1994.12.02 23:51 "Re: Directory Access Time in TIFF Files", by Victor C Zandy

Construct a private tag that has a table of contents of all the images in each file and use that to locate each IFD. I believe the latest code on sgi.com includes a call to let you set the current directory given a file offset; this was added for the SubIFD support.

Yes, the TIFFSetSubDirectory() routine does exactly this. It would be very helpful, but I don't see a way for a client to get the directory offset in the first place. Is there?

If not, I have written a selector for it. Would you (Sam) be willing to add it to future releases of libtiff?

Thanks,
Vic
