Hi Amir,
Thanks for letting us know about the details of the
myITKGui application.
This is not officially an application distributed with
"InsightApplications", so we cannot continuously test it.
The myITKGui is an example app, used for a course at
the University of Pittsburgh and Carnegie Mellon, by
the group directed by Dr. George Stetten. Details of
this course (and other ITK courses at graduate level)
are described in a paper published recently in the
Medical Image Analysis journal:
http://www.elsevier.com/wps/find/journaldescription.cws_home/620983/descriptionIf you take a look at the README.txt file that is
distributed with the application. You will find that it
was intended to be built with
ITK 1.8.1
FLTK 1.1.6
VTK 4.4
CMake 2.0
In order to build it with CMake 2.2, the CMakeLists.txt
file needs to be updated. In lines 70 and 71, the variables
myITKgui_VTK_SRCS
myITKgui_App_SRCS
must be surrounded by brackets and with the dollar sign,
just like:
${myITKgui_VTK_SRCS}
${myITKgui_App_SRCS}
after this...
The compilation problem that you are finding are related to
comparisons of the SmartPointers with the value "0".
The code in migAppBase.cxx uses lines such as
if( m_InputImage != 0 )
and
if( m_InputImage == 0 )
and
if( m_OutputImage == 0 )
That the compiler is misinterpreting as comparisons
between an ITK SmartPointer and an integer.
These lines should be replaced with:
if( m_InputImage.IsNotNull() )
if( m_InputImage.IsNull() )
(Note that IsNotNull() and IsNull() are methods
of the SmartPointer class, not of the Image class,
therefore you invoke them with the "." notation,
instead of the "->" notation.).
You could also use the more direct notation:
if( m_InputImage ) // test for non NULL
if( ! m_InputImage ) // test for NULL
although the one of (IsNotNull() and IsNull() ) is
the recommended one, because it is very clear,
explicit and self-documented.
Please make these changes in the code, and let us
know if you find any further problems.
Thanks
Luis
BTW: Note that the source code is copyrighted
by Damion Shelton, (who developed most of the
material). Before modifying the code and using
it, you should contact the copyright holders
and ask about the license that they are providing
for users (typical cases are GPL, BSD, MIT, ...
but it is really up to the copyright holder to
chose one).
Depending on the rules of the University, the
copyright may actually be held by the University
and not the be authors of the code. You will be
surprised of the things that you will learn if
you visit the Intellectual Property Office of
your university and ask a similar question.
Note also that the vtkFlRenderWindowInteractor
is distributed under a GPL license. Therefore
the source code of this app, is implicitly subject
to a GPL license too, and if you modify the code
or use it for your applications, then your code
is also subject to a GPL license.
For more details on Open Source Licensing, please
take a look at the Wiki page:
