Using what I remember from looking at Magick Core recentally,
applications that use Interpolation makes calls to the C function
InterpolatePixelColor()
EG: from the fx.c MagickCore source...
pixel=InterpolatePixelColor(image,image_view,image->interpolate,x,y,
exception);
The reason is that to get the right interpolated color the function may
need to lookup not just the pixels around the point (in 2 dimensions),
but also for the ones beyond that (for 'bicubic').
Remember this is for looking up floating point pixel coordinates, not
direct pixel colors (integer position lookup), though it can be used for
that too, it's just slower and with less speed improvements
that MagickGetImagePixels provide for batch processing.
It may take a bit a time before InterpolatePixelColor makes it into
the various API's. CommandLine is often used as 'bleeding edge'
testing of the various new features of MagickCore.
