0013212: vtkMaskPoints: bad initialisation of MaximumNumberOfPoints
I am using vtk 6.0

MaximumNumberOfPoints is being initialised to VTK_LARGE_ID, this should be initialised to VTK_LARGE_INT instead. See line 36 of vtkMaskPoints.cxx.
Also VTK_LARGE_ID should be changed to VTK_LARGE_INT in the clamp macros at lines 49, 54 in vtkMaskPoints.h

Rationale:
This code will crash in Python:
mask.SetInputConnection(parametricFunctionSource.GetOutputPort())
print vtk.VTK_LARGE_ID, vtk.VTK_LARGE_INTEGER
print mask.GetMaximumNumberOfPoints()
#mask.SetMaximumNumberOfPoints(100)
mask.RandomModeOn()

with the error:
ERROR: In c:\users\amaclean\code\kitware\src\vtk\common\core\vtkDataArrayTemplate.txx, line 144
vtkFloatArray (000000000278C110): Unable to allocate 9223372036854775805 elements of size 4 bytes.

Obviously uncommenting:
#mask.SetMaximumNumberOfPoints(100)
will fix this.

This issue probably only arises in 64-bit systems.
No tags attached.
