[vtkusers] ROI using vtkImageTracerWidget

[Sercani]

Isn't there anyone who did this before? I have implemented
vtkImageTracerWidget example code to my project but i couldn't get the image
region inside this closed spline.

Thanks already, yours sincerely.

Hi everyone;

I am using vtkImageTracerWidget to draw freehand drawings on a vtkImageActor
(input of this actor is output of the vtkDICOMImageReader). I want to use
this closed spline for calculating the region area(using the spacing of
dataset too) and clip this region from image. I have looked at and tested
this example
http://public.kitware.com/cgi-bin/viewcvs.cgi/*checkout*/Examples/GUI/Tcl/Im
ageTracerWidget.tcl?root=VTK
<http://public.kitware.com/cgi-bin/viewcvs.cgi/*checkout*/Examples/GUI/Tcl/I
mageTracerWidget.tcl?root=VTK&content-type=text/plain>
&content-type=text/plain but couldn't get things clear. How can i get the
region boundaries and use it for area calculating and clipping image?

Yours sincerely;

Sercani..
