-
Searches the provided list of layers for any visible vector features within the provided search distance (aMaxDistPixels) of the pixel search location (aPixelSearchPt). The aFindFlags parameter specifies what types of features to search on.
- Parameters:
-
aPixelSearchPt (GM_Point_t) – Search location in pixel coordinates
aLayerList ([GM_LayerHandle_t32]) – List of layers to search or None for all vector layers
aFindFlags (GM_FindFlags_t32) – Flags controlling how the find is performed
aWorldBounds (GM_Rectangle_t) – World bounds for search space or None for last drawn
aPixelRect (GM_PixelRect_t) – Pixel bounds for search space or None for last drawn
MAX_OUTPUT_LEN (uint32) – Max number of nearest features to find
aMaxDistPixels (uint32) – Max distance in pixels to search
