[vtkusers] colour jpg image with vtkJPEGwriter

[Adam G Chandler]

Hi all.

I have written a program which reads in a
matrix of numbers, fills a vtkImageData object with the values from
the matrix, and then writes this object out as a jpg with
vtkJPEGWriter.

At presnt the jpg image that i get out is only in a black and white
scale. Is there some way that i can apply a colour lookup table to the
jpg image, so that the scale is between red (for high values) and
blue(for low values) for example? 

Thanks in advance

Adam
