Is there a way to use the patterns built in to ImageMagick

[cstrachan88]

In the past, I have used the command line to overlay patterns on images using the -size command:

• magick -size 64x64 pattern:RIGHT45 output.png
• magick img.png ( -size 64x64 pattern:RIGHT45 -transparent white ) -flatten output.png

You can find documentation for this here. Is there a way to access this through Magick.NET? Poking around, I don't see a way to do that currently in the documentation or through code.

See also issue #3 from a few years back.

You can use the pattern as the filename in the constructor of a MagickImage:

using (var image = new MagickImage("pattern:RIGHT45", 64, 64))
{
    image.Write("output.png");
}

And for the second command you will need to use a MagickImageCollection:

using (var images = new MagickImageCollection())
{
    images.Add(new MagickImage("img.png"));

    var right = new MagickImage("pattern:RIGHT45", 64, 64);
    right.Transparent(MagickColors.White);
    images.Add(right);

    using (var output = images.Flatten())
    {
        output.Write("output.png");
    }
}
