I hope it is not but rather a feature of the program you use.

I used Windows XP for that to find out what elements of PostScript
are used by IDL. The IDL plotting devices (PS is one of them) does
not depend on the operating system, so I'm pretty sure that if
IDL translates TV into the PS image operator (using Windows XP)
it will do so using OSX.

I tried a couple of PS interpreters to find how they in turn handle
the image operator and all of them filled the rectangles specified
by image with constant color. No interpolation occured.

So you should contact the author/service team/who ever of the program
that causes the image operator to interpolate.
