Description Niko Mirthes 2005-12-18 17:39:30 EST
From Bugzilla Helper:
User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.7.12) Gecko/20050922 Fedora/1.0.7-1.1.fc4 Firefox/1.0.7

Description of problem:
KDE should be generating thumbnails when browsing a folder containing files in the SVG image format. This worked with the previous KDE 3.4.2 packages and it works with my personal build. There should also be a ksvg plugin that allows viewing SVG's embedded in konqueror. Both features are missing with the recent release of KDE 3.5.0 to updates-released. Looking over the relevant patches and .specs (kdelibs and kdegraphics) I can't see where this has been intentionally disabled. Can anyone shed any light on this?

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
1. Browse to a directory conatining SVG images with konqueror
2. On the menubar, go to View -> Preview and look for an entry for the SVG format
3. Note the entry is missing

Actual Results:  No previews are shown, nor is the ksvg plugin available when looking at the svg mimetype settings found on konqueror's File Associations page.

Expected Results:  Konqueror should have the SVG Preview option available as well as the ksvg plugin.

This problem is also present in Rawhide.  Instead of appropriate thumbnails, a
thumbnail of the plaintext XML is shown.

This is a problem when adding / selecting desktop backgrounds too (although the
desktop does display correctly).
Comment 3 Niko Mirthes 2005-12-22 20:28:23 EST
I finally realized why this is happening. Seems ksvg (kdegraphics) requires
lcms/lcms-devel, which is available from extras. Saying ./configure in
kdegraphics without lcms-devel installed results in the following message:

Some of the libraries required for KSVG are missing or too old,
therefore KSVG will not be compiled.

If you want to compile KSVG you should install:
* lcms 1.09 or newer (http://www.littlecms.com/)

I've rebuilt kdegraphics with lcms-devel installed and svg previews and the ksvg
konqueror plugin are both available again.

Can packages from base require packages from extras? I've noticed koffice-krita
and koffice-suite both complain if i try to remove lcms.
Comment 4 Bill Crawford 2005-12-23 16:35:31 EST
lcms shouldn't be in Extras, then.
Comment 5 Niko Mirthes 2006-01-09 23:54:31 EST
Can anyone comment on the likelihood of bringing lcms into base? 
Comment 6 Patrick Barnes 2006-01-10 17:04:48 EST
lcms has been pulled into Core for Mono.
Comment 7 Niko Mirthes 2006-01-19 12:47:49 EST
That's great news. Is there a process for moving something from extras to 
core/base? I'd like to see this happen for FC4 as well. 
Comment 8 Ngo Than 2006-02-07 06:35:10 EST
lcms has been pulled into Core now, adn this problem has been fixed in rawhide.

For FC4, it cannot be built with ksvg support because of lacking lcms library.
