    sample() on edges - wrap?

      Just wondering if there's a way to get sample(), when sampling just beyond an edge pixel, to interpolate between that edge pixel and the edge pixel on the other side of the image, rather than with a transparent pixel ("wrap" the image).

      Basically, I'm writing a simple linear-to-polar coordinates filter, and I can see the effects of the interpolation with the transparent pixel at around -pi to pi because those are the edges of the transformed image.
