Thanks, these are just the features that I missed in raspi2png, especially the incremental file naming.

@cyperghost said in [Solved] How to bind a shell command to a hotkey? (raspi2png):

I'm the (proud??) owner of such a device but I prefer the Pie

What I meant - since you have one - maybe you can find an equivalent program to raspi2png for the Droid and be able to test it (not create one from scratch). Something like fbgrab or fbdump maybe.

@nicky_s14 Try reinstalling the library sudo apt-get install --reinstall libpng12-dev

@nicky_s14 Check if you have a snapshot.png in the /home/pi folder. It's not the folder where raspi2png is located, is the folder where the command was executed.
