[vtkusers] Vsacular multiframe images

[Kulkarni, Smita (MED)]

Hi all,
I need help in viewing a multi-frame image using VTK. The following program
shows the first frame all the time. I am not able to view the subsequent
frames. I am able to view a range of single-frame images using a similar
program however. Please advise.

#include < vtkVolume16Reader.h>
#include < vtkImageViewer.h >
void main()
{
vtkVolume16Reader *reader = vtkVolume16Reader ::New(); //object declaration
reader->SetDataByteOrderToBigEndian();	// Byte Declarartion
reader->SetHeaderSize(0);		// Header Size
reader->SetDataDimensions(1024,1024);	// Width & Height	
reader->SetFilePrefix ("e:\\im\\record_for_DSA_massy"  );	// File Path
reader->SetFilePattern( "%s");	// File pattern	
vtkImageViewer  *viewer= vtkImageViewer::New();
viewer->SetInput (reader-> GetOutput());	//pipline pass data to
mapper
viewer->SetColorWindow(1000);		// Brightness
viewer->SetColorLevel( 512);		// contrast	
viewer->Render();
getchar();
for (int i = 0; i < 12; ++i)		// 12 frame image
    {
    // next image
    viewer->SetZSlice( i );
    // render the image
    viewer->Render();
    }

getchar();
reader->Delete();
viewer->Delete();
}

Thanks a lot,
Smita.
