[vtkusers] writing a custom image loader

[Oliver Kania]

Hello and thanks,
We have points in the eucledian plane which are arranged like a regular
grid.
(evenly spaced)
We have a measured value for each point that should be interpreted as a
grey-scale or color
value.
How do I tie this to a vtkImageData ?

best regards,
Oliver

PS: we already ordered both VTK-books.
