Convert Bimap to Thumbnail

原标题：Convert Bitmap to Thumbnail

我想从C#的形象中产生一个umb。我如何这样做?

最佳回答

Image 。例常使用:

var filename = "fb.png";

using(var image = Image.FromFile(filename))
{
    using(var thumbnail = image.GetThumbnailImage(20/*width*/, 40/*height*/, null, IntPtr.Zero))
    {
        thumbnail.Save("thumb.png");
    }
}

这将产生20x40px thumbnail版本的脂肪。
