v7 v8 139 139 === Dataset.!ReadRaster, Dataset.!WriteRaster support === 140 140 141 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]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 CSharp Raster Operations] 142 142 143 143 === Added support for Dataset.!BuildOverviews (#1552) === 144 144 145 The 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 {{{ 148 public int BuildOverviews( string resampling, int[] overviewlist) 149 }}} 150 151 The [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 {{{ 154 gdaloverviews {GDAL dataset name} {resamplealg} {level1} {level2} .... 155 }}} 156 157 The 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 {{{ 160 gdalread {GDAL dataset name} {output file name} {overview_level} 161 }}} 162 163 145 164 === Examples added === 165 166 Along 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.
