Hi Garry,
Thanks for using PixFC.
The decision to publish our work under the GPL license was not taken lightly.
As far we know, there are no other GPL libraries providing similar capabilities and features to PixFC:
- automatic adjustment of the SSE conversion function to use based on detected CPU features,
- variety of conversion functions, each with advantages and trade-off (fast nearest-neighbour resampling / slower multi-tap average resampling, SSSE3 / SSE2 / scalar)
- balance between conversion speed and image quality accessible and settable through the API.
We believe there is a real value for the open-source community in offering PixFC under the GPL license, and wish for it to remain that way.
Frank
