| Linux / Unix Command: import |
NAME
import - capture some or all of an X server screen and save the image to a file.SYNOPSIS
DESCRIPTION
Import reads an image from any visible window on an X server and outputs 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 rectangle, just release the button. The keyboard bell is rung once at the beginning of the screen capture and twice when it completes.
EXAMPLES
To select an X window or an area of the screen with the mouse and save it in the MIFF image format to a file entitled window.miff, use:
import window.miff
To select an X window or an area of the screen with the mouse and save it in the Encapsulated Postscript format to include in another document, use:
import figure.eps
To capture the entire X server screen in the JPEG image format in a file entitled root.jpeg, without using the mouse, use:
import -window root root.jpeg
To capture the 512x256 area at the upper right corner of the X server screen in the PNG image format in a well-compressed file entitled corner.png, without using the mouse, use:
import -window root -crop 512x256-0+0 -quality 90
corner.png
OPTIONS
Options are processed in command line order. Any option you specify on the command line remains in effect until it is explicitly changed by specifying the option again with a different effect.
Import options can appear on the command line or in your X resources file. See X(1). Options on the command line supersede values specified in your X resources file.
For a more detailed description of each option, see ImageMagick(1).
