[Insight-users] Paste Image Filter

[alexandre govignon]

Hi Luis i try to use the PasteImageFilter...
But there is no effect on the image...
In the following lines i have written my function.
Please help me...

void CDose::Padder2D(string Path1)
{

	ImageType2D::Pointer InImage=ImageType2D::New();
	ReaderType2D::Pointer reader=ReaderType2D::New();
	WriterType2D::Pointer writer=WriterType2D::New();
	reader->SetFileName(Path1);
	try
	{
		reader->Update();
		InImage=reader->GetOutput();
	}
	catch (itk::ExceptionObject & e)
	{
		std::cerr << "exception in file reader " << std::endl;
		std::cerr << e << std::endl;
	}
	ImageType2D::RegionType Region = (InImage->GetRequestedRegion());
	ImageType2D::SizeType size;
	ImageType2D::IndexType index;
	index[ 0] = Region.GetIndex()[0 ];
	index[ 1] = Region.GetIndex()[1 ];
	size[ 0] = Region.GetSize()[0 ];
	size[ 1] = Region.GetSize()[1 ];
	int DimX=size[0];
	int DimY=size[1];
	int DX=0;
	int DY=0;
	cout << DimX << "   " << DimY << endl;
	for(int i=1;i<18;i++)
	{
		if(DimX>=pow(2.0,i) && DimX<pow(2.0,i+1))
		{
			DX=pow(2.0,i+1);
		}
	}
	DimY=reader->GetOutput()->GetBufferedRegion().GetSize()[1];
	for(int i=1;i<18;i++)
	{
		if(DimY>=pow(2.0,i) && DimY<pow(2.0,i+1))
		{
			DY=pow(2.0,i+1);
		}
	}
	cout << DX << "   " << DY << endl;
	
	
	
	Image2D::Pointer PaddedImage=Image2D::New();
	Image2D::RegionType Region1;
	Image2D::IndexType index1=index;
	Image2D::SizeType size1={{DimX,DimY}};
	Region1.SetSize( size1);
	Region1.SetIndex(index);
	PaddedImage->SetLargestPossibleRegion(Region1);
	PaddedImage->SetBufferedRegion(Region1);
	PaddedImage->Allocate();
	PaddedImage->FillBuffer(0);
	IteratorType2D It( PaddedImage,Region1 );
	for(;!It.IsAtEnd();++It)
	{
		It.Set(0);
	}
	
	
	PastType::Pointer PastPadFilter =PastType::New();
	PastPadFilter->SetInput(PaddedImage);
	PastPadFilter->SetSourceImage(InImage);
	PastPadFilter->SetDestinationIndex( index1 );
	PastPadFilter->SetSourceRegion(Region);
	PastPadFilter->Update();
	PaddedImage=PastPadFilter->GetOutput();
	
	
	WriterType2D::Pointer writer1 = WriterType2D::New();
	writer1->SetFileName( Path1 );
	writer1->SetInput(PaddedImage );
	try
	{
		writer1->Update();
	}
	catch (itk::ExceptionObject & e)
	{
		std::cerr << "exception in file writer " << std::endl;
		std::cerr << e << std::endl;
	}
	
}
