[Insight-users] Is there any itk::BoundingBox example?

[Luis Ibanez]

Hi Juliette,

Here are three options for you to get the file
of this new example:

A)  Do a CVS checkout of ITK
     http://www.itk.org/ITK/resources/software.html

or


B)  Get the file through the Web CVS interface:
http://public.kitware.com/cgi-bin/viewcvs.cgi/Examples/SpatialObjects/BoundingBoxFromImageMaskSpatialObject.cxx?root=Insight&sortby=date&sortdir=down&view=log
you could use this direct link:
http://public.kitware.com/cgi-bin/viewcvs.cgi/*checkout*/Examples/SpatialObjects/BoundingBoxFromImageMaskSpatialObject.cxx?revision=1.1&root=Insight


or


C) Get it as the attachment of this email     :-)



     Regards,


              Luis
