在 PowerShell 5.1 中你可以使用 Get-clipboard

In PowerShell 5.1 you can use Get-clipboard

 get-clipboard -format image
 $img = get-clipboard -format image
 $img.save("c:\temp\temp.jpg")

这也应该有效:

Add-Type -AssemblyName System.Windows.Forms
$clipboard = [System.Windows.Forms.Clipboard]::GetDataObject()
if ($clipboard.ContainsImage()) {
    $filename='c:\temp\test3.png'         
    [System.Drawing.Bitmap]$clipboard.getimage().Save($filename, [System.Drawing.Imaging.ImageFormat]::Png)
    Write-Output "clipboard content saved as $filename"
} else {
    Write-Output "clipboard does not contains image data"
}
