[Insight-users] Convert a set of 2D images to 3D

[Luis Roberto P. Paula]

Hi Luis,

I'm a little confused on how to use the itkPasteImageFilter.

At first, I created the typedef:

typedef itk::PasteImageFilter< ImageType2D > PasteFilter2D;


Then:

   PasteFilter2D::Pointer paste2D = PasteFilter2D::New();

   // I'm lost in this part

   for (int i; i < VECTOR_SIZE; i++) {
      paste2D->SetInput( IMAGE2D_VECTOR[i] );
   }

How do I make the output of the paste2D be a 3D image?

Do I need to set to the destination image a 3D blank image?

The destination index affects the output?

I thought it would work like the add method of the std:vector class with an
output as a 3D image, but it seems that it can return an image with the same
dimension.

Thanks,
Luis
