C++ ProfileOptions::getConfig方法代码示例

Profile::Profile(const SpatialReference* srs,
                 double xmin, double ymin, double xmax, double ymax,
                 double geo_xmin, double geo_ymin, double geo_xmax, double geo_ymax,
                 unsigned int numTilesWideAtLod0,
                 unsigned int numTilesHighAtLod0 ) :

osg::Referenced( true )
{
    _extent = GeoExtent( srs, xmin, ymin, xmax, ymax );

    _numTilesWideAtLod0 = numTilesWideAtLod0 != 0? numTilesWideAtLod0 : srs->isGeographic()? 2 : 1;
    _numTilesHighAtLod0 = numTilesHighAtLod0 != 0? numTilesHighAtLod0 : 1;

    _latlong_extent = GeoExtent( 
        srs->getGeographicSRS(),
        geo_xmin, geo_ymin, geo_xmax, geo_ymax );

    //if ( !_vsrs.valid() )
    //    _vsrs = Registry::instance()->getDefaultVSRS();

    // make a profile sig (sans srs) and an srs sig for quick comparisons.
    ProfileOptions temp = toProfileOptions();
    _fullSignature = Stringify() << std::hex << hashString( temp.getConfig().toJSON() );
    temp.vsrsString() = "";
    _horizSignature = Stringify() << std::hex << hashString( temp.getConfig().toJSON() );
}

/**
 * Command-line tool that copies the contents of one TileSource
 * to another. All arguments are Config name/value pairs, so you need
 * to look in the header file for each driver's Options structure for
 * options :)
 *
 * Example: copy a GDAL file to an MBTiles repo:
 *
 *   osgearth_conv
 *      --in driver gdal
 *      --in url world.tif
 *      --out driver mbtiles
 *      --out filename world.db
 *
 * The "in" properties come from the GDALOptions getConfig method. The
 * "out" properties come from the MBTilesOptions getConfig method.
 *
 * Other arguments:
 *
 *      --elevation           : convert as elevation data (instead of image data)
 *      --profile [profile]   : reproject to the target profile, e.g. "wgs84"
 *      --min-level [int]     : min level of detail to copy
 *      --max-level [int]     : max level of detail to copy
 *      --threads [n]         : threads to use (may crash. Careful.)
 *
 *      --extents [minLat] [minLong] [maxLat] [maxLong] : Lat/Long extends to copy (*)
 *
 * Of course, the output driver must support writing (by implementing
 * the ReadWriteTileSource interface).
