Detailed Description

template<typename SUBCLASS>
class TIL_PixelFilterT< SUBCLASS >

Pixel filters should inherit from this using the "curiously-recurring template pattern", so that this class can call the templated filterPlane function in the subclass, e.g.: class TIL_MyPixelFilter : public TIL_PixelFilterT<TIL_MyPixelFilter> { template<int NSRCCOMPONENTS,typename T,int NDSTCOMPONENTS,bool INTERLEAVED> void filterPlane( const TIL_AdaptiveImage &src, PXL_RasterWrapper<T,NDSTCOMPONENTS,INTERLEAVED> dest, int planei, int plane_start_src_component) const; }; The primary advantage of this middle class is to unpack how the raster is stored, so that it can be accessed more efficiently in the pixel filter. Of course, this means that filterPlane will get compiled 45 times, for the 5 data types and 9 packing formats, (including the two 2-to-3 formats).
