Taking screenshots on the Raspberry PIPosted Oct 26 2014 by Florian Wesch
Want to share something you created on your PI and could figure out the best way to create a screenshot? This small blog post will show you an easy way to create snapshots. Screenshots work both in X and in the linux console since the tool directly captures the screen using the lowlevel Dispmanx API.
Installing the tool
Installing should be easy. First fetch the source code using git:
pi@raspberrypi ~ $ git clone https://github.com/info-beamer/tools.git Cloning into 'tools'... remote: Counting objects: 36, done. remote: Total 36 (delta 0), reused 0 (delta 0) Unpacking objects: 100% (36/36), done. pi@raspberrypi ~ $
Now you have the code available in the directory tools. Enter the directory tools/screenshot and run make.
pi@raspberrypi ~ $ cd tools/screenshot/ pi@raspberrypi ~/tools/screenshot $ make cc -DHAVE_LIBBCM_HOST -DUSE_EXTERNAL_LIBBCM_HOST [...] screenshot.c -o screenshot pi@raspberrypi ~ $
You can now use the program screenshot. For easier use you can also install it in /usr/local/bin so you can run it from anywhere:
pi@raspberrypi ~/tools/screenshot $ sudo make install install -D -o root -g root -m 755 screenshot /usr/local/bin/screenshot pi@raspberrypi ~/tools/screenshot $
Taking screenshots is easy. Just call the screenshot program and send its output to a file:
pi@raspberrypi ~ $ screenshot > /tmp/my-first-screenshot.jpg pi@raspberrypi ~ $
Now you have the current content of the screen captured in /tmp/my-first-screenshot.jpg.
