Description

I'm trying to convert generated svgs into pngs. These Inkscape files using svg 1.2's feature flowRoot in order to specify an area where text will wrap. Since the svg content is produced on the fly I cannot know where to put newlines and must use flowroot. ImageMagick doesn't use svg 1.2 so the flowRoots don't appear in the png result.

I am attempting to use Inkscape to convert svgs to pngs by using the Inkscape delegate defined in the comment of C:\Program Files\ImageMagick-7.1.0-Q16-HDRI\delegates.xml. I believe exporting using Inkscape will fix my invisible flowroot issue, as flowroots are visible when the svg is viewed in Inkscape.

When I attempt to load an image using Wand's Image(filename=filepath), I get:

 FailedToExecuteCommand `"inkscape" "C:/Users/User/AppData/Local/Temp/magick-4xz3QdjPkX3UYiyBRMu8nYBqCuTw8_Cq" --export-filename="C:/Users/User/AppData/Local/Temp/magick-zW7J8OFWBFi58L9b_-Tcv7w34wNWy2Kl.png" --export-dpi="96" --export-background="rgb(100%,100%,100%)" --export-background-opacity="1" > "C:/Users/User/AppData/Local/Temp/magick-998jW10fOSoGe0W-fvwNGDVDNPdnXfQi" 2>&1

Oddly, Image(svgFilePath) isn't even at the svg->png step. Why would my svg:decode delegate be used when im not exporting to png?

How can I get more information as to why it failed and what might be causing the error?

Probably related, I've attempted to add Inkscape to my path to run the command myself, but the bin folder for Inkscape includes a python exe which overwrites my Python installation back to Python 2. I need to use my python to run this whole shebangy so I cannot have it in my path. The Inkscape installer does not include a "Do you want to add this to your path?" dialog.

Steps to Reproduce

• Install Inkscape 1.2.2 (732a01da63, 2022-12-09)
• Install ImageMagick-7.1.0-58-Q16-HDRI-x64-dll.exe
• Install GTK for Windows (This might be unrelated)
• Add GTK bin to path
• Change C:\Program Files\ImageMagick-7.1.0-Q16-HDRI\delegates.xml to have

<delegate decode="svg" command="&quot;rsvg-convert&quot; -o &quot;%o&quot; &quot;%i&quot;"/>
  <!-- Remove the extra space in - -export in the line below when you want to use inkscape and change export-filename to export-png for inkscape < 1.0 -->
  <delegate decode="svg:decode" stealth="True" command="&quot;inkscape&quot; &quot;%s&quot; --export-filename=&quot;%s&quot; --export-dpi=&quot;%s&quot; --export-background=&quot;%s&quot; --export-background-opacity=&quot;%s&quot; &gt; &quot;%s&quot; 2&gt;&amp;1"/>

• pip install wand
• In a python file, run the following using the attached image.

        svgImage = Image(filename=filepath)    
        svgImage.save(filename=outputFilepath)
        svgImage.close()

• Receive the error below:

Why are you using version 6.7.7-6 and saying you installed ImageMagick-7.1.0-58-Q16-HDRI-x64-dll.exe?
