[Insight-users] ITK-VTK image and problems with includes in visual c++ express 2008

[Matthieu Duvinage]

Hello everybody,

I'm working on a project in the medical field and I'm using VTK. 
However, the last module I have to create seems to be provided only by 
ITK. In fact, I have to transform a volume in a series of PNG files and 
the ImageSeriesWriter class seems to be devoted to that.

1) I have compiled the library with CMake and then done the build all 
and install process. I put the repertories in includes and librairies in 
visual studio express 2008 but I have a problem. The program says that 
the file I have to import is not in the directory whereas it is but in a 
deeper directory. I have again this problem when I put the deeper 
directory in the include directories with another file. Is it possible 
to enable an option in visual to force it to look in deeper directories ?
2) I would like to use the  normals image (see below) from a VTK class 
to use ImageSeriesWriter. Could you give me an example of how to use 
that ? Because I'm a bit lost with all the classes and the principle of 
pipeline. I have seen that there exist VTKimport or export classes to do 
something in this case but how do I have to do ?

I hope I hear from you soon
