[vtkusers] Problem vtkImageMapToColors and vtkImageBlend

[Paulo Henrique Junqueira Amorim]

Hi!

I've build a pipeline using vtkImageMapToColors and vtkImageBlend and it
works fine. However, when a large vtkImageData [such as 3] is used as input
and "Update()" is called in one of these classes, my application is
interrupted.

This problem occurs only under Windows (tested under XP Professional SP).
The same pipeline and input worked under Linux (Ubuntu and Fedora) and Mac
OS X (Leopard).

I'm using VTK 5.2 and I've written the code both in Python and C++. In the
first case the error message was [1] . In the second case, the error message
was [2].

Is there a way of processing parallely these filters? I need to load and
manipulate all this data at the same time.

Thanks!

Paulo
