[IGSTK-Developers] UMC in ImageSpatialObjectRepresentation

[Luis Ibanez]

Hi David,

Thanks for pointing this out.

The issue was entered in the bug tracker as Bug #2516
http://public.kitware.com/Bug/bug.php?op=show&bugid=2516&pos=0

and a fix has been committed in CVS:
http://public.kitware.com/cgi-bin/viewcvs.cgi/Source/igstkImageSpatialObjectRepresentation.txx?root=IGSTK&sortby=date&r2=1.12&r1=1.11

A test case was added to the file
igstkCTImageSpatialObjectReadingAndRepresentationTest

http://public.kitware.com/cgi-bin/viewcvs.cgi/Testing/igstkCTImageSpatialObjectReadingAndRepresentationTest.cxx?root=IGSTK&sortby=date&r2=1.4&r1=1.3

To test the behavior when an image from a non-updated reader
has been connected and when an image from an updated reader
has been connected.


   Thanks


      Luis
