在C#/ .NET中合并两个图像

using System;
using System.Drawing;
using System.IO;

public class ImageMerge
{
    public static void Main()
    {
        string image1Path = "path/to/image1.jpg";
        string image2Path = "path/to/image2.jpg";
        string outputPath = "path/to/output.jpg";

        Bitmap bitmap1 = new Bitmap(image1Path);
        Bitmap bitmap2 = new Bitmap(image2Path);

        int width = Math.Max(bitmap1.Width, bitmap2.Width);
        int height = bitmap1.Height + bitmap2.Height;

        Bitmap mergedBitmap = new Bitmap(width, height);

        using (Graphics graphics = Graphics.FromImage(mergedBitmap))
        {
            graphics.DrawImage(bitmap1, new Point(0, 0));
            graphics.DrawImage(bitmap2, new Point(0, bitmap1.Height));
        }

        mergedBitmap.Save(outputPath);
    }
