Speed up svg -> jpg conversion

[BigNoub]

I'm using Imagemagick 7.0.8-14 on ubuntu 16.04

I'm trying to convert some fairly big (80Mo) svg files to jpg using a simple convert command. The process takes a couple of hours, is there a way to speed that up? I've tried doing the same thing manually with inkscape, it takes a couple of minutes to load the svg file, and a couple of seconds to write it as jpg.

If you know a better option than imagemagick to do this job I'll be happy to use it, as long as it's command-line based.

Edit: I was able to convert under a few seconds using inkscape command line, but if there is a way to speed up the process with Imagemagick too I'm also willing to know it

ImageMagick supports 3 different SVG renderers. One of them is inkscape. To find out which ImageMagick utilizes type `magick -list format` and look for SVG. Which renderer are you using?

Can you post a URL to an SVG file that takes a long time to process? If you do, we'll use it to fix the performance issue.

I made a mistake, I run ImageMagick 6.9.7-4 on Ubuntu 18.04. I can't really update as it's not my server.

I think I can't run

Code: Select all

magick  -list format

with this version? I tried

Code: Select all

convert -list format

but got

Code: Select all

SVG  SVG       rw+   Scalable Vector Graphics (XML 2.9.4)

I don't think that's what you're looking for?

Here is an svg you can use for your tests:

running a simple

Code: Select all

convert in.svg out.jpg

took me 3 hours and 10 minutes.

SVG SVG rw+ Scalable Vector Graphics (XML 2.9.4)

This says your are using XML which uses MSVG for the renderer.

Your file has 359222 path elements. You want to build ImageMagick with one of the delegate SVG renderers, with RSVG or Inkscape. The internal renderer has performance issues with that many path elements.

OK. I couldn't find easily how to specify the renderer in the doc, do I just need to have inkscape installed and in my path?

That should work.

You can find what you have now by

Code: Select all

convert -list format

and look at the end of the line for SVG. It will likely be either XML (for the IM internal MSVG) or RSVG delegate
