[Insight-users] SignedDanielssonDistanceMapImageFilter runtime error

[Luis Ibanez]

Hi Leonid,

Thanks for the detailed description of your problem.

The most likely source of the problem is that you may be using
PNG as the output file format for the distance image.



       PNG does not support pixel type "float".



Please use formats such as

   * MetaImage
   * VTK

as output file formats.

For example:

SignedDanielssonDistanceMapImageFilter
   Circle.png CircleDistanceMap.mha voronoiMap.mha vectorDistance.mha

(in a single command line)

or

SignedDanielssonDistanceMapImageFilter
   FivePoints.png FivePointsDistance.mha FivePointsVoronoi.mha
                  FivePointsVector.mha



I just run these two examples with the Nightly build of
ITK and obtained the expected results.


You can view the MetaImage output by using

   a) Slicer
   b) ParaView
   c) SNAP
   d) ImageViewer (from InsightApplications)


Please let us know if you have any questions.


    Thanks


       Luis
