[vtk-developers] vtkWriter and vtkImageWriter

[Andy Cedilnik]

Hello!

After careful observation, you will notice that all writers do not have
the same parent class, but use some of the same interface.
For example:

vtkStructuredPointsWrite is a subclass of vtkWriter, which provide some
functionality including:

	Set/GetFileName
	Set/GetInput
	Write

vtkPNGWriter on the other hand is a subclass of vtkImageWriter, which
provides different functionality but also provides interface for:
	
	Set/GetFileName
	Set/GetInput
	Write

So, how about either make vtkImageWriter a subclass of vtkWriter or
add additional parent class for both types of writers?
