[vtkusers] Writing a JPEG from vtkActor

[Dominik Szczerba]

What is the error? I try to do the same with vtkPNGWriter ending up with:

vtkPNGWriter (0x8058948): PNGWriter only supports unsigned char and
unsigned short inputs

Meanwhile I try to figure out how to do the appropriate convertion in vtk.
