Judging from the information at Image Pro Express' website: http://www.mediacy.com/ipe.htm I assume that you're referring to 12-bit gray scales. The TIFF import code adheres to the TIFF revision 6 standard: http://partners.adobe.com/asn/developer/PDFS/TN/TIFF6.pdf Only grayscales of 4- and 8-bits per sample are allowed in the standard. Your software must be relying on some vendor-specific extension. -- P.J. Hinton User Interface Programmer paulh at wolfram.com Wolfram Research, Inc.
