"Could not determine PDF size"

[sjackman]

I'm rendering Markdown to DOCX, and I'm seeing the error could not determine PDF size. Both Mac OS and ImageMagick report that the PDF size is 522 x 504 pt (7.25 x 7 in). I can send you the PDF, if it's helpful. @github issues unfortunately don't allow uploading PDF.

❯❯❯ make docx
pandoc --filter=pandoc-citeproc -o white-spruce-organelles.docx white-spruce-organelles.md
pandoc: Could not determine image size in `figure/mt-gene-order.pdf': could not determine PDF size

Please put the PDF somewhere and link to it so we can have a look.

I noticed this in Text.Pandoc.ImageSize:

   Just Pdf  -> Left "could not determine PDF size" -- TODO

which accounts for what you're seeing. Just need to write
the code for extracting image size from the PDF. Or maybe
the JuicyPixels library will help with that.

For now I've converted the PDF to PNG.

brew install imagemagick
convert -units PixelsPerInch -density 600 fig.pdf fig.png

Hi, just wanted to follow-up on this. I'm having the same symptom as in #2381 -- markdown-included PDFs render fine in PDF output, but docx output shows "Read-error". Since it's been a few years since any comments on this thread I just wanted to see if there are any alternative recommendations at this point, or if it's still just pending "code for extracting image size from the PDF".

This issue was actually fixed by eeafb3f

@nsheff It's not possible to include PDFs in docx files.

It is possible though:

Word for Mac can display PDF figures in docx produced by pandoc (2.2.1), albeit the size (or at least the aspect ratio) appears wrong. Word for Windows doesn't display those figures.

Attempting to output to ODT produces this warning ([WARNING] Could not determine image size for '...pdf': could not determine PDF size).

@bogdanni, interesting! If you could post a minimal docx file that embeds a PDF and works cross-platform (also for a bit older Word versions) to #2061, that would be great. (Or even better, also the XML snippet responsible...)

[bogdanni]

The bad news is that Word for both Mac and Windows convert the PDF on insert into EMF. The attached is made with Word for Mac 16.15.

Ah, so it's not actually embedding the PDF. I guess image conversion is currently out of scope for pandoc...
