Screen Capture

# To select an area of the screen with the mouse
import figure.eps

# an X window with frame
import -frame app-snap.jpg

# To capture the entire X server screen
import -window root root.jpeg

Import reads an image from any visible window on an X server and out- puts it as an image file. You can capture a single window, the entire screen, or any rectangular portion of the screen. Use display for redisplay, printing, editing, formatting, archiving, image processing, etc. of the captured image.

The target window can be specified by id, name, or may be selected by clicking the mouse in the desired window. If you press a button and then drag, a rectangle will form which expands and contracts as the mouse moves. To save the portion of the screen defined by the rectan- gle, just release the button. The keyboard bell is rung once at the beginning of the screen capture and twice when it completes.
