How to take screenshot from command line on BBB Angstrom

Question

Hi I have a BBB which is running on Angstrom 2013 image. For display purpose I am using a cape which is connected to gpio extensions. There is a Qt application running on BBB, which use to get displayed on the Cape. How can I take screenshot of the cape. I want to take some screen-shot of the running application. I couldn't find gnome-screenshot on angstrom image, using import command to take screenshot I got an error regarding x11.

How can I get the screenshot?

Answer 1

You can try and install scrot

On Ubuntu based Beagle Bone Black, I installed it as follows:

sudo apt-get install scrot

To Capture a screenshot:

scrot -q 100 /home/debian/Desktop/Desktop.jpg
#-q 100 == best quality
# /home/debian/Desktop/Desktop.jpg is path where to store captured screenshot
