Function Documentation

◆ playerc_vectormap_get_feature_data()

PLAYERC_EXPORT uint8_t * playerc_vectormap_get_feature_data ( playerc_vectormap_t * device,
unsigned layer_index,
unsigned feature_index )

Get an individual feature as a WKB geometry.

Must only be used after a successful call to playerc_vectormap_get_layer_data. The WKB geometry is owned by the proxy, duplicate it if it is needed after the next call to get_feature_data.

◆ playerc_vectormap_get_layer_data()

PLAYERC_EXPORT 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.
