PowerPoint

Overview

You can create PowerPoint presentations using the pptx format. PowerPoint presentations support core presentation features like incremental bullets, 2-column layouts, and speaker notes, and can also be rendered using custom PowerPoint templates.

Creating Slides

In markdown, slides are delineated using headings. For example, here is a simple slide show with two slides (each defined with a level 2 heading (##):

---
title: "Habits"
author: "John Doe"
format: pptx
---

## Getting up

- Turn off alarm
- Get out of bed

## Going to sleep

- Get in bed
- Count sheep

You can also divide slide shows into sections with title slides using a level 1 header (#). For example:

---
title: "Habits"
author: "John Doe"
format: pptx
---

# In the morning

## Getting up

- Turn off alarm
- Get out of bed

## Breakfast

- Eat eggs
- Drink coffee

# In the evening

## Dinner

- Eat spaghetti
- Drink wine

## Going to sleep

- Get in bed
- Count sheep

Finally, you can also delineate slides using horizontal rules (for example, if you have a slide without a title):

---
title: "Habits"
author: "John Doe"
format: pptx
---

- Turn off alarm
- Get out of bed

---

- Get in bed
- Count sheep

The examples above all use level 2 headings for slides and level 1 headings for sections/title slides. You can customize this using the slide-level option (See the Pandoc documentation on structuring the slide show for additional details.

Incremental Lists

By default number and bullet lists within slides are displayed all at once. You can override this globally using the incremental option. For example:

title: "My Presentation"
format:
  pptx:
    incremental: true   

You can also explicitly make any list incremental or non-incremental by surrounding it in a div with an explicit class that determines the mode. To make a list incremental do this:

::: {.incremental}

- Eat spaghetti
- Drink wine

:::

To make a list non-incremental do this:

::: {.nonincremental}

- Eat spaghetti
- Drink wine

:::

Multiple Columns

To put material in side by side columns, you can use a native div container with class .columns, containing two or more div containers with class .column and a width attribute:

:::: {.columns}

::: {.column width="40%"}
contents...
:::

::: {.column width="60%"}
contents...
:::

::::

Speaker Notes

You can add speaker notes to a slide using a div with class .notes. For example:

## Slide with speaker notes

Slide content

::: {.notes}
Speaker notes go here.
:::

PowerPoint Templates

By default PowerPoint output uses a fairly plain looking template. You can customize what template is used via the reference-doc option. For example:

---
title: "Presentation"
format:
  pptx:
    reference-doc: template.pptx
---

Nearly all templates included with recent versions of PowerPoint (either with .pptx or .potx extension) are known to work, as are most templates derived from these.

The specific requirement is that the template should contain layouts with the following names (as seen within PowerPoint, click on Layout under the Home menu to check):

  • Title Slide
  • Title and Content
  • Section Header
  • Two Content
  • Comparison
  • Content with Caption
  • Blank

For each name, the first layout found with that name will be used. If no layout is found with one of the names, Pandoc will output a warning and use the layout with that name from the default reference-doc instead.

Creating a Template

To create a template from scratch, start with the default PowerPoint template as follows:

quarto pandoc -o template.pptx --print-default-data-file reference.pptx 

Then edit the template.pptx file within PowerPoint as desired, and use it as the value for reference-doc (as shown above) when rendering your slides:

Slide Layouts

When creating slides, the pptx writer chooses from a number of pre-defined layouts, based on the content of the slide:

Title Slide

This layout is used for the initial slide, which is generated and filled from the metadata fields date, author, and title, if they are present.

Section Header

This layout is used for what pandoc calls “title slides”, i.e. slides which start with a header which is above the slide level in the hierarchy.

Two Content

This layout is used for two-column slides, i.e. slides containing a div with class columns which contains at least two divs with class column.

Comparison

This layout is used instead of “Two Content” for any two-column slides in which at least one column contains text followed by non-text (e.g. an image or a table).

Content with Caption

This layout is used for any non-two-column slides which contain text followed by non-text (e.g. an image or a table).

Blank

This layout is used for any slides which only contain blank content, e.g. a slide containing only speaker notes, or a slide containing only a non-breaking space.

Title and Content

This layout is used for all slides which do not match the criteria for another layout.

These layouts are chosen from the default pptx reference doc included with Pandoc, unless an alternative reference doc is specified using reference-doc.

Background Images

To provide a common background image for multiple slides in a PowerPoint presentation, include the background image within the relevant slide layouts of a custom PowerPoint template (see Creating a Template for details on creating templates).

To add a background image to an individual slide, add the background-image attribute to the slide’s heading. For example:

## Slide Title {background-image="background.png"}

Note that this also works even if you don’t have slide heading text. For example:

## {background-image="background.png"}

For background images, only the “stretch” mode is supported, and the background image is centred around the slide in the image’s larger axis, matching the observed default behaviour of PowerPoint.
