[Kwintv] Is it possible to port a colour inversion filter from a windows open source project?

[Joe Cotroneo]

Hi,

I've found a windows based open source project DScaler (www.dscaler.org - nice 
app for windows actually, pity they didn't make it cross-platform) that has a 
colour inversion plugin module. It's written as a Microsoft Directshow 
filter, but you may be able to extract the logic from it and implement it in 
kwintv/qtvision.

I've attached a copy of the plugin C source code for your reference.

Hope it helps extend kwintv's functionality, please let me know if it's 
useful.

Cheers,

Joe
