How to use Animated GIF with TImage component?

In Delphi, the Timage component can play an animated GIF image:

(Image1.Picture.Graphic as TGIFImage).Animate := True;

I convert this code to C++ equivalent:

((TGIFImage)Image1->Picture->Graphic)->Animate = true;

But I get an error:

[bcc32c Error] Unit1.cpp(60): no matching conversion for C-style cast from 'Vcl::Graphics::TGraphic *' to 'Vcl::Imaging::Gifimg::TGIFImage'
  Vcl.Imaging.GIFImg.hpp(937): candidate constructor not viable: requires 0 arguments, but 1 was provided

What's the problem?

You are missing a * in your type-cast:

((TGIFImage*)Image1->Picture->Graphic)->Animate = true;
           ^

And then, consider using a C++-style cast instead of a C-style cast:

static_cast<TGIFImage*>(Image1->Picture->Graphic)->Animate = true;
