Example Usage • Option Summary
Use the import
program to capture some or all of an X server screen and save the image to a file. See Command Line Processing for advice on how to structure your import
command or see below for example usages of the command.
We list a few examples of the import
command here to illustrate its usefulness and ease of use. To get started, lets import an image in the JPEG format:
import rose.jpg
To capture the entire X server screen in the Postscript image format:
import -window root screen.ps
You can find additional examples of using import
in Graphics from the Command Line. Further discussion is available in More Graphics from the Command Line and .

command recognizes these options. Click on an option to get more details about how that option works.
