1. 加载首个图像使用新位图（文件名）


2. 加载第二图像相同的方式。


3. 通过调用的Graphics.FromImage(bitmap1）


4. 呼叫的graphics.DrawImage(bitmap2 ...）把第二图像上的第一个李>
   
5. bitmap1.Save（... ）新的图像保存到一个文件中。

I need to be able to take multiple images and overlay a smaller one on top of a larger one and save the result as a single image. How would I go about accomplishing this in C#?

1. Load the first image using new Bitmap(filename)
2. Load the second image the same way.
3. Get a Graphics object by calling Graphics.FromImage(bitmap1)
4. Call graphics.DrawImage(bitmap2...) to put the second image on the first
5. Call bitmap1.Save(...) to save the new image to a file.
