[vtkusers] Picking a point on an image and change it's color!

[John Smith]

Hi,

As I don't have a lot of experience in VTK, I need some help. I want to have a function to pick a point on an image and change the color of that pixel once it is picked. I found some functions but it's not working with images. Can someone help in that by providing a simple C++ code or directing towards the write class(es) to be used?

Thanks,

J.

P.S. I'm using:
QVTK
VTK5
QT4
for reading and visualizing the images:
vtkDICOMImageReader
vtkImageViewer2
