The fastest way to test PixFC and/or include it in your application is to:
Instead of downloading the pre-built binaries, you can also download the source code and build PixFC yourself (much longer).
Head to the Downloads tab for a list of latest stable packages, and pick the binary package which matches your platform. If your OS supports 64-bit, make sure you grab a 64-bit binary package !
After unpacking the archive, you can run the time_conversions app to see how fast PixFC performs on you platform. You can compare your results with these. Please take some time to submit your results on the mailing list, along with details of your platform (OS version, CPU name & model).
Assuming you unpacked the PixFC archive in pixfc/, either :
Next, #include "pixfc-sse.h" where appropriate (so you can call PixFC functions). The use-case is then pretty simple:
Take a look at pixfc/example.c for a concrete example. The main header file (pixfc-sse.h) is also a good source of information.
Last, link the PixFC static library (pixfc/libpixfc-sse.a on Mac & Linux, pixfc/pixfc-sse.lib on Windows) to your application. On Linux, also link your application against librt by passing -lrt to the linker. That's it !.
