New Post: Is it possible to create tiled GIF images with Magick.NET?

// Could be larger but this works if every pixel in the block has a different colorint blockSize = 16;

using (MagickImage image = new MagickImage("input.png"))
{
  using (MagickImageCollection gif = new MagickImageCollection())
  {
    MagickImage background = new MagickImage(MagickColor.Transparent, image.Width, image.Height);
    background.AnimationIterations = 1;
    background.GifDisposeMethod = GifDisposeMethod.None;
    background.AnimationDelay = 0;
    gif.Add(background);
    
    for (int x = 0; x < image.Width; x += blockSize)
    {
      for (int y = 0; y < image.Height; y += blockSize)
      {
        MagickImage subImage = image.Clone();
        int subImageWidth = Math.Min(image.Width - x, blockSize);
        int subImageHeight = Math.Min(image.Width - x, blockSize);

        subImage.Crop(new MagickGeometry(x, y, subImageWidth, subImageHeight));
        subImage.GifDisposeMethod = GifDisposeMethod.None;
        subImage.AnimationDelay = 0;

        gif.Add(subImage);
      }
    }
  
    gif.Write("output.gif");
  }
}
