Description Rainer Bielefeld Retired 2011-11-08 10:50:39 UTC
Currently no PNG previews will be created for SVG pictures. I uploaded a.m. document and <https://wiki.documentfoundation.org/File:BugsNeedingReview.svg>. In both pages no picture will be shown, but message "Fehler beim Erstellen des Vorschaubildes: /var/www/sites/wiki.documentfoundation.org//bin/ulimit4.sh: line 4: convert: command not found".

Thanks for the hint! Installed ImageMagick, tried to set wgMaxShellMemory, but then the script grabs all available memory. Can you ping Manuel Schneider <manuel.schneider@wikimedia.ch>, our wiki expert, directly?

We need some results here, what's the problem?
Comment 3 Christian Lohmaier 2011-12-06 07:38:50 UTC
convert is not able to convert the svg - it just needs too much memory. So there must be something special about this and a few other files.

Looking at them, they have a ridiculously large canvas size. 28000x14000 pixel for example (the LO-qa with the meter-icon). A png of the size of 8meters x 4meters.. No wonder why convert cannot deal with it.

The one mentioned in the initial comment has a canvas/document size of
29700,00 x 21000,00 pixel - those values ars suspicious, as 297mm x 210mm would be the size of A4 paper.

The BugsNeedingReview.svg is ~ 8m x 6m instead of the intended ~30cm x 21cm.

So this one is "wontfix". You will need to recreate the svg with a more suitable canvas size.

... what recommends not to use LibO ;-)

May be you can help with "Bug 43060 - DRAW EXPORT results in HUGE SVG Picture Size"? I did not fine anything concerning unit for those dimensions.
