[Insight-users] ImageReadWrite and Tif

[Luis Ibanez]

Hi Michael,


Yes, the example


   Insight/Examples/IO/
              ImageReadWrite.cxx


is using "unsigned char" as pixel type.
It will  convert color images into grayscale
(not bitonal...) at read time and then save
them again as a agrayscale image.


What you need for managing color images is
a pixel type such as:

    itk::RGBPixel< unsigned char >

or

    itk::RGBAPixel< unsigned char >


The example that you want to use is:



     Insight/Examples/IO/
                 RGBImageReadWrite.cxx



Regards,



    Luis
