[vtkusers] How to import NASA SRTM DEM data into VTK

[Elvis Dowson]

Same error and image when I set the data extent to

reader SetDataExtent 0 1200 0 1200 -32767 32767

elvis-dowsons-macbook-pro:~ elvis$ wish
% Generic Warning: In /Users/elvis/Tool/vtk-5.x/src/VTK/IO/ 
vtkImageReader2.cxx, line 775
File operation failed. row = 600, Read = 4804, FilePos = -1

Best regards,

Elvis Dowson
