[vtkusers] Problem while getting input to the ImageDataGeometryFilter

[Uma Sindhura]

Hi Friends,
 
I wanted to read a volume and save it as vtk and stl files.In the following application while I was debugging while setting the output of ImageImport to the input of ImageDataGeometryFilter ,I was not getting anything to the i/p of imagedatageometry filter.And while writing to vtk and stk I was getting access violation problem.Please help?
 
 
 
 
 
void convert1::image(CS_Volume* vol1,LPCTSTR Out_path1,LPCTSTR Out_path2)
{
 
  vtkImageImport* imageim=vtkImageImport::New();
 vtkImageDataGeometryFilter* gfil=vtkImageDataGeometryFilter::New();
 imageim->SetImportVoidPointer((void*)vol1,1);
 imageim->SetDataExtent(0,127,0,127,0,1);
 imageim->SetWholeExtent(0,127,0,127,0,1);
 imageim->SetDataSpacing(2.73,2.73,2.73);
 imageim->SetDataOrigin(0.0,0.0,0.0);
 imageim->SetDataScalarTypeToUnsignedShort();
 gfil->SetInput(imageim->GetOutput());
 vtkPolyDataWriter* vw=vtkPolyDataWriter::New();
 vtkSTLWriter* stl=vtkSTLWriter::New();
 ofstream ofile1; 
 ofile1.open(Out_path1,ios::in | ios::out | ios::binary);
 vw->SetInput(gfil->GetOutput());
 vw->SetFileName(Out_path1);
 vw->SetFileTypeToBinary();
 vw->Write();
 ofstream ofile2;
 ofile2.open(Out_path2,ios::in | ios::out | ios::binary);
 stl->SetInput(gfil->GetOutput());
 stl->SetFileName(Out_path2);
 stl->Write();
}
