[Insight-users] Converting a 2D slice to an image

[Karthik Krishnan]

Hi Tim,

Try using ExtractImageFilter since it takes two templated arguments and 
might server your purpose.

typedef itk::Image< char, 3 > Image3D
typedef itk::Image< char, 2 > Image2D
typedef itk::ExtractImageFilter<Image3D,Image2D> FilterType;

Use SetExtractionRegion method to set the dimension of the appropriate 
axis to 0 so as to extract slices perpendicular to that axis.

Hope this helps
thanks
