Shrink text in pptx presentation

[aldotapia]

Hi,

I'm rendering a pptx presentation and the text isn't compressing in text blocks. In my template I have shrink text on overflow activated. Also, I'm using a CSS style for reducing the font size and it isn't working (font-size: 0.5em;)

I'm using RStudio 2022.02.3 for rendering the presentation.

Any hint about this?

Thanks @aldotapia , I would have the same question - even just setting the font size manually on a specific slide in Quarto for pptx would be helpful as a first workaround

Powerpoint styling is possible in the limitation of what is possible in Pandoc. We mentions the template feature in https://quarto.org/docs/presentations/powerpoint.html#powerpoint-templates which is directly based on Pandoc supports: https://pandoc.org/MANUAL.html#option--reference-doc

Though it remains quite limited because Custom Styles is not supported by Pandoc

Also, I'm using a CSS style for reducing the font size and it isn't working (font-size: 0.5em;)

CSS won't work with PPTX. And font-size is not among the option available for PPTX format (https://quarto.org/docs/reference/formats/presentations/pptx.html)

So currently Powerpoint features is limited by Pandoc capabilities.

Thanks @cderv that is good to know! Is there a Pandoc repository where one could try to contribute or make a feature request for a font size option?

The GitHub repository: https://github.com/jgm/pandoc
Although as for docx, pptx follows the same principle, which is to define a reference document with all the styling you want.

You get the link of the repo above by @mcanouil. Though, seeing his answer, I may have been not clear enough before.

PPTX is customizable by a reference doc like DOCX. However, custom styling using Divs and Spans is only working for DOCX. so you can customize some default layout, but you won't be able to apply custom styling on individual content.
In docx you could.
