[vtkusers] problem of re-rendering image that has been shrinked

[Thomas Guiot]

hi ,
 
i'm having some trouble displaying an image that has been shrinked...
i have a created a GUI letting me load and display images and perform some processing as well...
here's my problem:
i load an image (and display it for the first time), then shrink it with itkShrinkImageFilter, and when i try to render the shrinked image, i get this message :
 
ERROR: In ..\..\VTK\Filtering\vtkStreamingDemandDrivenPipeline.cxx, line 698
vtkStreamingDemandDrivenPipeline (06386038): The update extent specified in the information for output port 0 on algorithm vtkImageMapToWindowLevelColors(06384C30) is 0 310 0 348 0 0, which is outside the whole extent 0 154 0 173 0 0.
 
and of course, this triggers a breakpoint, and i don't know what to do...
 
 
 
any idea?
 
thanks,
 
 
thomas.
