參考資料:

    {
        public Form1()
        {
            InitializeComponent();

讀入影像檔轉為像素資料陣列,並進行灰階(Grey Scale) 處置.

程式碼如下:
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Drawing.Imaging;
using System.Linq;
using System.Text;
using System.Windows.Forms;

            BitmapData byteArray = myBitmap.LockBits(new Rectangle(0, 0, Width, Height),
                                           ImageLockMode.WriteOnly,
                                           PixelFormat.Format24bppRgb);
         
            //Padding bytes的長度
            int ByteOfSkip = byteArray.Stride - myBitmap.Width * 3;

BitmapData byteArray = myBitmap.LockBits( new Rectangle( 0 翻譯社 0 翻譯社 myBitmap.Width 翻譯社 myBitmap.Height ) 翻譯社 ImageLockMode.ReadWrite  翻譯社 PixelFormat.Format24bppRgb  );

處置懲罰,則必需反複呼喚上述兩個函式上百萬次,這類方式對程式而言顯得太沒有用率翻譯

Basic Image Processing support in C#>

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

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

指標內容的體例,將影象像素資料一一讀入預定的像素陣列中並進行後續的影象處置,以加速速度。

範例程式:

        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);
            pictureBox2.Image = processedBitmap;

 

語法以下:

        }
        private int[, ,] GetImgData(Bitmap myBitmap)
        {
            int[翻譯社,] ImgData = new int[myBitmap.Width, myBitmap.Height, 3];
            BitmapData byteArray = myBitmap.LockBits(new Rectangle(0, 0, myBitmap.Width, myBitmap.Height), ImageLockMode.ReadWrite, PixelFormat.Format24bppRgb);
            int ByteOfSkip = byteArray.Stride - byteArray.Width * 3;
            unsafe  //專案->屬性->建置->容許Unsafe程式碼須拔取。           

            unsafe       
            {                                   // 指標取出影像資料
                byte* imgPtr = (byte*) byteArray.Scan0;
                for (int y = 0; y < Height; y++)
                {
                    for (int x = 0; x < Width; x++)
                    {
                        *imgPtr = (byte)ImgData[x, y, 2];       //B
                      
                        *(imgPtr+1) = (byte)ImgData[x, y, 1];   //G
                      
                        *(imgPtr+2) = (byte)ImgData[x, y, 0];   //R 
                        imgPtr += 3;
                    }
                    imgPtr += ByteOfSkip; // 跳過Padding bytes
                }
            }
            myBitmap.UnlockBits(byteArray);
            return myBitmap;
        }


 C#的Bitmap類型另供應一LockBits()函式可將影象的指定區域資料以Byte Array的型式寄存在記憶體空間中翻譯社。並傳回BitmapData類型的物件,此中BitmapData.Scan0則寄存像素Byte Array中第一個Byte的指標。 程式可以讀取

                }
            }
        }

 unsafe   //進行指標處置懲罰所須宣佈。專案->屬性->建置->允許Unsafe程式碼須拔取。 
            {
                byte* imgPtr = (byte*)(byteArray.Scan0);
                for (int y = 0; y < byteArray.Height; y++)
                {
                    for (int x = 0; x < byteArray.Width; x++)
                    {
                        ImgData[x
翻譯社 y翻譯社 2] = (int) *(imgPtr);
                        ImgData[x翻譯社 y, 1] = (int) *(imgPtr + 1);
                        ImgData[x翻譯社 y, 0] = (int) *(imgPtr + 2);
                        imgPtr += 3;
                    }
                    imgPtr += ByteOfSkip;
                }
            }
