谁能帮我看看这个控件(源代码)为什么不能显示?把c++builder程序转换成Delphi的。 (100分)

上面的代码是不是太多了，那就简单点，哪位大哥能帮我下面的C++builder 程序
改成Delphi程序，小弟先谢谢了。
...

Canvas->FillRect(Rect(0, 0, Width, Height));
}
...
void __fastcall TSiren:aint(void)
{
std::auto_ptr<Graphics::TBitmap> TheImage(new Graphics::TBitmap());
std::auto_ptr<TBltBitmap> OverlayImage(new TBltBitmap());

TheImage->Height = Height;
TheImage->Width = Width;

只是有点麻烦巴，应该不会有什么技术障碍

Graphics::TBitmap* AnImage
这行代码对应的delphi代码是什么？
可以定义指向TBitmap的指针吗？可以的话，如何定义？

AnImage : ^Graphics.TBitmap

谢谢expect兄的回答,小弟的C++水平实在太差。
可是 void __fastcall TPipeLine:aintBackground(Graphics::TBitmap* AnImage)
变成procedure TPipeLine.PaintBackground(AnImage : ^Graphics.TBitmap ) ;通不过。
麻烦你帮我把这几句代码变成delphi的。先谢谢了。
void __fastcall TSiren:aint(void)
{
std::auto_ptr<Graphics::TBitmap> TheImage(new Graphics::TBitmap());
..
PaintBackground(TheImage.get());
...
}
void __fastcall TPipeLine:aintBackground(Graphics::TBitmap* AnImage)
{
...}

我发到你的邮箱了！

DELPHI中一般不需要显形的使用对象指针。我晚上看看帮你改一下。

谢谢大家了，尤其是爱峥提供的源代码。

Object Passcal 不支持 模板，不能直接翻译
