This sounds like an incompatibility between the image parameters
(number of bits, bits allocated, high bit, etc) and the actual data
you are passing in. If you can show us how you are setting these
values and then print the type of the data array you are passing
things might become clear. I suspect IDL is truncating the data based
on these values.
