// .NAME vtkVisItTIFFWriter - write out image data as a TIFF file
// .SECTION Description
// vtkVisItTIFFWriter writes image data as a TIFF data file. Data can be written
// uncompressed or compressed. Several forms of compression are supported
// including packed bits, JPEG, deflation, and LZW. (Note: LZW compression
// is currently under patent in the US and is disabled until the patent
// expires. However, the mechanism for supporting this compression is available
// for those with a valid license or to whom the patent does not apply.)
