[Insight-users] Image Scaling

[Dan Mueller]

Hi Himadri,

Not only does ITK allow for "zooming", but it provides a mechanism for 
generic geometric transformations.

Please read about the ResampleImageFilter in the ITK Software Guide 
(around section 6.9.4):
    http://www.itk.org/ItkSoftwareGuide.pdf

An appropriate transform for your particular problem is either the 
ScaleTransform or the AffineTransform. The ResampleImageFilter also 
expects an image interpolator, some common options are 
NearestNeighborInterpolateImageFunction, or 
LinearInterpolateImageFunction. See the image interpolators group in the 
documentation for more options: 
http://www.itk.org/Doxygen/html/group__ImageInterpolators.html

Cheers, Dan
