WriteableBitmap的转换在C＃位图 [英] Converting WriteableBitmap to Bitmap in C#

问题描述

有没有办法转换 WriteableBitmap的来位图在C＃中？

推荐答案

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.
