Reproject image.<p>
This is a convenience function utilizing the <a class="el" href="classGDALWarpOperation.html">GDALWarpOperation</a> class to reproject an image from a source to a destination. In particular, this function takes care of establishing the transformation function to implement the reprojection, and will default a variety of other warp options.<p>
By default all bands are transferred, with no masking or nodata values in effect. No metadata, projection info, or color tables are transferred to the output file.<p>
