In the previous part, we saw how to make screenshots in the terminal by using the
xwd command. In this part, we’ll meet the
import command is part of
imagemagick package. To install it, under Debian and Debian-based operating systems 🔗 you can run:
🚀 ~ sudo apt install imagemagick
import also relies on the X Window System.
🚀 ~ import window.png
The command above will provide us a pointer to select the window we want to take a screenshot of. Unlike
xwd, where the foreground windows were being captured as well, the
import command will capture only the window we select, and even if there is another window in the foreground, it will be omitted. This is a big plus over
xwd, if you think about it. 🙃
To include the window frame in the screenshot we use the
frame flag again, like this:
🚀 ~ import -frame window.png
To make a screenshot of the entire screen we can use the
window flag. Note: when using the
window flag, we should provide a window id as well. In the example below, window id equals to
root since we want to capture the whole screen.
🚀 ~ import -window root entire_screen.png
The same result can be achieved by using the
screen flag, this time with pointer need to be clicked somewhere on the screen (but NOT on the general OS menus at the top or bottom, etc):
🚀 ~ import -screen entire_screen.png
Another big plus over
xwd is that
import supports window background transparency when capturing an entire screen.
import is part of ImageMagick, it supports numerous formats for the output file. Here are some of them:
- image/webp (requires webp to be installed in your system, see deb 🔗 , see google devs 🔗.)
The full list of image formats ImageMagick supports can be found here:
🍰 The cherry on the cake: selecting a custom area to grab
It’s very common for a GUI client to have a way to select a custom area to grab when taking a screenshot. But for a CLI command, this is a really cool feature.
🚀 ~ import custom_area_screenshot.png
The window pointer here is able to select a custom area of the screen as well. 😉
