[gdal-dev] Using GDALTranslateOptions with '-a_ullr' doesn't work

[Paul Meems]

Thanks Even for your reply, it helped me great.

For future reference here's the working C# code:

var options =
    new GDALTranslateOptions(new[]
    {
        "-of", "GTiff",
        "-a_nodata", "65535",
        "-a_srs", "+proj=stere +lat_0=90 +lon_0=0 +lat_ts=60 +a=6378.14
+b=6356.75 +x_0=0 y_0=0",
        "-a_ullr", "0.0", "-3650.000", "800.000", "-4415.000"
    });
var newDs = Gdal.wrapper_GDALTranslate(outputFile, ds, options, null, null);

Paul
