[vtkusers] vtkImageReader->Update causes Runtime error....why?

[Giancarlo Amati]

Hi yes sure this is the function compiled under Visual Studio 2005 and QT:


void CMainWindow::renderGIPL(QString *filename){
    double dr = 250.0/255.0,db = 250.0/255.0,dg = 240.00/255.0;

    QByteArray temp = filename->toAscii(); 
    char *data = temp.data(); 
    
    vtkImageReader *VtkGiplReader = vtkImageReader::New();
    VtkGiplReader->SetFileName(data);
    VtkGiplReader->Update();

    vtkImageData *m_vtkImgDATA  = VtkGiplReader->GetOutput();
    double isovalue = computeIsoValue(m_vtkImgDATA);

    vtkImageMarchingCubes *iso = vtkImageMarchingCubes::New();
    iso->SetInputConnection(VtkGiplReader->GetOutputPort());
    iso->SetValue(0,isovalue);
    iso->ComputeGradientsOff();
    iso->ComputeScalarsOff();

    vtkPolyDataMapper *isoMapper = vtkPolyDataMapper::New();
    isoMapper->SetInputConnection(iso->GetOutputPort());
    isoMapper->Update();

    vtkLODActor *isoAct = vtkLODActor::New();
    isoAct->SetMapper(isoMapper);
    isoAct->SetUserMatrix(this->registrationMatrix);
    (isoAct->GetProperty())->SetColor(dr,db,dg);

    _ren->AddActor(isoAct);


    QTreeWidgetItem *child = new QTreeWidgetItem();
    child->setText(0,fileNamePath);
    child->setIcon(0,QIcon(QString(tr("../icons/bullets/model.png"))));

    _ui->treeWidget->topLevelItem(0)->addChild(child);


    isoAct->Delete();
    isoMapper->Delete();
    iso->Delete();

}

Hello everybody,

this is my code, simple and easy:

vtkImageReader *img = vtkImageReader::New();
img->SetFileName(fn);
img->Update();

dunno why but it causes this RunTime Error: "The value of ESP was not properly saved across a function call. This is
usually a result of calling a function pointer declared with a
different calling convention".

Anybody has any idea about it?

Kind Regards.
GC.


Can you upload the vti file in question somewhere? Then at least I can confirm the behavior.

Thanks,

David
