Inspiration

I needed convert PowerPoint into pdf or pdf. I found the following projects:

• node-ppt2pdf (not on npm)
• ppt2png (npm)

Both require unoconv and LibreOffice (or OpenOffice) however it didn't work with the latest version of Libreoffice. I assume it was because of a older version of unoconv/libreoffice. However, the latest version of libreoffice can convert to pdf on the command-line, please see below.

libreoffice --headless \
--invisible \
--convert-to pdf \
--outdir <outputDir> \
inputPath
