    139139=== Dataset.!ReadRaster, Dataset.!WriteRaster support ===
    140140
    141 Similarly to the Band.!ReadRaster band Band.!WriteRaster implementation the Dataset.!ReadRaster, Dataset.!WriteRaster is also supported for now. This implementation uses the same approach as described in [http://trac.osgeo.org/gdal/wiki/GdalOgrCsharpRaster GDAL/OGR Raster Operations]

    143143=== Added support for Dataset.!BuildOverviews (#1552) ===
    144144
     145The C# interface now supports the Dataset.!BuildOverviews function by creating typemaps for the integer array parameter. Currently the following signature should be used:
     146
     147{{{
     148public int BuildOverviews( string resampling, int[] overviewlist)
     149}}}
     150
     151The [http://trac.osgeo.org/gdal/browser/trunk/gdal/swig/csharp/apps/GDALOverviews.cs GDALOverviews.cs sample] demonstrates the usage of this function. The function uses the following commandline options:
     152
     153{{{
     154gdaloverviews {GDAL dataset name} {resamplealg} {level1} {level2} ....
     155}}}
     156
     157The created overview images can be extracted using the [http://trac.osgeo.org/gdal/browser/trunk/gdal/swig/csharp/apps/GDALRead.cs GDALRead.cs] or the [http://trac.osgeo.org/gdal/browser/trunk/gdal/swig/csharp/apps/GDALReadDirect.cs GDALReadDirect.cs] examples using the following commandline options:
     158
     159{{{
     160gdalread {GDAL dataset name} {output file name} {overview_level}
     161}}}
     162
     163
    145164=== Examples added ===
     165
     166Along with the aforementioned [http://trac.osgeo.org/gdal/browser/trunk/gdal/swig/csharp/apps/GDALOverviews.cs GDALOverviews.cs sample] the [http://trac.osgeo.org/gdal/browser/trunk/gdal/swig/csharp/apps/GDALInfo.cs GDALInfo.cs sample] has also been added for demonstrating the various operations of the GDAL related functions.
