原文:
将byte[]转为WriteableBitmap对象
//convert the bytes to WriteableBitmap
privateWriteableBitmap BytesToImage(byte[] src, int lw, int lh)
{
WriteableBitmap wbbitmap = newWriteableBitmap(lw, lh);
Stream s = wbbitmap.PixelBuffer.AsStream();
s.Seek(0, SeekOrigin.Begin);
s.Write(src, 0, lw * lh * 3);
return wbbitmap;
}
注：这里默认的WriteableBitmap对象为24位位图对象，如果是32位，则由流写入byte[]的时候要写为lw*lh*4。
