Having trouble converting commandline to Magick.net Functions

[asdnfuvna]

How can I convert this command line ImageMagick arguments to Magick.Net functions?

1.png 2.png -alpha off ( -clone 0,1 -compose difference -composite -negate ) ( -clone 0,2 +swap -compose divide -composite ) -delete 0,1 +swap -compose Copy_Opacity -composite final_image.png

Thanks!

What have you tried so far and where are you stuck?

I'm stuck on if I have to do each function for both images like Alpha option off for image 1 and 2.
I'm also confused on how I can do -clone 0,1

            using (MagickImageCollection images = new MagickImageCollection())
            {
                MagickImage ImageWhite = new MagickImage($@"C:\Users\{Environment.UserName}\AppData\Local\Temp\1.png");
                MagickImage ImageBlack = new MagickImage($@"C:\Users\{Environment.UserName}\AppData\Local\Temp\2.png");
                ImageWhite.Alpha(AlphaOption.Off);
                ImageBlack.Alpha(AlphaOption.Off);
            }

You don't need the MagickImageCollection it is possible to do this without that in Magick.NET. Below is a step by step translation of the options into code:

// 1.png
using (var first = new MagickImage("1.png"))
{
    // 2.png
    using (var second = new MagickImage("2.png"))
    {
        // -alpha off
        first.Alpha(AlphaOption.Off);
        second.Alpha(AlphaOption.Off);

        // -clone 0,1
        // This clones the first and second image but we only need to clone the first
        using (var difference = first.Clone())
        {
            // -compose difference -composite
            difference.Composite(second, CompositeOperator.Difference);

            // -negate
            difference.Negate();

            // -clone 0,2 +swap
            // Clones the first and third image (difference) but we only need the third one because the order is swapped.
            using (var divide = difference.Clone())
            {
                // -compose divide -composite
                divide.Composite(first, CompositeOperator.DivideDst);

                // -delete 0,1
                // This removes 1.png and 2.png but we don't need to do that

                // +swap
                // This makes divide the first image and difference the second.

                // -compose Copy_Opacity -composite
                divide.Composite(difference, CompositeOperator.CopyAlpha);

                // final_image.png
                divide.Write("final_image.png");
            }
        }
    }
}
