[gdal-dev] GDALDEMProcessingOptionsNew with NULL psOptionForBinary

[jsherm]

Amusingly stumbled across this same problem this morning.  When working with
GDAL python 64 bit I cannot pass any altitude argument to
gdal.DEMProcessing() for hillshade.  Other arguments work fine, or if I set
the altitude argument = None it also functions.  However, I obviously would
prefer to use the altitude argument for hillshade.



Hillshade = gdal.DEMProcessing('hillshade.tif', DEM, 'hillshade',
combined=True, format = 'GTiff', altitude = 51, azimuth = 158)

returns the error:
Traceback (most recent call last):
  File "C:/DSWE_V2/DSWE_V2_P1_GDAL_distro_v2_dev.py", line 192, in <module>
    Hillshade = gdal.DEMProcessing('hillshade.tif', DEM, 'hillshade',
combined=True, format = 'GTiff', altitude = 51, azimuth = 158)
  File "C:\Python_64bit\lib\site-packages\osgeo\gdal.py", line 792, in
DEMProcessing
    return DEMProcessingInternal(destName, srcDS, processing, colorFilename,
opts, callback, callback_data)
  File "C:\Python_64bit\lib\site-packages\osgeo\gdal.py", line 2976, in
DEMProcessingInternal
    return _gdal.DEMProcessingInternal(*args)
TypeError: in method 'DEMProcessingInternal', argument 5 of type
'GDALDEMProcessingOptions *'

Thanks all
