[从OP评论中删除]
这是我的代码:

i have created an image in c#
but i don''t know how to get it''s path
how can i get it?

[Moved from OP Comment]
this is my code:

Bitmap sourceImg = new Bitmap("d:\\images\\a.bmp");
          Bitmap destImg = new Bitmap(sourceImg.Width, sourceImg.Height);

          Rectangle dataRect =
          new Rectangle(0, 0, sourceImg.Width, sourceImg.Height);
          BitmapData sourceData = sourceImg.LockBits(dataRect, ImageLockMode.ReadOnly, PixelFormat.Format32bppArgb);
          BitmapData destData =
          destImg.LockBits(dataRect, ImageLockMode.WriteOnly,
          PixelFormat.Format32bppArgb);
          IntPtr sourcePtr = sourceData.Scan0;
          IntPtr destPtr = destData.Scan0;
          byte[] buffer = new byte[sourceData.Stride];
          for (int row = 0; row < sourceImg.Height; row++)
          {
                             System.Runtime.InteropServices.Marshal.Copy(    sourcePtr, buffer, 0, sourceData.Stride);

              for (int i = 0; i < buffer.Length; i += 4)
              {
                                      buffer[i + 0] /= 2;
                  buffer[i + 1] /= 2;
                  buffer[i + 2] /= 2;
              }
              System.Runtime.InteropServices.Marshal.Copy(
              buffer, 0, destPtr, destData.Stride);
              sourcePtr = new IntPtr(sourcePtr.ToInt64() + sourceData.Stride);
              destPtr = new IntPtr(destPtr.ToInt64() + destData.Stride);
          }
          sourceImg.UnlockBits(sourceData);
          destImg.UnlockBits(destData);

推荐答案

并不知道您已保存了destImg 位图

It does not apprear that you have saved your destImg bitmap

destImg.Save(@"d:\images\MyNewBitmap.bmp")
