Hi,

I was trying to make a class S TIFF that is G4 compressed.

I got this error messages:

Invalid tag "StripByteCounts" (not supported by codec)

Invalid tag "StripOffsets" (not supported by codec)

I saw in www.libtiff.org.support.html these "settings" for Class S tiff:

SamplesPerPixel = 4
PlanarConfiguration = 1, 2
Compression = 1 (none), 5 (LZW)
PhotometricInterpretation = 5 (Separated)
InkSet = 1 (CMYK)
DotRange, InkNames, DotRange, TargetPrinter

 Are the error messages caused by libtiff supporting none,
and LZW compression ONLY for class S TIFF?

Thanks,
Marvin Fresno
