Support multi-page TIFF files
Last modified: 2005-05-25 04:50:34 UTC
A perfect addition to Evince in my opinion would be support for multi-page TIFF files. Rationale: 1. Scanned-in multi-page documents are often stored in multi-image TIFF files. 2. Faxes (yes, those old-fashioned paper transmissions) are almost always stored as multi-image CCITT Group 3 or Group 4 TIFF files. If this is confirmed as a good idea in principle, I would be happy to help with the implementation.
I think the multi-page tiff format would be a great edition to Evince. Is there a different mime-type for multi-page TIFF images from regular TIFF images? Not that this matters too much, but unless we're doing all images it'd be nice to only do muti-page document types. Please hop on irc and the mailing list to start discussion with the other developers.
I've added myself to the mailing list. It seems Evince is already providing support for single-page document types, including TIFF. I'm not sure if this was intentional or not.
Currently, gdk-pixbuf doesn't support image collections. When it does, we should just add support for those (which is much easier than handling tiff files ourselves.) Unfortunately, that isn't going to land until GTK+ 2.8.
Will handling image collections imply the handling of multi-page TIFF files? Image collections means (to me) a directory full of image files. A multi-page TIFF file is a single TIFF file containing multiple pages.
The collection support was actually one image file w/ many images, as tiff, ico, and gif support. However, it might not make it into 2.8 at all.

Committed initial support for this. We could make it much more sophisticated, but lets do that in different bugs.
