The Advent of Void: Day 24: gromit-mpx

Have you ever wanted to doodle on a screenshot? Ever? Just a single underline, or an arrow, or something to help point out something about a screenshot? Or maybe during a presentation, on the fly, suddenly you want to point out a particular thing… wouldn’t it be nice to have a tool to help?

Turns out, there is one, a very simple tool to do this. I use it every month.

Gromit-mpx is simple. <F9> to start being able to draw, Shift-Ctrl-<F9> to clear everything you drew, and Ctrl-<F9> to stop being able to draw (but leave everything on the screen). Just make sure gromit-mpx is running in the background, and you are set for all your drawing and annotating needs. Even people like me, who just run dwm and not with any compositor, I can annotate my screen quickly.

But with just a few lines, I can clarify what I meant to share. I won’t be winning any art awards, but it works.

including most of the binary for those values

Do note that the annotations stick around, even after you scroll the window, or switch to a different screen entirely.

So keep gromit-mpx around, it might be useful someday.

For more information, there is always the gromit-mpx(1) manpage.
