[Insight-users] Get the data buffer of itk::Image?

[Luis Ibanez]

Hi Feng,


You can get the buffer from the itk::Image
http://www . itk . org/Insight/Doxygen/html/classitk_1_1Image . html



by using the method

        GetBufferPointer()

http://www . itk . org/Insight/Doxygen/html/classitk_1_1Image . html#z839_0
It will return a raw pointer to the pixel type.



You could also use the method

        GetPixelContainer()

http://www . itk . org/Insight/Doxygen/html/classitk_1_1Image . html#a11
That returns the intermediate class holding the buffer.



Regards,


   Luis
