I've been evaluating libtiff for several months and I have a couple of
quick questions:
 
1. When generating a TIFF file and I'm using TIFFWriteScanLine(), is
each call to TIFFWriteScanLine() generating a strip within the TIFF
file?
 
2.I want to extract a CCITT Group 4 image from a TIFF file. If I obtain
the strip offsets using TIFFGetField(), can I concatenate the strips
together to create a valid CCITT Group 4 image file?
 
Thanks for any help
