I am investigating for our project what file formats support large
images (ie > 2GB). I am not a TIFF expert but noticed that the TIFF
6.0 spec has a field in the Directory Entry structure called "count".
Which is 4 bytes unsigned. This would seem to limit TIFF to an image
size to something less than 4 GB. Is this correct?

For our UNIX machines (HP, SGI, SUN) we are compiling 32 bit applications
and using the transitional API for accessing files > 2GB defined by
the Large File Summit. Most of these are just the same calls with 64
added on (ie open is open64). I noticed that the tiff library does not
use these. Will tiff be modified in the future for this or is 2GB the
current limit of tiff for 32 bit compiles?

I am new to this mail list so if this has been discussed before I am sorry.
I tried to retrieve an archive from the mail list but it never responded.


Thanks,
