The image contents will be the same, as it connects the writer directly to
the reader.  However you can use this program to convert between file
formats, simply by giving a different file extension as the second argument.

First, what type of file did you read, and what format did you save it in?
Second, which program are you using to view the result?

It quite possible that you are trying to display a 16-bit data file, where
the data all lives in the lower end of the spectrum.  Many graphics programs
will not rescale the intensity, so the image may appear black even though
there is non-zero data.

The ImageViewer application (in InsightApplications) can view all supported
formats properly, including handling anisotropic data.
