Hi,

I'm trying to thumbnail SVG to PNG for my wiki, and the thumbnail command seems to be breaking the process; the SVG will not upscale. This is with version 6.6.9-6. More details can be found on the support board here and at MediaWiki Users.

Assume you want a high quality thumbnail of Pikachu_-_Dream_World @ 100x100 pixels. This works for us with ImageMagick 6.6.9-9, the current release:

• convert -density 400 Pikachu_-_Dream_World.svg -thumbnail 100x100 Pikachu_-_Dream_World.png

For optimal results, make sure you have RSVG support. Type

• identify -list format

and hopefully you get

• SVG SVG rw+ Scalable Vector Graphics (RSVG 2.32.1)

If you instead have built-in SVG support, add the RSVG and RSVG development RPM's to your system. Now build and install ImageMagick from source.

That worked! I ended up putting the density to the width amount to keep ideal pixel density.
