img-ms.lua

A pandoc filter to convert images (and pdfs) in your document to eps so that they work with the pdfroff backend

minimal working example

test.md:

![a single pdf image](./path/to/image.pdf)
![a png image](./path/to/image.png)

pandoc --lua-filter img-eps.lua -t ms -i test.md -o test.pdf

• for some reason pdfs cannot be directly included using pdfroff engine (works in groff 🤷)

• converting to svg first because image magic destroys the quality in pdf to eps conversions but is fine for svg to eps

• tries to save image to pandoc mediabag (not sure why images are saved in base directory as well, this will need fixing)

• set the image title to "fig:..." if caption is non-empty so that the images actually get captions (still not sure how to make them be numbered by pdfroff)
