Figure captions not inheriting master slide font settings

[yonisidi]

Description

I have a figure in a slide that has a caption.

When it renders the caption it does not use the font defined in the master slide template (screen grab of Two Column Layout below). Do I need to add something to layout for the caption to have a place to go? currently it looks like the caption object is creating as a side-effect.

Could you share a small self-contained "working" (reproducible) example to work with, i.e., a complete Quarto document or a Git repository? The goal is to make it as easy as possible for us to recreate your problem so that we can fix it: please help us help you! Thanks.

Did you follow the below documentations to create your template?

• https://quarto.org/docs/output-formats/ms-word-templates.html (this is for Word but the same principles apply and this page has screenshots)
• https://quarto.org/docs/presentations/powerpoint.html#powerpoint-templates
• https://pandoc.org/MANUAL.html#option--reference-doc

---

You can share a self-contained "working" (reproducible) Quarto document using the following syntax, i.e., using more backticks than you have in your document (usually four ````).
See https://quarto.org/bug-reports.html#small-is-beautiful-aim-for-a-single-document-with-10-lines.

If you have multiple files (and if it is absolutely required to have multiple files), please share as a Git repository.

Additionally, and if not already given, please share the output of quarto check within a code blocks (i.e., using three backticks ```txt), see https://quarto.org/bug-reports.html#check.

I believe there is another issue here, as caption will not show in output when #fig- prefixed label is used.

captions come out ok for figures

The font isn't inherited correctly

In the case of the expected font, I would think that if the master slide is set to font XXX, then any object created should inherit it and not the default powerpoint font (not even talking about the font size).

I do think this is a Pandoc's limitation. I don't know how they create the caption but directly using pandoc CLI with a reference document gives me the same output.

You should try to convert a .md doc with an image & caption, pass your reference doc and see about the caption font. It could be a Pandoc issue

[yonisidi]

@cderv you are right, direct to pandoc creates same problem:

pandoc test2.md -o test2.pptx --reference-doc=_extensions/yonisidi/cmei/resources/cmei_template.pptx

[cderv]

Unfortunately, this means we need Pandoc to do better...

I opened an issue on the pandoc repo jgm/pandoc#9896

[yonisidi]

looks like this is an issue bouncing around in SO too

Same issue with tables

The font settings of the table contents and caption of the table are not inherited from the master slide, you can see the difference between the font in the left column and the font in the right column
