我正在尝试从JPG中提取BitmapImage。这是我的代码:
FileStream fIn = new FileStream(sourceFileName, FileMode.Open); // source JPG
Bitmap dImg = new Bitmap(fIn);
MemoryStream ms = new MemoryStream();
dImg.Save(ms, ImageFormat.Jpeg);
image = new BitmapImage();
image.BeginInit();
image.StreamSource = new MemoryStream(ms.ToArray());
image.EndInit();
ms.Close();
图像以0×0图像返回,这当然意味着它不起作用。我该怎么做?
答案 0 :(得分:22)
试试这个:
public void Load(string fileName)
{
using(Stream BitmapStream = System.IO.File.Open(fileName,System.IO.FileMode.Open ))
{
Image img = Image.FromStream(BitmapStream);
mBitmap=new Bitmap(img);
//...do whatever
}
}
或者你可以这样做(source):
Bitmap myBmp = Bitmap.FromFile("path here");
