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

[Elvis Dowson]

Hi,
        I got some output, but don't know what to make of it?

vtkImageReader2 reader
   reader SetFileName "/Users/elvis/Repository/Data/NASASRTM/version2/ 
SRTM3/Eurasia/N25E070.hgt"
   reader SetHeaderSize 0
   reader SetDataByteOrderToBigEndian
   reader FileLowerLeftOn
   reader SetDataScalarTypeToInt
   reader SetFileDimensionality 2
   reader SetDataExtent 0 200 0 200 0 0

vtkImageViewer2 viewer
viewer SetInputConnection [reader GetOutputPort]
viewer SetColorWindow 256
viewer SetColorLevel 127.5

The image data is 1201x1201 array using 16-bit signed integers, but it  
kept crashing when I use SetDataExtent 0 1201 0 1201 0 0.


Best regards,

Elvis Dowson
