Function Documentation
PLAYERC_EXPORT void playerc_vectormap_cleanup | ( | playerc_vectormap_t * | device | ) |
Clean up the dynamically allocated memory for the vectormap.
PLAYERC_EXPORT playerc_vectormap_t* playerc_vectormap_create | ( | playerc_client_t * | client, |
int | index | ||
) |
Create a vectormap proxy.
PLAYERC_EXPORT void playerc_vectormap_destroy | ( | playerc_vectormap_t * | device | ) |
Destroy a vectormap proxy.
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_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.
PLAYERC_EXPORT int playerc_vectormap_get_map_info | ( | playerc_vectormap_t * | device | ) |
Get the vectormap metadata, which is stored in the proxy.
PLAYERC_EXPORT int playerc_vectormap_subscribe | ( | playerc_vectormap_t * | device, |
int | access | ||
) |
Subscribe to the vectormap device.
PLAYERC_EXPORT int playerc_vectormap_unsubscribe | ( | playerc_vectormap_t * | device | ) |
Un-subscribe from the vectormap device.
PLAYERC_EXPORT int playerc_vectormap_write_layer | ( | playerc_vectormap_t * | device, |
const player_vectormap_layer_data_t * | data | ||
) |
Write layer data.
