subset of a wellknown texture compression scheme.
|
|
This package provides the library libtxc_dxtn which can be used by
|
|
grahics/MesaLib.
|
|
|
|
S2TC's format specification is very easy to implement, so it is
|
|
not hard to make a working compressor or decompressor for it. It
|
|
is based on Color Cell Compression[1] from 1986, and decoding is
|
|
done entirely using the methods from there. Encoding is done using
|
|
a search and refinement method that is derived from the methods
|
|
described in that paper.
|
|
|
|
The compressor and decompressor here are licensed under a license
|
|
that gives you all freedoms you will ever need (namely, the MIT
|
|
license). In particular, the MIT license allows you to use, copy,
|
|
modify, merge, publish, distribute, sublicense or sell the software,
|
|
provided you keep copyright notices intact.
