LaTeX and PDF export: Incorrect export of SVG images included via `![]()`

[aravindh-krishnamoorthy]

Problem description

Presently, SVG images can be directly included in Jupyter notebooks via the ![SVG file](file.svg) directive. However:

• LaTeX export results in \includegraphics{file.svg} which is unsupported in LaTeX as of now.
• PDF via LaTeX export fails due to XeLaTeX compilation error.

Version Info

nbconvert 7.16.4

How to reproduce

• Open a new Jupyter notebook file.
• Include an SVD via ![SVG file](file.svg) in a Markdown cell.
• Export the resulting notebook to LaTeX or PDF as: jupyter nbconvert --debug <filename> --to latex or jupyter nbconvert --debug <filename> --to pdf

Workaround

• A workaround for LaTeX export, which utilizes the svg package and needs -shell-escape option is provided in LaTeX export: Support SVG image files via the svg LaTeX package #2190.

[aravindh-krishnamoorthy]

Note that an alternative fix is to use the svg2pdf.py preprocessor to "pre-convert" the SVG file included via ![]() into PDF, as it is currently done for image/svg+xml.

IMHO the \includepackage{svg} method is better. However, this is open and up for debate.

I'm not sure if #244 and this are duplicates... cells with MIME type image/svg+xml (which #244 is referring to via plot) are already correctly filtered via svg2pdf preprocessor... whereas this issue is about SVG files included via ![]()...

#244 is definitely about SVGs in markdown cells with ![](....svg). There are other issues around the svg2pdf preprocessor that you might be thinking of.
