Where is struct MenuItem defined? Perhaps you need to include another header file.

Presumably you were able to sort this out.

Will you take a moment to show the rest of us what the solution was?

Hi guys, I'm using a simple gdal script to load topography data from a .DEM file to a grid. However, when I do this gdal converts the data into 16 bit unsigned integers, which is no good for reading negative elevation. I though I told it to read the data as 32 bit floats, but it reads as uint16, then converts to float32. Here is my code: import gdal from gdalconst import * import numpy data = gdal.Open(topoFile,GA_ReadOnly)
