# Handout-mode in LaTeX slides

Whether it is lecture slides or presentations, you often wants to distribute pdf-versions of your beamertex file. If you are using overlay to blockwise show text or blockwise highlighting parts of tables (see here and here for ways to color parts of tables with overlay), it makes little sense to distribute the pdf versions where one and the same slide is repeated with each overlay step. Luckily, there is a extremely simple solution

# Beamertex 16:9 aspect ratio

With an increasing number of beamers supporting 16:9 aspect ratio of your presentation slides, it is fairly easy to implement this in beamertex. Simply add “`aspectratio=169`” to the options in document class command in the first line of your latex file:

`\documentclass[aspectratio=169]{beamer} `

That’s it!

# Include entire PDF files in your LaTeX document

I described already earlier how to use images in pdf format in your LaTeX document, e.g. if you want to include a screenshot of a Table of a paper in pdf format in your slides (which results in much better quality than using jpg or similar formats).

But what if you want to include complete pages of a document or even complete pdf documents? I have used the latter for example as a reliable tool to append pdf documents, such as papers.
