From gnome-screenshot command line, how do you predefine the area?
It looks like there isn't such an option but you can control your mouse from command line using xdotool
, so you can try to play with it:
(gnome-screenshot -a &); sleep 0.1 && xdotool mousemove 100 100 mousedown 1 mousemove 500 500 mouseup 1
I use (cmd &)
syntax to have command running in background (using just && here won't work because gnome-screenshot
waits for input) and make small delay (try to experiment with values of sleep) to be sure that mouse won't be moving before it's ready. Then I use mousemove x y
, mousedown 1
and mouseup 1
commands to simulate grabbing an area.
You should also check out more suited tool for getting screenshots which is import
from ImageMagick:
import -window root ~/Pictures/img.png -crop 100x100+1100+1100

So gnome-screenshot has the following options:
tim@Hairy14:~$ gnome-screenshot --help Usage: gnome-screenshot [OPTION…] Take a picture of the screen Help Options: -h, --help Show help options --help-all Show all help options --help-gtk Show GTK+ Options Application Options: -c, --clipboard Send the grab directly to the clipboard -w, --window Grab a window instead of the entire screen -a, --area Grab an area of the screen instead of the entire screen -b, --include-border Include the window border with the screenshot -B, --remove-border Remove the window border from the screenshot -p, --include-pointer Include the pointer with the screenshot -d, --delay=seconds Take screenshot after specified delay [in seconds] -e, --border-effect=effect Effect to add to the border (shadow, border, vintage or none) -i, --interactive Interactively set options -f, --file=filename Save screenshot directly to this file --version Print version information and exit --display=DISPLAY X display to use
The one I'm interested in is
-a
.If it run it, the following happens, I can click and drag anywhere on the screen and it saves an image, of the are I chose.
I have the short cut Alt+Shift+4 set up for this.
But what I want is a predefined area, somehting allong the lines of this:
gnome-screenshot -a 400x500+100x100
(i.e. 400 down, 500 in and 100x100 area).
Is this possible, and is there a command to do this?
NB: I could use the image cropping tool
convert -crop
like this:convert -crop 100x100+50+50 Pictures/Screenshot.png Pictures/Screenshot-cropped.png
but I would like it if it was built in, as cropping a full print screen makes it blurry...
