有没有办法转换 WriteableBitmap的来位图在C#中?
这是pretty的直白,其实。下面是一些code,它的应该的工作。我没有测试过,我从我的头顶写它。
It's pretty straightforward, actually. Here's some code that should work. I haven't tested it and I'm writing it from the top of my head.
private System.Drawing.Bitmap BitmapFromWriteableBitmap(WriteableBitmap writeBmp)
{
System.Drawing.Bitmap bmp;
using (MemoryStream outStream = new MemoryStream())
{
BitmapEncoder enc = new BmpBitmapEncoder();
enc.Frames.Add(BitmapFrame.Create((BitmapSource)writeBmp));
enc.Save(outStream);
bmp = new System.Drawing.Bitmap(outStream);
}
return bmp;
}
在WriteableBitmap的继承一个的BitmapSource,可直接保存到流。然后,你建立从此流的位图。
The WriteableBitmap inherits from a BitmapSource, which can be saved directly to a stream. Then, you build a Bitmap from this stream.
