示例1: createTileGeom
import com.vividsolutions.jts.geom.GeometryFactory; //導入方法依賴的package包/類
/**
* <p>Create geometry clipped and then converted to MVT 'extent' coordinates. Result
* contains both clipped geometry (intersection) and transformed geometry for encoding to
* MVT.</p>
* <p>Allows specifying separate tile and clipping coordinates. {@code clipEnvelope} can be bigger
* than {@code tileEnvelope} to have geometry exist outside the MVT tile extent.</p>
*
* @param geometryList original 'source' geometry, passed through
* {@link #flatFeatureList(Geometry)}
* @param tileEnvelope world coordinate bounds for tile, used for transforms
* @param clipEnvelope world coordinates to clip tile by
* @param geomFactory creates a geometry for the tile envelope
* @param mvtLayerParams specifies vector tile properties
* @param filter geometry values that fail filter after transforms are removed
* @return tile geometry result
* @see TileGeomResult
