[Debian-med-packaging] Bug#1012691: nifti2dicom: Migration from vtk7 to vtk9

[Francois Mazen]

Package: nifti2dicom
Severity: wishlist
Tags: patch
X-Debbugs-Cc: francois at mzf.fr

Dear Maintainer,

nifti2dicom package depends on vtk7 which is quite old and not maintained
upstream.

I've succeeded to build nifti2dicom with vtk9 by changing Build-Depends from
libvtk7-qt-dev to libvtk9-qt-dev and changing the QVTKWidget to
QVTKOpenGLNativeWidget class in src/gui/init.
A simple patch is attached to this message.

Could you please look at the patch and update to vtk9?

Thanks,

François
