CurrentScreenImage[{{xmin,ymin},{xmax,ymax}}]

returns the specified rectangle from the image of all current display screens.

Details and Options

  • The primary display monitor is typically numbered 1, and the image from it can be captured with CurrentScreenImage[1].
  • The list of all display screens is given by SystemInformation["Devices","ScreenInformation"].
  • CurrentScreenImage returns an image that contains a faithful representation of pixels on your display screen.
  • In the form CurrentScreenImage[{{xmin,ymin},{xmax,ymax}}], the coordinates are measured from the bottom left of the complete area of all current display screens.
  • CurrentScreenImage always shows a rectangular display area. Any pixels that lie outside the display areas for any screen are assigned a color specified by the setting for the option Background.
