Summary

0001859: VTK pipeline / Extent broke apps

Description

This script used to work in VTK 4.4:

package require vtk
# Image pipeline
vtkBMPReader reader
reader SetFileName "$VTK_DATA_ROOT/Data/masonry.bmp"
#vtkImageViewer viewer #seems ok
vtkImageViewer2 viewer
viewer SetInput [reader GetOutput]
vtkRenderWindowInteractor iren
viewer SetupInteractor iren
iren Initialize
iren Start
wm withdraw .

Now it returns:

ERROR: In VTK/Filtering/vtkImageData.cxx, line 1475
vtkImageData (0x81ac1a0): GetScalarPointer: Pixel (0, 0, 0) not in memory.
Current extent= (0, -1, 0, -1, 0, -1)

Notes
(0002421) Mathieu Malaterre (developer) 2005-05-16 16:47	If you replace vtkImageViewer2 with vtkImageViewer the tcl script runs fine. vtkBMPReader still uses ExecuteInformation/ExecuteData

(0002423) Mathieu Malaterre (developer) 2005-05-16 17:09	Brad did a research and found out that vtkImageData::GetScalarPointer direclty uses this->Extent without making sure this is up to date
