Member Function Documentation

osg::Image* CustomTileSource::createImage	(	const TileKey &	key,
		ProgressCallback *	progress
	)		[inline, virtual]

Creates an image for the given TileKey. The returned object is new and is the responsibility of the caller.

Implements osgEarth::TileSource.

Definition at line 66 of file osgearth_tilesource.cpp.

    {
        GeometryRasterizer rasterizer( 256, 256 );
        rasterizer.draw( _geom.get(), colors[key.getLevelOfDetail() % 4] );
        return rasterizer.finalize();
    }

Here is the call graph for this function:

void CustomTileSource::initialize	(	const std::string &	referenceURI,
		const Profile *	overrideProfile
	)		[inline, virtual]

Initialize the TileSource. The profile should be computed and set here using setProfile()

Implements osgEarth::TileSource.

Definition at line 58 of file osgearth_tilesource.cpp.

    {
        if ( overrideProfile )
            setProfile( overrideProfile );
        else
            setProfile( Registry::instance()->getGlobalGeodeticProfile() );
