典範程式：

並以Bitmap類型的GetPixel(x翻譯社y)及SetPixel(x,y,color)兩個函數，對影像的每個

                    ImgData[x, y, 0] = gray;
                    ImgData[x, y, 1] = gray;
                    ImgData[x翻譯社 y, 2] = gray;

        public static Bitmap CreateBitmap(int[翻譯社 ,] ImgData)
        {   
            int Width = ImgData.GetLength(0);
            int Height = ImgData.GetLength(1);
            Bitmap myBitmap = new Bitmap(Width, Height翻譯社 PixelFormat.Format24bppRgb);

               pictureBox2.Image = null;
        }

處理，則必需重複呼喚上述兩個函式上百萬次，這種體式格局對程式而言顯得太沒有用率翻譯

Basic Image Processing support in C#>

Bitmap myBitmap = new Bitmap(ImageFileName) 載入影象檔.

指標內容的方式，將影象像素資料逐一讀入預定的像素陣列中並進行後續的影象處理，以加速速度。

        private void button2_Click(object sender, EventArgs e)  ///灰階影象處理
        {
            int[翻譯社 ,] ImgData = GetImgData(myBitmap);
            GrayProcess(ImgData);
            Bitmap processedBitmap = CreateBitmap(ImgData);

                                           ImageLockMode.WriteOnly,
                                           PixelFormat.Format24bppRgb);
         
            //Padding bytes的長度
            int ByteOfSkip = byteArray.Stride - myBitmap.Width * 3;

                }
            }
        }

簡單的數位影像處置 ( C# 篇) >

語法以下:

讀入影象檔轉為像素資料陣列，並進行灰階（Ｇrey Scale) 處理.

            if (openFileDialog1.ShowDialog() == DialogResult.OK)   ////由對話框選取圖檔
            {
                myBitmap = new Bitmap(openFileDialog1.FileName);
                pictureBox1.Image = myBitmap;
            }

            myBitmap.UnlockBits(byteArray);
            return ImgData;
        }

                    int gray = (int) ((double) ImgData[x翻譯社 y, 0] * 0.299  + (double) ImgData[x翻譯社 y, 1] * 0.587 + (double) ImgData[x, y翻譯社 2] * 0.114);

參考資料:

［C#] 載入影像檔一文中提到，C# 說話可以使用

 C#的Bitmap類型另提供一LockBits（）函式可將影象的指定區域資料以Byte Array的型式存放在記憶體空間中,。並傳回BitmapData類型的物件，個中BitmapData.Scan0則寄存像素Byte Array中第一個Byte的指標。 程式可以讀取

 unsafe　　　//進行指標處理所須宣佈。專案－＞屬性－＞建置－＞容許Unsafe程式碼須拔取。　
            {
                byte* imgPtr = (byte*)(byteArray.Scan0);

像素的R, G翻譯社 B值做讀出和寫入的動作翻譯但若是對一張百萬像素的影像做影象
