Hello list,
first of all I want to give some props to the MITK makers for the new
release. The new features look promising. I came back to MITK after a
while of doing other work.
After compiling my application with the new MITK (0.9.3) I ran into a
problem though.
Loading a VTK file (VTK Dataset Structured Points, I attached the header
at the end of the mail) does not seem to work correctly. The image is
just a segmented volume with 0s, 1s and 2s. I am doing the following
(which worked with the older MITK):
// -- try to read the file
mitk::DataTreeNodeFactory::Pointer reader =
mitk::DataTreeNodeFactory::New();
try {
reader->SetFileName(filename.ascii());
reader->Update();
} catch(...) {
// some error handling...
return;
}
// -- open segmentation image
mitk::Image::Pointer segmentationImage =
dynamic_cast<mitk::Image*>(reader->GetOutput()->GetData());
if (segmentationImage.IsNull()) {
// some more error handling... is not reached in this case!!!
return;
}
The strange thing is that I do get a segmentationImage which is not
null. In debug mode I can see that the segmentationImage contains all
the correct dimension, spacing, etc. information, simply the image data
is missing (segmentationImage.m_CompleteData.m_Pointer=0x000000). This
naturally produces errors further down the pipeline.
Notice that when I use the Open dialog of the MainApp loading works
perfectly!
Any ideas what is going on here? Thanks in advance!
Cheers, Marcel
