[wxVTK] vtkDICOMImageReader does not display images - VTK 5.0

[Andres M. <mun...@gm...>]

>> Hello everyone,
>> I'm trying to read DICOM images using the vtkDICOMImageReader and  
>> display it in a wxWidgets window.  Everything seems to be working  
>> ok except that the image isn't displayed at all.  If I call the  
>> viewer->Render() method a new window is opened but the image isn't  
>> displayed either.  I'm running MacOSX 10.4.  I believe the code is  
>> fine.
>> The following snippet is used to construct the wxWidget frame to  
>> display the file (or series)
>> ImageFrame::ImageFrame(wxMDIParentFrame *pp_Parent, const  
>> wxString& p_strTitle, const wxPoint& p_Pos, const wxSize& p_Size,  
>> const long p_lStyle):wxMDIChildFrame(pp_Parent, -1, p_strTitle,  
>> p_Pos, p_Size, p_lStyle | wxNO_FULL_REPAINT_ON_RESIZE)
>> {
>> vtk_interactor = new wxVTKRenderWindowInteractor(
>> this, MDI_VTK_MINI_WINDOW);
>> vtk_interactor->UseCaptureMouseOn();
>> viewer = vtkImageViewer2::New();
>> viewer->SetupInteractor(vtk_interactor);
>> viewer->SetColorWindow(WINDOW_VALUE);
>> viewer->SetColorLevel(LEVEL_VALUE);
>> }
>> bool ImageFrame::OpenSeries(wxString path)
>> {
>> atImage = fachade->srvOpenSeries(path);
>> viewer->SetInput(atImage);
>> viewer->SetupInteractor(vtk_interactor);
>> // viewer->Update();
>> // viewer->Render();
>> return (atImage != NULL);
>> }
>> the Fachada object returns a vtkImageData* after calling the  
>> ImageProcessingCore OpenSeries method.
>> vtkImageData* ImageProcessingCore::OpenSeries(const char* path){
>>      reader->SetDirectoryName(path);
>>     reader->Update();     return reader->GetOutput(); } thanks for  
>> your help in advance,
