1998.03.17 13:45 "Strip offsets in TIFF6", by Thad Humphries

<x-rich>When I call 


<paraindent><param>right,left</param>uint32		  strip_offset;

TIFFGetField( tif, TIFFTAG_STRIPOFFSETS, &strip_offset );

</paraindent>

with a file of compression TIFF6, I'm getting what I think is bad data.
 In a hex editor, I can see that the StripOffset tag (0x111) is long
and has a value of 0x473 in all files I have.  But from libtiff v3.4,
I'm getting far different data and different data from different TIFF6
files event though each file actually has the 0x473 value.


I know libtiff.a doesn't do TIFF6 but I have ways to deal with the JPEG
in the images I have to work against.  But I need to be able to
reliably check this tag.
