Summary0001641: bug in vtkImageviewer2 when one of the image dimension exeeds 512!!!
Descriptionalready posted a mail concerning this problem but now I am quite sure that the problem is in the class vtkImageViewer2. This class cannot display images when either the width or the height exceeds 512!!

Below is my code and attached a stack of MRI images..

you will notice the following:

1. With vtkImageViewer2, the display is not corret (the second dimension of the image is 611)

2. If you use vtkImageViewer instead of vtkImageViewer2, it will properly..( Strange! isn't it?)

3. Another remark, if you replace i by 5 for example or any number less than dim[2], and if you set up a breakpoint after viewer->Render(), you will notive that the first display is done properly, then if you continue inside the "while", the same image will not be displayed properly...

Hope all these information will help vtk developers to find the bug and help me because I spent so many time in debugging my program thinking that the bug was from me...

Thanks in advance

memmove(vol1, (unsigned char *)dcm_volume->GetScalarPointer()+i*(dim[0]*dim[1]),dim[0]*dim[1]);


vtkImageImport *importer_pro=vtkImageImport::New();

importer_pro->SetWholeExtent(0,dim[0]-1,0,dim[1]-1,1,1);

importer_pro->SetDataExtent(0,dim[0]-1,0,dim[1]-1,1,1);

importer_pro->SetDataSpacing(1,1,1);

importer_pro->SetDataOrigin(0, 0,0);

importer_pro->SetDataScalarType(VTK_UNSIGNED_CHAR);

importer_pro->SetNumberOfScalarComponents(1);

importer_pro->SetImportVoidPointer((unsigned char *) vol1);

importer_pro->Update();


viewer->SetSize(500,500);

viewer->SetInput(importer_pro->GetOutput() );

viewer->SetZSlice(1);

viewer->SetColorWindow(255);

viewer->SetColorLevel(127.5);

viewer->Render();

i++;

delete [] vol1;

importer_pro->Delete();

}
