How to add padding to an image using MagickImage in .NET core

I'm trying to write a function that adds padding to an image but I'm not sure on how to do that with ImageMagick.

    public bool AddPadding(string filePath)
    {
        // Read from file
        using (MagickImage image = new MagickImage(filePath))
        {
            int imageSize;
            int imageX = image.Width;
            int imageY = image.Height;

            if(imageX > imageY)
            {
                imageSize = imageX;
            }
            else
            {
                imageSize = imageY;
            }

            MagickGeometry size = new MagickGeometry(imageSize, imageSize);
            // Probably do more stuff here?




            // Save the result
            image.Write(filePath);
        }
    }

What do I need to add so that the image is centered and whitespace is added to both left and right?

You can use the Extent method of MagickImage for this. Below is an example of how you could do that.

public bool AddPadding(string filePath)
{
    // Read from file
    using (MagickImage image = new MagickImage(filePath))
    {
        int imageSize = Math.Max(image.Width, image.Height);

        // Add padding
        image.Extent(imageSize, imageSize, Gravity.Center, MagickColors.Purple);

        // Save the result
        image.Write(filePath);
    }
}

This adds a purple padding so you might want to change the color to a different one instead.
