Re: [vmtk-users] vmtk - getting started

[Luca A. <luc...@gm...>]

Hi cq,
 the fact that python crashes is not normal, and very likely you won't solve your problem by using the C++ directly.

You may want to first try out the both possible ways of reading DICOM files in vmtk:

the first is 
vmtkimagereader -f dicom -d directory_with_dicom_files_in_it

and the other is
vmtkimagereader -ifile first_dicom_file_in_your_series.dcm

The first uses vtkvmtkDICOMImageReader, while the second uses the ITK I/O mechanisms (which rely on GDCM, a dicom library).

In any case, using a class from vmtk in C++ is no different than using a VTK class from C++, since all vmtk classes are derived from VTK.
For the parameters to set, you can directly refer to how they are used in vmtkimagereader.py.
In order to bulid against vmtk, just include the VMTKUse.cmake file that is in the bulid directory (or in the install directory) in your CMakeLists.txt 
file to successfully compile against vmtk. If you don't know about CMake or VTK, please refer to the relative manuals and mailing lists.

Let me know if you need further directions

Luca
