Frank, all:

Just wondering if there are any plans to move to using 64 bit offsets for large file support greater than four gig?

There has been occational discussion on the issue, but it is hard to see how it could be done without impacting backward compatbility. That is, 64bit TIFF would essentially be a new format that traditional TIFF readers wouldn't be able to touch.

The short answer is that there is no current plan to implement support for files larger than 4GB.

Wasn't there a suggestion that the TIFF/IT format could be used, as it allow tiling of multiple TIFF files? I'm not very familiar either with TIFF/IT or tifflib. Presumably this would NOT be a quick fix, as TIFFLIB doesn't handle TIFF/IT and neither do most existing TIFF-based applications.

Is TIFF/IT still alive? I don't hear much about it lately.
