2002.03.19 17:54 "I don't want multiple strips", by Stephen Rasku
The attached program generates a TIFF file that tiffinfo doesn't like. I want all the rows in one strip but it creates multiple strip offsets and when I run tiffinfo on the generated tiff, I get:
tiffcreate.tif: Warning, incorrect count for field "StripOffsets" (10, expecting 1); tag ignored.
