How to convert an existing Google Slides / PowerPoint theme to Slideas Markdown Presentation template?

In this tutorial, we are going to see the various aspects of the migration from a template in Powerpoint format (.pptx) to Slideas.

Note: You can also use this technique to convert a Keynote template by exporting it first to Powerpoint (File -> Export to -> Powerpoint)


Finding a theme candidate

For this tutorial, I am going to use the Quickly Theme from Slidescarnival

Slidescarnival provides a wide set of multi purposes themes under the Creative Commons License Attribution 4.0.

This template is an interesting one because it will involves different concepts:

  • Custom fonts
  • Multiple palets
  • Vector images

The original template, let’s try to be as close as possible in our Slideas version.

Required tools

  • lesscss It is a CSS preprocessor that will make our life much easier when writing CSS code.
  • Powerpoint, 1 month trial version: only required to export vector assets.

Bitmap Images

Vector Graphics

Extracting the Vector Shape in EMF format

Converting EMF to SVG

Optimising the SVG
