I am trying to use the OSGeo.GDAL.Gdal.RasterizeLayer(…) from GDAL 1.9.2 and it requires some SWIGTYPE parameters:

OSGeo.GDAL.Gdal.RasterizeLayer(
    OSGeo.GDAL.Dataset dataset,
    int bands,
    OSGeo.GDAL.SWIGTYPE_p_int band_list,
    OSGeo.OGR.Layer layer,
    OSGeo.GDAL.SWIGTYPE_p_void pfnTransformer,
    OSGeo.GDAL.SWIGTYPE_p_void pTransformArg,
    int burn_values,
    OSGeo.GDAL.SWIGTYPE_p_double burn_values_list,
    string[] options,
    OSGeo.GDAL.Gdal.GDALProgressFuncDelegate callback,
    string callback_data
);

Reading up on some old mails somewhere (I've lost the link) regarding ReadRaster and WriteRaster in the C# bindings, Tamas Szekeres states that methods requesting SWIGTYPE parameters, cannot be used (yet).

Question:
Does this mean that the RasterizeLayer method hasn’t been ported to the C# bindings or are there some clever way to utilise this method?

SWIG Interface file Operations.i and generated files for csharp in gdal-1.9.1/swig/csharp/gdal/Gdal.cs says that they are available in GDAL C# bindings. Could you please tell what error exactly are you getting when performing rasterization.?

I have no idea about how to use the SWIGTYPE parameters, what to initialise them with and so on. – Chau Nov 2 '12 at 10:01
SWIGTYPE_p_int is an int array in c# and SWIGTYPE_p_double is double array. so for OSGeo.GDAL.SWIGTYPE_p_int band_list you can provide c# array of int[] try this and see what error you are getting – rashad Nov 3 '12 at 6:18
Can you give me an example of how to initialize and what to provide one of the SWIGTYPE parameters with? – Chau Nov 7 '12 at 13:22
try C# int where it asks for SWIGTYPE_p_int. i dindt tried myself. Maybe there is a better solution. But there is no harm in trying this – rashad Nov 11 '12 at 10:20
