grim + slurp > "screenshot region is empty" #59

Open Macellatore opened 5 years ago

Macellatore commented 5 years ago

Hello, i'm using the latest grim installed from pacman (grim-1.2.0-2). If calling grim (either with slurp getting the coords or when setting them manually) with the -g option, this is the output:

macellatore# grim -g "10,20 300x400" screenshot.png                                                                                                                                           
screenshot region is empty

It broke all of a sudden, last month it was working fine.

Can you run swaymsg -t get_outputs?

This is because your only output is positioned at 0,1080. 10,20 300x400 is outside of those coordinates. We should probably print a better error message.

Regarding slurp giving wrong coordinates, maybe this is an instance of https://github.com/emersion/slurp/issues/37?

Sure, it has to be it! Changing my sway .config file from:

output eDP-1 position 0,1080
output HDMI-A-1 position 0,0

to:

output eDP-1 position 0,0
output HDMI-A-1 position 0,-1080

allowed me to get the right coords (at least for the primary display) without changing the relative position of my displays. Thanks a lot!
