[Insight-users] file reader

[Luis Ibanez]

Hi Gwenael,


Did you call "Update()" on the reader ?

The output of filters is not valid until
an Update() call has been issued on them.
Please make sure that you call "Update()"
before calling "GetOutput()" on a reader.

You will find many examples of Read/Write
operations in the Insight/Examples directory.

In particular on the directories:

    Examples/Filtering
    Examples/IO


You may also want to take a look at the
SoftwareGuide.pdf document:
http://public.kitware.com/Insight/Web/HTML/SoftwareGuide.pdf

In particular the chapters:

- "Filtering"
- "Reading and Writting Images"


Please let us know if you have further questions,


   Thanks


     Luis
