[vtkusers] Large Image rendered white?

[Robert Mitchell]

Dear Users,

I am reading in a large (10MB) Bitmap (vtkBMPReader) and rendering it
with a vtkImageActor having been passed through vtkImageLuminance  (see
previous message re:Dynamic Pipeline changes). The problem is that the
whole image is rendered completely white, although when I clip the data
and only render the clipped extent, it does it properly. Is there some
limit on the size of the extent to render properly, or is there some
caching things that need to be attended to?
Cheers,
Rob
