Description hadmut 2009-12-27 18:47:29 UTC 
Version:           4:4.3.2-0ubuntu1 (using KDE 4.3.2)
Installed from:    Ubuntu Packages

Hi, 

when opening a multi-page tiff, which is generated by most scanners/scanning software (you can construct a multi-tiff from single-tiffs with tiffcp and disassemble with tiffsplit), okular displays only the first page.

Since okular is a document viewer and should support tiff, I'd rather consider this as a bug than as a wish. 

regards

Did you actually install the distro package providing the TIFF backend?
Comment 2 hadmut 2009-12-28 21:49:35 UTC 
That's a pretty good hint, that was the problem. Thanks.  

okular is able to read a tiff even without that package, so it is not obvious that there is something missing. Even installing that package does not help immediately, okular still reads /usr/lib/kde4/okularGenerator_kimgio.so on one of my computers, but then it worked on my other computer where I installed the package before starting okular for the first time. 

Seems as if okular would not recognize the tiff backend without a complete restart of the Desktop.

Ok, closing then.

Or, if you have a 2.6.31 or 2.6.32 Linux kernel, KDE's file change notification system does not cope to its behaviour change. Manually running `kbuildsycoca4 --noincremental` will do the job, in any case.
