If you want to annotate screenshots or other figures in your LaTeX papers, the following small tool might help:
LaTeX Overlay Generator (Demo)
Source code on GitHub
It creates the whole source code needed to create annotated figures as shown on the right directly in LaTeX without modifying the underlying image file. You can also use the tool to embed any text on top of your figure (e.g., use
\cite commands on top of an image). Give it a try! 🙂
There are still a lot of bugs, because it was a quick and dirty hackday project. You can find the source code on GitHub.
