Hi,

I'm looking into Gimp as a viable scripting solution for a project however most of the scripting references I'm finding are either sparse or dated.

I was wonder if there was a way to utilize Gimp's scripting system to convert an SVG to a PNG?

The best resource I've found is here however, attempts to run this on my machine are failing using GIMP 2.1.0.

http://www.jasonhardin.com/programming/2012/08/23/Gimp-svg-to-png-script/#disqus_thread

The script I'm running: gimp -i --batch='(svg-to-raster "src.svg" "dst.png" 72 0 0)' --batch='(gimp-quit
0)'

Unfortunately it throws the following error: batch command experienced an execution error: Error: eval: unbound variable: file-svg

I'm using MacOS to write the script, but the target platform is Windows.

I understand there are many other tools for performing this conversion (and I'm leveraging these tools in other parts of code) but I was hoping to write this as a fallback for this particular system.

Best regards,

-Tres

Apologies, typo:
Error: eval: unbound variable: file-svg

Should have been: Error: eval: unbound variable: *svg-to-raster *

Hmm... I'm not sure why the scripting system is continuously dismissed as a viable solution. Is your answer that it's not viable. Requoting:

Tres,

Several perhaps better options are tools intended for command line use:

https://www.imagemagick.org/script/download.php

Or, for considerably more sophisticated image work (with correspondingly more detailed and opaque documentation) G'MIC (which also has a builtin tool for use inside GIMP usually packaged with GIMP):

https://gmic.eu/download.shtml

Both of these tools can be scripted.

I'm confused, I'm attempting to use the gimp command line, is it no longer supported? Why am I being told to use other tools still?

This is a specific attempt to use Gimp for a task. No additional software installed. If Gimp ships with a usable version of python in a reliable location, I'd be happy to leverage that, but the question is in regards to a target system with only Gimp installed, assuming it doesn't have Inkscape, ImageMagick Python or Perl.

I'm asking how to use the gimp command line only.

Yes, from python, perl or scheme (script-fu).

there's also batch mode add-ons such as phatch.

You might prefer to use Inkscape for this one - it can do this in the command-line.

Hoping you mean 2.10.18

I'm using MacOS to write the script, but the target platform is Windows.

We are a release behind n the Mac because we don't have a Mac maintainer right now.

For the error you're getting try changing file-svg to file-svg-save maybe.

Liam,

After re-reading your post, is it safe to assume my original question was written in scheme/script-fu?

If so, can someone direct me how to get a list of scheme commands that can be executed from a vanilla gimp install?

Are my examples written in Carrette’s SIOD instead of TinyScheme? Was the svg-to-raster command removed in a certain version (or perhaps not distributed with the macOS build?).

This seems like it's a fairly simple script, but the fact that it doesn't work leads me to believe something has changed since the linked article was written.

Michael,

You're completely right, the web archive of that original post has it for download. Here's the web archive article, which specifically mentions downloading svg-to-raster.scm.

https://web.archive.org/web/20140214102644/http://porpoisehead.net/mysw/index.php?pgid=gimp_svg

Fortunately, web archive had a copy of the scheme source. I've re-hosted it here: https://gist.github.com/tresf/c06aac6ceb51b86f328c3655fb503efe

I'll continue down this path and share my progress. Thanks kindly!

What you found is just the command line being used to run a custom script someone wrote - I assume this was available from one of the now-defunct links in the message you linked to.

In short: what you have found and posted is not a complete script, not by far.

In principle, the actual script was likely similar to the examples in https://www.gimp.org/tutorials/Basic_Batch/ - with different parameters, though, as it only really needs to open a file and export it with a different file name.

A one-liner using Gimp and no other tools:

./gimp -i -b '(let* ((image (car (file-svg-load RUN-NONINTERACTIVE *"input.svg"* "" *72* (- 0 *400*) (- 0 *600*) 0))) (drawable (car (gimp-image-get-active-layer image)))) (plug-in-autocrop RUN-NONINTERACTIVE image drawable) (gimp-file-save RUN-NONINTERACTIVE image drawable *"output.png"* *"output.png"*) (gimp-image-delete image))' -b '(gimp-quit 0)'

Probably the script you were running, the one you didn't includeand got from Web archive, was in Scheme, yes.

It's a text file, and the likely error from the message is that it calls file-png to export, and not file-png-save.

If so, can someone direct me how to get a list of scheme commands that can
be executed from a vanilla gimp install?

Are there any known caveats to running these command on Windows?

I'm testing the above with CMD and no matter how I run it, it pops up a dialog asking me what resolution to import the file at, I can't get it to run non-interactively.

- I've tried escaping the asterisks - I've tried gimp-2.10.exe
- I've tried gimp-console-2.10.exe - I've tried swapping single quotes and double-quotes

It works on macOS Gimp 2.10.14 but does not work on Windows using Gimp 2.10.18.

When I try to run the first portion interactively, I receive the following errors:

- Opening *'C:\Users\owner\Desktop\((image'* failed: Error opening file C:\Users\owner\Desktop\((image: No such file or directory - Opening *'C:\Users\owner\Desktop\(car'* failed: Error opening file C:\Users\owner\Desktop\(car: No such file or directory - Opening *'C:\Users\owner\Desktop\(file-svg-load'* failed: Error opening file C:\Users\owner\Desktop\(file-svg-load: No such file or directory

I've tried using PowerShell and receive very similar results. What am I doing wrong?

Ok, I got it. Had to remove all single quotes and use backslash instead of uptick to escape the double-quotes.

Here's a working Windows example: https://gist.github.com/tresf/1bd76fc8cd4a4def215c68cab990dfb1
