You are right that the label maps could have chosen to use an outline for the geometrical representation. However we haven't implemented that. Also, with an outline, things can get very confusing at the interface between adjacent segmentations.

The paintbrush widget invokes events during and after interaction, that you can observe. You can query the image data from the drawing, (which is maintained by the representation). (See examples/ tests that save the edited data out). I'd have liked to see a 3D (passive) representation written that does this automatically, to make it easy for users. However we never had the time. One nice thing with the grayscale data is that it should already give you smooth contours. > > Can I still use Label DataType to achieve this goal? > no. > > > Regards, > > JK > > > > > > *From:* Karthik Krishnan [mailto:[email protected]] > *Sent:* Tuesday, September 15, 2009 12:07 PM > *To:* Kim, Jinkoo > *Cc:* [email protected] > *Subject:* Re: [VtkEdge] segmentation displayed as contour outlines not > filled-solid color. > > > > You would need to take a look at VTKEdgePaintbrushExample4.
