How can I do a screen capture in Windows PowerShell?

How can I capture the screen in Windows PowerShell? I need to be able to save the screen to disk.

You can also use .NET to take the screenshot programatically (which gives you finer control):

[Reflection.Assembly]::LoadWithPartialName("System.Drawing")
function screenshot([Drawing.Rectangle]$bounds, $path) {
   $bmp = New-Object Drawing.Bitmap $bounds.width, $bounds.height
   $graphics = [Drawing.Graphics]::FromImage($bmp)
   
   $graphics.CopyFromScreen($bounds.Location, [Drawing.Point]::Empty, $bounds.size)
   
   $bmp.Save($path)
   
   $graphics.Dispose()
   $bmp.Dispose()
}

$bounds = [Drawing.Rectangle]::FromLTRB(0, 0, 1000, 900)
screenshot $bounds "C:\screenshot.png" # change path to somewhere writable
