[BUG]: The SVG format is incompatible with PDF files because it requires external sources

[Michallote]

Issue description

test_sample.json

Whenever we use the SVG download option the files are created requiring external sources:

In the content of the SVG file:

<foreignObject width="100%" height="100%" x="0" y="0" externalResourcesRequired="true"> ...
url(&quot;http://localhost:8888/assets/cursor.svg&quot;)

(Yes this was built from the docker container, but issues persist when done from the website.)

Most if not all tools for converting between SVG and PDF warn about improper SVG formats:

$ inkscape -D ATG.svg  -o AircraftTreeGraph.pdf --export-latex
WARNING: unknown type: svg:foreignObject
WARNING: unknown type: svg:foreignObject
** Message: 22:32:29.473: CairoRenderer: empty bounding box.
Failed to save PS/EPS/PDF to: AircraftTreeGraph.pdf

Also tried rsvg-convert -f pdf -o t.pdf ATG.svg but it produces unrenderable PDFs

The size of the SVGs is substantialy larger than it should be...

Media & Screenshots

Operating system

• OS: [e.g. PopOs! 22.04]:

• Browser [e.g. docker, brave]:

• Any other details...

Priority this issue should have

Medium (should be fixed soon)

Is there any update on this? I'm experiencing the same bug.

Or any workarounds while a fix is being worked on?

What I was able to do was to use the print functionality (to PDF) from my browser. (Turning off backgrounds and other ui elements helps) and it at least produced the pdf with rendered text and icons, which was an ok compromise. At least it avoids .png pr .jpeg and was lighter
