Hi all,
I am trying to use an itk pipeline into a vtk pipeline. One example is =
given in:
InsightApplications-1.2.0\Auxiliary\vtk\itkPNGVTKtoITKtoVTK.cxx
It works well with the provided images because they have the same size. =
But if you replace the second png image with a smaller one
the program crashes telling that the update extent is to large.
1) Bypassing the itk part of this example doesn't solve the problem. To =
solve that, You remove the first vtk actor and then create a new one and
display it as usual. With this modification le vtk pipeline works well =
when the second image is smaller.
2) But, with the previous vtk modifications, if I re-activate the itk =
pipeline, the bug re-appears.=20
Is it a pb with the itk pipeline ? or with the vtk/itk importer/exporter =
connections ? it seems that the update extents are not
correctly transmitted through the pipelines connections when an upate is =
requested....
Thanks for answers
Christophe
