[Insight-users] Cannot debug projects of ITKApplication.

[Luis Ibanez]

Hi Jimmy,

You should have mentioned from the beginning that you
were attempting to read a RAW image file.


        You *CANNOT* read a RAW image file
        directly with the ImageFileReader.



You have the following options:

  a) Create a MetaImage header for the RAW file.
  b) Use explicitly the RAWImageIO class in your code.


>From these two options, method (a) is the recommended one
because method (b) results in hard-coding the image
parameters in your program.


The easiest way of creating a MetaImage header for your
raw image is to use the program:


   InsightApplications/MetaImageImporter


It is a command-line dialog that will guide you through
the process by asking you questions about your image.


The filename extension of your MetaImage header must be
".mhd".

Once you have created this header, you can pass it as
the filename to be read by the ImageFileReader.


   Regards,


      Luis
