[Insight-users] ManagedITK + vtkdotnet

[Dan Mueller]

Hi Gareth,

Sorry for the belated reply, I am overseas and out of the office at
the moment. As such I don't have access to all the relevant
information, but I'll try to give you a few pointers to get you
started before I take a closer look once back home.

You should be able to set the itkImage.Buffer value with the void
pointer from the vtkdotnet object. However, if memory serves me
correctly, you will have to ensure the itkImage is allocated (by
calling Allocate) before doing this.

Becuase of the interest in these classes, I will add them to the
enhancement list and give them high priority. However, I've got alot
on my plate at the moment, so don't expect them for a week or two. If
you can't wait and want to wrap them yourself, then let me know and I
can give you a few pointers when I've got the code base in front of
me.

BTW: If you are finding ManagedITK helpful, perhaps you can leave a
review at the Insight Journal, so the project can be improved. (Note
that the journal website is down at the moment, so you may have to
visit in a few days time when its back online.)
