Question

我有一个像素数组，我想打开它作为位图。

我使用的方法如下：http://www.tek-tips.com/viewthread.cfm?qid=1264492：

/// <summary>
/// function CopyDataToBitmap
/// Purpose: Given the pixel data return a bitmap of size [352,288],PixelFormat=24RGB 
/// </summary>
/// <param name="data">Byte array with pixel data</param>
public Bitmap CopyDataToBitmap(byte[] data)
{
  //Here create the Bitmap to the know height, width and format
  Bitmap bmp = new Bitmap( 352, 288, PixelFormat.Format24bppRgb);  

  //Create a BitmapData and Lock all pixels to be written 
  BitmapData bmpData = bmp.LockBits(
                       new Rectangle(0, 0, bmp.Width, bmp.Height),   
                       ImageLockMode.WriteOnly, bmp.PixelFormat);

  //Copy the data from the byte array into BitmapData.Scan0
  Marshal.Copy(data, 0, bmpData.Scan0, data.Length);


  //Unlock the pixels
  bmp.UnlockBits(bmpData);


  //Return the bitmap 
  return bmp;
}

除了图像是黑/白之外，我对阵列不太了解。问题可能在于：PixelFormat.Format24bppRgb。如何在不尝试所有格式的情况下告诉格式？

Array看起来像这样：

"0,0,0,0,0,0,0,0,0,0,0,0,0,255,0,0,0,0,0,0,0,0,0,0,0,0,0,255,255,255,255,0,0,0,0,0,0,0,0,0,0,255,255,255,255,255,0,0,0,0,0,0,0,0,0,0,255,255,255,0,0,0,0,0,0,0,0,0,0,0,255,255,255,255,0,0,0,0,0,0,0,0,0,255,255,255,255,255,255,0,0,0,0,0,0,0,0,0,255,255,255,255,0,0,0,0,0,0,0,0,0,0,0,0,255,255,0,0,0,0,0,0,0,0,0,0,0,0,0,0,255,255,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,255,255,0,0,0,0,0,0,0,0,0,0,255,255,255,0,255,255,0,0,0,0,0,0,0,255,255,255,255,255,255,0,255,255,255,0,0,0,0,255,255,255,255,255,0,0,0,0,0,255,255,0,255,255,255,255,255,255,0,0,0,0,0,0,0,255,255,255,255,255,255,0,0,0,0,0,0,0,0,0,0,0,255,255,0,0,0,0,0,0,0,0,0,0,0,0,0,0,255,255,0,0,0,0,0,0,0,0,0,0,0,0,0,0,255,255,255,0,0,0,0,0,0,0,0,0,0,0,0,0,0,255,255,0,0,0,0,0,0,0,0,0,0,0,0,0,0,255,255,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,255,255,0,0,0,0,0,0,0,0,0,0,0,0,0,0,255,255,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0"

我将图像保存到磁盘上：

var img = CopyDataToBitmap(result.Pixels);
img.Save("img.jpg", ImageFormat.Jpeg);

将像素数组读取到位图会返回黑色图像
