[Paraview] CSV Data using extra fields.

I have a file that looks like this:
x y z r g b px py

-2.064749 -1.623789 5.264024 254 254 254 5.000000 7.000000

-2.267242 -1.790226 5.803583 254 254 254 5.000000 8.000000

-2.251401 -1.784915 5.786366 254 254 254 5.000000 9.000000

-1.401535 -1.134097 3.676532 201 201 201 5.000000 14.000000

-1.420374 -1.154109 3.741410 179 179 179 5.000000 15.000000

...

In ParaVew, I use the inbuilt CSV reader and get a table of labelled columns.
In order tot get the points, I use a TableToPoints filter.
The output of this filter is a table consisting of r,g,b, px, py,
points, point ID.
This plots OK in 3D.

How can I transform the r, g, b arrays into a vtkUnsignedCharArray in
order to add colour information to the points?
I have been trying to use a programmable filter but don't seem to be
able to access the r, g, b components.
Also will the other components of the array be passed through, namely
(points, and px, py)? Ultimately I want to create a 2d image of the
px, py and colours.



Any help appreciated.

Thanks
   Andrew
