NaN values not being parsed in gdal_rasterize options

Reported by: dsogari Owned by: warmerdam
Priority: normal Milestone: 2.0.3
Component: default Version: svn-trunk
Severity: normal Keywords: gdal_rasterize nan


The gdal_rasterize app currently does not handle NaN values for the "-init" and "-burn" options, because of the implementation of the ArgIsNumeric function in gdal_rasterize_lib.cpp::47

If we supply such value, ArgIsNumeric gives false and the 'i' is not incremented when reading either the "-init" or "-burn" options, causing the app to fail in the next iteration.

I propose the following modification: where it reads

   return CPLGetValueType(pszArg) != CPL_VALUE_STRING;

it could be written

   return CPLIsNan(CPLAtof(pszArg)) ||
       CPLGetValueType(pszArg) != CPL_VALUE_STRING;

A patch file is attached for convenience. Thanks
