剛剛我在以前的文章發現這段~想問一下若我有兩張bmp圖~檔名是123和124~要進行比對~那我要如何融入這個程式ㄋ for ( y = 0; y < MainForm->Image1->Height; y ) //統計兩個Frame像素質 { ptr1 = (Byte *)Bmp->ScanLine[y]; ptr2 = (Byte *)Bmp2->ScanLine[y]; for ( x = 0; x < MainForm->Image1->Width; x ) { a_pic = (ptr1[x*3] ptr1[x*3 1] ptr1[x*3 2])/3; b_pic = (ptr2[x*3] ptr2[x*3 1] ptr2[x*3 2])/3; aval[x][y] =a_pic; bval[x][y] =b_pic; } }

639673 您好：    您貼上來的程式敘述並不完整，其中有些變數的宣告沒有貼上來，無法進行完整的測試，因此僅就問題作回覆，無法確保運作結果是否正確？    將兩個圖檔代入該段程式的寫法大致如下，請參考：

Graphics::TBitmap *Bmp1 = new Graphics::TBitmap();
Graphics::TBitmap *Bmp2 = new Graphics::TBitmap();    Bmp1->PixelFormat = pf24bit;
Bmp2->PixelFormat = pf24bit;    Bmp1->LoadFromFile("c:\\123.bmp");
Bmp2->LoadFromFile("c:\\124.bmp");    Byte *ptr1;
Byte *ptr2;    for (int y = 0; y < Bmp1->Height; y  ) {
    ptr1 = (Byte *)Bmp1->ScanLine[y];
    ptr2 = (Byte *)Bmp2->ScanLine[y];
    for (int x = 0; x < Bmp1->Width; x  ) {
        a_pic = (ptr1[x*3]   ptr1[x*3 1] ptr1[x*3 2])/3;
        b_pic = (ptr2[x*3]   ptr2[x*3 1] ptr2[x*3 2])/3;
        aval[x][y] =a_pic;
        bval[x][y] =b_pic;
    }
}    if (memcmp(aval, bval, sizeof(bval[x][y]) ) == 0)
    ShowMessage("同一張圖形");
else
    ShowMessage("不同圖形");    delete Bmp1;
Bmp1 = NULL;
delete Bmp2;
Bmp2 = NULL;
