推荐答案

重新绘制它： http://msdn.microsoft.com/en-us/library/4f9s3at1（v = vs.110）的.aspx [ ^ ]

有几个重载允许您重新缩放图像，而对于分辨率，您只需要在创建要绘制的目标位图时使用 Bitmap.SetResolution [ ^ 方法。

然后使用 GRA phics.FromImage [ ^ ]并使用它代替第一个链接的示例中的Graphics对象并设置！

Re-draw it: http://msdn.microsoft.com/en-us/library/4f9s3at1(v=vs.110).aspx[^]
There are several overloads that allow you to re-scale the image, and for resolution you just need to set that when you create the target bitmap to draw on, or using the Bitmap.SetResolution[^] method.
Then just get the Graphics context using Graphics.FromImage[^] and use that instead of the Graphics object in the example with the first link and you're set!
