3D congrid without interpolation [message #53449]

Hi,

Is it possible to resize a 3D array in idl without being forced to
interpolate? I am using discrete values to represent different
information and interpolation alters those values. I can't use rebin
since I'd like to change the image size by a non-integral factor.
Thanks.

One question, though. How do I congrid in 2 D on a 3D dataset (how do
I specify which dimension to loop through?)
