Answer 1

在窗体添加 按钮，TImage 控件 Image1

__fastcall TForm1::TForm1(TComponent* Owner)
: TForm(Owner)
{
Image1->AutoSize = true;
Image1->Picture->LoadFromFile("c:\\1.bmp");
}

void __fastcall TForm1::Button1Click(TObject *Sender)
{
int x, y;
int w = Image1->Width;
int h = Image1->Height;

for (y = 0; y < h; y++)
for (x = 0; x < w; x++)
{
返回点的RGB值 = Image1->Canvas->Pixels[x][y];
}
}
