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.
Example Usage
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 Examples of ImageMagick Usage.
