Example: Merging Images 

var images = new List<Image>();
string[] files = new string[] { "template.png", "template.jpg" };
foreach (var fileName in files)
{
    images.Add(Image.Load(fileName));
}

MergeImages(images, 0); // Horizontal merge
MergeImages(images, 1); // Vertical merge

void MergeImages(List<Image> images, byte direction)
{
    int width = direction == 0 ? images.Sum(img => img.Width) : images.Max(img => img.Width);
    int height = direction == 1 ? images.Sum(img => img.Height) : images.Max(img => img.Height);

    using (var merged = Image.Create(new PngOptions() { ColorType = PngColorType.TruecolorWithAlpha }, width, height))
    {
        var graphics = new Graphics(merged);
        float x = 0, y = 0;
        foreach (var img in images)
        {
            graphics.DrawImage(img, new RectangleF(x, y, img.Width, img.Height));
            if (direction == 0) x += img.Width; else y += img.Height;
        }
        merged.Save("result_" + direction + ".png");
    }
}
