How to Take a Screenshot Using PowerShell

The first step is to take a screenshot and set its dimensions. Run the following commands to take a screenshot with the given dimensions:

[void][reflection.assembly]::loadwithpartialname("system.windows.forms")
$DemoScreenshot = [System.Windows.Forms.SystemInformation]::VirtualScreen
$WIDTH = $DemoScreenshot.Width
$HEIGHT = $DemoScreenshot.Height
$LEFTDIM = $DemoScreenshot.Left
$TOPDIM = $DemoScreenshot.Top

The above code will take the screenshot using reflection.assembly and system.windows.forms with the given dimensions width, height, left, and right.

The next step is to create an image of the taken screenshot; we will save the screenshot as a BMP file. Run the following commands to create an image of the screenshot:

$BitmapScreenshot = New-Object System.Drawing.Bitmap $WIDTH, $HEIGHT
$FinalScreenshot = [System.Drawing.Graphics]::FromImage($BitmapScreenshot)
$FinalScreenshot.CopyFromScreen($LEFTDIM, $TOPDIM, 0, 0, $BitmapScreenshot.Size)

The code above creates a new object as a bitmap image and then assigns the above-taken screenshot. Once the image is created, the next step is to save it in the given path.

The next thing to do is to save the screenshot to the given path. Run the following commands:

$FinalFile = 'c:\Users\Sheeraz\demo.bmp'
$BitmapScreenshot.Save($FinalFile)
