如何使用C#将多个JPG图像合并到一个大(巨大)图像中

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

public static void MergeImages(string[] imagePaths, string outputImagePath)
{
    // 获取第一张图像的尺寸
    Image firstImage = Image.FromFile(imagePaths[0]);
    int width = firstImage.Width;
    int height = firstImage.Height;
    firstImage.Dispose();

    // 创建一个新的大图像对象
    Bitmap mergedImage = new Bitmap(width * imagePaths.Length, height);

    // 在大图像上绘制每个图像
    using (Graphics graphics = Graphics.FromImage(mergedImage))
    {
        int currentWidth = 0;
        foreach (string imagePath in imagePaths)
        {
            Image image = Image.FromFile(imagePath);
            graphics.DrawImage(image, currentWidth, 0);
            image.Dispose();
            currentWidth += width;
        }
    }

    // 保存合并后的图像
    mergedImage.Save(outputImagePath, ImageFormat.Jpeg);
    mergedImage.Dispose();
}

string[] imagePaths = { "image1.jpg", "image2.jpg", "image3.jpg" };
string outputImagePath = "mergedImage.jpg";
MergeImages(imagePaths, outputImagePath);
