Function Documentation
| GEOSGeom playerc_vectormap_get_feature_data | ( | playerc_vectormap_t * | device, | |
| unsigned | layer_index, | |||
| unsigned | feature_index | |||
| ) |
Get an individual feature as a geos geometry.
Must only be used after a successful call to playerc_vectormap_get_layer_data. The geos geometry is owned by the proxy, duplicate it if it is needed after the next call to get_feature_data. Non-reentrant.
| int playerc_vectormap_get_layer_data | ( | playerc_vectormap_t * | device, | |
| unsigned | layer_index | |||
| ) |
Get the layer data by index.
Must only be used after a successfull call to playerc_vectormap_get_map_info.
