我有一个形象，是240×320（纵向iPhone摄像头的图像），我需要以编程方式（在C＃）加入白酒吧向两侧增加了完整的图像大小为320x320起。我不想缩放图像，因为这会搞乱宽高比。

我已经找到了很多有关如何删除白条用C＃，但没有有关如何添加这些信息。我很茫然。没有人有任何的输入，可能导致我的正确方向？

多谢你， 布雷特

 使用（System.Drawing.Image对象SRC = System.Drawing.Image.FromFile（picture.jpg））
{
       使用（BMP位图=新位图（320，320））
       {
                图形G = Graphics.FromImage（BMP）;
                g.Clear（Color.White）;
                g.DrawImageUnscaled（源，60，0，240，320）;
                bmp.Save（file.jpg，ImageFormat.Jpeg）;
       }
}
 

记住使用后处置的对象;）

I have an image that is 240x320 (iphone camera image in portrait), and I need to programmatically (in C#) add white "bars" to the sides increasing the full image size to 320x320. I don't want to scale the image because that would mess up the aspect ratio.

I have found a lot of info about how to remove white bars with c#, but nothing about how to add them. I am at a loss. Does anyone have any input that might lead me the correct direction?

Thanks a bunch, Brett

using (System.Drawing.Image src = System.Drawing.Image.FromFile("picture.jpg"))
{
       using (Bitmap bmp = new Bitmap(320, 320))
       {
                Graphics g = Graphics.FromImage(bmp);
                g.Clear(Color.White);
                g.DrawImageUnscaled(src, 60, 0, 240, 320);
                bmp.Save("file.jpg", ImageFormat.Jpeg);
       }
}

Remember to dispose the object after use ;)
