我自己寫了兩個TImage to 陣列,跟陣列 to TImage的副程式,但是執行陣列 to TImage後卻發現 RGB跟我原來的不一樣,不知道我這樣寫哪裡有問題?    

typedef struct tagRGBValue {
        BYTE    rgbBlue;
        BYTE    rgbGreen;
        BYTE    rgbRed;
} RGBValue;    void TImage2ImageMatrix(TImage *srcImage,Byte ImageMatrix[240][320])
{
  Byte *ptr;
  srcImage->Height =240;
  srcImage->Width=320;
  srcImage->Picture->Bitmap->PixelFormat = pf24bit;
  for (int row = 0; row < srcImage->Height; row  )
  {
   ptr = (Byte *)srcImage->Picture->Bitmap->ScanLine[row];
   for(int col = 0; col Width; col  )
         ImageMatrix[row][col]=(TColor)RGB(ptr[col*3],ptr[col*3 1],ptr[col*3 2]);
  }
}
void ImageMatrix2TImage(TImage *DestImage,Byte ImageMatrix[240][320])
{
    //Show
    Graphics::TBitmap *Bmp = new Graphics::TBitmap();
    Byte *ptr;
    Bmp->Assign(DestImage->Picture->Bitmap);        Bmp->PixelFormat = pf24bit;
    Bmp->Height==240;
    Bmp->Width=320;
    
    for (int Row=0; Row Height ; Row  )
      {
      RGBValue  *Pixel = (RGBValue *) Bmp->ScanLine[Row];
      for (int Col=0; Col < Bmp->Width; Col  , Pixel  )
        {
         Pixel->rgbRed =   GetRValue(ImageMatrix[Row][Col]);
         Pixel->rgbGreen = GetGValue(ImageMatrix[Row][Col]);
         Pixel->rgbBlue =  GetBValue(ImageMatrix[Row][Col]);
        }
      }
    DestImage->Picture->Bitmap->Assign(Bmp);
    delete Bmp;
}

您好: 不曉得是不是筆誤 < class="code"> Bmp->Height==240 順心

恩...是筆誤,我的彩色影像show出來的時候是紅色的,所以是R,G,B的值有問題,但是我還是搞不懂為什麼這樣寫會有問題...@@

harisan3 您好：    問題出在資料型態，我將您的程式改寫如下，經測試後可以正確運作，您參考看看吧：

typedef struct tagRGBValue {
    BYTE    rgbBlue;
    BYTE    rgbGreen;
    BYTE    rgbRed;
} RGBValue;    DWORD ImageMatrix[240][320];    void TImage2ImageMatrix(TImage *srcImage, DWORD ImageMatrix[240][320])
{
    srcImage->Height = 240;
    srcImage->Width  = 320;
    srcImage->Picture->Bitmap->PixelFormat = pf24bit;
    for (int row = 0; row < srcImage->Height; row  ) {
        // 既然 ImageMatrix2TImage() 都使用 ScanLine 了，此處也改成相同處理方式
        RGBValue  *Pixel = (RGBValue *) srcImage->Picture->Bitmap->ScanLine[row];
        for(int col = 0; col < srcImage->Width; col  )
            ImageMatrix[row][col]=(TColor)RGB(Pixel[col].rgbRed, Pixel[col].rgbGreen, Pixel[col].rgbBlue);
    }
}    void ImageMatrix2TImage(TImage *DestImage, DWORD ImageMatrix[240][320])
{
    Graphics::TBitmap *Bmp = new Graphics::TBitmap();
    Bmp->Assign(DestImage->Picture->Bitmap);        Bmp->PixelFormat = pf24bit;
    Bmp->Height = 240;
    Bmp->Width  = 320;
    
    for (int Row = 0; Row < Bmp->Height; Row  ) {
        RGBValue  *Pixel = (RGBValue *) Bmp->ScanLine[Row];
        for (int Col = 0; Col < Bmp->Width; Col  ) {
            Pixel[Col].rgbRed   = GetRValue(ImageMatrix[Row][Col]);
            Pixel[Col].rgbGreen = GetGValue(ImageMatrix[Row][Col]);
            Pixel[Col].rgbBlue  = GetBValue(ImageMatrix[Row][Col]);
        }
    }
    DestImage->Picture->Bitmap->Assign(Bmp);
    delete Bmp;
}

RedSnow 兄您好,問題真的解決了,之前沒考慮到RGB 是8x8x8 所以宣告成Byte 感謝您的幫助喔. 下次我會注意彩色跟灰階影像使用陣列時,型態宣告的問題. sizeof(int) --> 4 bytes sizeof(DWORD) --> 4 byte sizeof(char) --> 1 bytes sizeof(BYTE) --> 1 bytes
