[vtkusers] Writing a JPEG from vtkActor

[Marlos Fabris]

Hi,

I'm trying to write a jpeg file (using vtkJPEGWriter) from a vtkActor
but I can't accomplish this. I have a vtk file with structured points
data and I wish to transform to vtkPolyData and color it with my
vtkLookupTable.

Is there a way to convert only my vtkActor to a vtkImageData, without
the frameborders of vtkWindowToImageFilter?

Or is there a way to trim my image?

Thank you in advance,
