I had similar needs, and have written an enhancement for the tiffset utility that allows you to do this. I have uploaded the corresponding patch to bugzilla. You should be able to download it from there if desired and rebuild tiffset. Hopefully this will soon be included in a standard logTIFF release.


What I need to do is to read (multilayered) Photoshop TIFF images in an anther application for which I've written a layered TIFF reader.

Considering that the layered TIFF is generated by a Photoshop user *within* Photoshop, do you still think your library or LibTIFF can help "smuggle" private tags into the Photoshop file? (I need Photoshop to save the private tags with the multilayered TIFF).

I've already written an application that reads (multilayered)

Currently, I'm using the layer names to distinguish them from each other, but there's nothing to stop a user giving 2 layers the same name...

Left field suggestion, can you use the IPTC or other Photoshop metadata instead?
