(patimg-to-tiff patimg-file tiff-file)
(patimg-to-tiff patimg-file tiff-file) invokes a built-in file format converter which converts the USAPat PATIMG file format as found on the newer USAPat CD-ROM series of the US-PTO to multipage tiff.
The resolutions found in the PATIMG file are preserved using the appropriate tiff tags. Both filenames must be specified as strings. An unspecified value is returned. If any problem occurs during conversion an error is signalled.
Converting is done without decompressing the G3/G4 streams.
