//以下code是同學的
  int wp = wm - 1; //我不懂,不過如果以mask為3X3pading用wp=1,
  int hp = hm - 1;
 int *fp = new int [(w wp)*(h hp)]; //我的意思是這用(w 1)*(h 1) 
  //padding (f, w, h, fp, wm, hm);
  padding_ray (f, w, h, fp, w wp, h hp);

引言:

const int dx[] = { -1, 0, 1,
                   -1, 0, 1,
                   -1, 0, 1 };
const int dy[] = { -1,-1,-1,
                    0, 0, 0,
                    1, 1, 1 };請問為什要設定此?    template 
void filtering(TYPE_1 *image, int w, int h, const float
 *filter, TYPE_2 *img)
{
   for ( int r=1 ; r255 ) value = 255;
              img[r*w c] = value;
          }
     }
}    因為我的電腦不曉得是刪除什檔案看單獨看bmp檔有問題
所以我暫時沒有執行您的code,請問您文中說"Image1中放入一個bmp圖檔。"
是這樣的意思嗎?想請教一下,您這是拿彩色圖檔取RGB某一分量,換句話說,同時
也做了彩色變灰階嗎?

#include < JPEG.hpp > // 要記得include
void __fastcall toGray(TImage *image)
{ int w, h, r, g, b, gray, index;
  Byte *ptr;      w = image->Picture->Width;
  h = image->Picture->Height;
  image->Picture->Bitmap->PixelFormat = pf24bit;
  for (int row=0; rowPicture->Bitmap->ScanLine[row];
       index = 0;
       for (int col=0; colExecute() )
    { Image1->Picture->LoadFromFile(OpenDialog1->FileName);
      Image1->Top = 5;
      Image1->Left = 5;
      Graphics::TBitmap *bmp = new Graphics::TBitmap();
      bmp->Width  = Image1->Picture->Width;
      bmp->Height = Image1->Picture->Height;
      bmp->Canvas->Draw(0,0,Image1->Picture->Graphic);
      Image1->Picture->Bitmap->Assign(bmp);
      Image1->Refresh();
      delete bmp;
    }
}

#include < JPEG.hpp > // 要記得include
我剛一跑程式出現這樣error message在這行:
[C   Error] Unit1.cpp(5): E2209 Unable to open include file ' JPEG.hpp ' 請問是我那裡有需要修改?

 
            ptr[idx 2] = image[index  ];  // 取紅色分量
            ptr[idx 1] = 0;
            ptr[idx  ] = 0;
            idx  = 3;
