需要帮助将此short []转换为灰度bmp
当前错误：http : //grabilla.com/04c0f-dcadafc9-1274-4cbf-a3a9-dc47d5148c25.html# tdata数组是short []或list <int16> its短灰度高度图

public partial class Form1 : Form

    public Form1()

        h = 1536;
        w = 1536;

经过几个小时的搜索，终于找到了正确的搜索词：）

好的，因此以上链接使我考虑了以下内容。

最终的解决方案是这样

using System.Windows;
using System.Windows.Media;
using System.Windows.Media.Imaging;
using System.IO;
namespace WpfApplication1
{
  public partial class Window1 : Window
  {
    public Window1()
    {
      InitializeComponent();
    }
    private void button1_Click(object sender, RoutedEventArgs e)
    {
      short[] Buf = new short[64 * 64];
      BitmapSource bmpSrc = BitmapSource.Create(
        64, 64, 96, 96, PixelFormats.Gray16, null, Buf, 128);
      TransformedBitmap transformedBmp = new TransformedBitmap(bmpSrc, new RotateTransform(-90));
      PngBitmapEncoder enc = new PngBitmapEncoder();
      enc.Frames.Add(BitmapFrame.Create(transformedBmp));
      using (FileStream fs = new FileStream("D:\\Temp\\Test.png", FileMode.Create))
      {
        enc.Save(fs);
      }
    }
   }
   }
