How can I do a screen capture in Windows PowerShell?

Question

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

Answer 1

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" 

Answer 2

For the sake of completion, this script allows you to take screenshots across multiple monitors.

Base code comes from Jeremy

[Reflection.Assembly]::LoadWithPartialName("System.Drawing") [void] [System.Reflection.Assembly]::LoadWithPartialName("System.Drawing")  [void] [System.Reflection.Assembly]::LoadWithPartialName("System.Windows.Forms")  function screenshot($path)  {     $width = 0;     $height = 0;     $workingAreaX = 0;     $workingAreaY = 0;      $screen = [System.Windows.Forms.Screen]::AllScreens;      foreach ($item in $screen)     {         if($workingAreaX -gt $item.WorkingArea.X)         {             $workingAreaX = $item.WorkingArea.X;         }          if($workingAreaY -gt $item.WorkingArea.Y)         {             $workingAreaY = $item.WorkingArea.Y;         }          $width = $width + $item.Bounds.Width;          if($item.Bounds.Height -gt $height)         {             $height = $item.Bounds.Height;         }     }      $bounds = [Drawing.Rectangle]::FromLTRB($workingAreaX, $workingAreaY, $width, $height);      $bmp = New-Object Drawing.Bitmap $width, $height;     $graphics = [Drawing.Graphics]::FromImage($bmp);      $graphics.CopyFromScreen($bounds.Location, [Drawing.Point]::Empty, $bounds.size);      $bmp.Save($path);      $graphics.Dispose();     $bmp.Dispose(); } 

Can be called with: screenshot "D:\screenshot.png"
