[Insight-users] How to get one 2d image from 3d volume data?

[Luis Ibanez]

Hi Chunyan,

Please look at the itk::ExtractImageFilter
http://www . itk . org/Insight/Doxygen/html/classitk_1_1ExtractImageFilter . html

an example on how to use this filter is available at

Insight/Examples/IO/
                ImageReadExtractWrite.cxx

You can actually use this demo application as a command
line tool for extracting slices from a volume.

In your case, you are probably more interested in
copy/pasting the core code from the example into your
application.


Regards,


    Luis
