[Fwd: [Insight-developers] TImage::ImageDimension]

[Yinpeng Jin]

Yes, this works for me. thanks.
BTW, how to access the Input Image size in the below case?

template<class Tinput, class Toutput>
class A:public FilterImageToImage<Tinput,Touput>
{

void fun(){
   Tinput::SizeType size;
   size=this->GetInput()->GetSize();
  }

}

is this gona to work?
