[Insight-users] CheckerBoardImageFilter : SetCheckerPattern() / GetCheckerPattern() methods.

[Luis Ibanez]

Hi Emma,


These methods were added to ITK on May 25th 2005:
http://www.itk.org/cgi-bin/viewcvs.cgi/Code/BasicFilters/itkCheckerBoardImageFilter.h?rev=1.4&root=Insight&view=log


Please look at the Doxygen documentation of the CheckerBoardImageFilter.

You will find the methods:

GetCheckerPattern ()
http://public.kitware.com/Insight/Doxygen/html/classitk_1_1CheckerBoardImageFilter.html#itk_1_1CheckerBoardImageFilterz553_0

And

SetCheckerPattern ()
http://public.kitware.com/Insight/Doxygen/html/classitk_1_1CheckerBoardImageFilter.html#itk_1_1CheckerBoardImageFilterz553_1


You should use a type


              FilterType::PatternArrayType


as the argument to SetCheckerPattern()



Regards,


    Luis
