在C#中将WriteableBitmap转换为位图

Question

有没有办法在C#中将WriteableBitmap转换为Bitmap？

Answer 1

实际上,这很简单.这里有一些应该有用的代码.我没有测试过它,而且我是从头顶写的.

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;
}

WriteableBitmap继承自BitmapSource,可以直接保存到流中.然后,您从此流构建一个位图.
