Convert image format and image size using Powershell script

This is an example of powershell script function that changes image format and size.
I've just updated the code from internet and using this on my powershell project.
$image is the file path of image file.


[System.Reflection.Assembly]::LoadWithPartialName("System.Drawing")
function Convert-Image{
    param($image,$toFormat,$saveTo,$smalldim,$bigdim)
 
    $baseName = [System.IO.Path]::GetFileNameWithoutExtension($image)
    $img = [System.Drawing.Image]::FromFile($image)
 
    "$image"
    if ($img.Width -gt $img.Height) {
        $width = $bigdim
        $height = $smalldim
    } else {
        $width = $smalldim
        $height = $bigdim
    }
 
    $ResizedImage = New-Object System.Drawing.Bitmap @($width, $height)
    $graphics = [System.Drawing.Graphics]::FromImage($ResizedImage)
    $graphics.DrawImage($img, 0, 0, $Width, $Height)
    $graphics.Dispose()
    $ResizedImage.save("$saveTo\$baseName.$toFormat",$toFormat)
}
