Hi,

I use Inkscape via CLI with the PHP system command to create unique SVGs within a headless GUI. I use PHP to create a base SVG with unique text/variables (like a mail-merge), and then use Inkscape CLI verbs to complete actions and save out the "rendered" SVG.

Here is the issue. It is slow. 3 seconds per render. My entire database of data for the unique 30,000 SVGs to be created takes 24+ hours to render. Each SVG file creation requires an Inkscape to be launched and closed. This appears to only happen on 1 CPU core. I have 8 cores.

Can I launch 8 Inkscapes at the same time using pthreads? Or will Inkscape freak out?

Any help is much appreciated.

Have you tried using the shell mode?

Wow. I did not realize this existed. Very cool.

Hmmm. Curious. I have never done anything like this before.

If I run the following within PHP it will execute the shell and then just hang, as it waits for further instructions.

system("inkscape --shell");

How do I keep sending it verb commands in sequence from my PHP script?



Any help is very much appreciated.

Hmm. I don't think Inkscape --shell can accept verb commands, as the verb commands require a GUI.

Have you tried it? The man page doesn't say anything about the shell mode not working with gui, and indeed, it works.
