[Paraview-developers] How can I get a proper vtk reader class from a filename with extension

[Jonathan Borduas]

Hi Paraviewers,

Got a bit of a challenge here.

I'm trying to create a plugin with a custom reader, that is subclass of a vtkMetaReader, so it can read any file via readers registered with ParaView.

All the implementations I saw use a If statement:

https://github.com/Kitware/ParaView/blob/b41d27999a4ac854f4a0e61d98d09c53e7583a60/ParaViewCore/ClientServerCore/Default/vtkNetworkImageSource.cxx

But I would like to have something in sync with the available readers.

For now I use something similar to:

const char *readerName = readerFactory->GetReaderName();
vtkObject *object = vtkObjectFactory::CreateInstance( readerName );[https://www.upwork.com/messages/rooms/room_38bea0513672a1d805f45ad03c83519e]

But for a .PNG file I receive as readerName "vtkImageFileSeriesReader" instead of "vtkPNGReader".

So basically my question is:

How can I get a proper vtk reader class from a filename with extension?

Thank you very much,
