Locate a shape that is near _ptg, but is closer than _prec distance.
// Java public TGIS_ShapeAbstract Locate( TGIS_Point _ptg, double _prec, bool _visible );
// Oxygene public function Locate( _ptg : TGIS_Point; _prec : Double; _visible : Boolean ) : TGIS_ShapeAbstract;
Name | Type | Description |
---|---|---|
_ptg | TGIS_Point | reference point /searching point/ |
_prec | double Double | precision /not a longer distance than/; for points inside the polygon (if _prec >= 0) the distance will be multiply by 0.95 (to prefer points inside the polygon) but will not be bigger then _prec; for point distance will be multiplied by 0.9 to prefer points over lines and polygons; precision is express in map units |
_visible | bool Boolean | if true the only visible shapes will be evaluated; shapes turned of by query of hidden will be ignored |
Type | Description |
---|---|
TGIS_ShapeAbstract | Located shape or nil |
To improve performance sections visibility can be used to choose layer to call its Locate method. Only visible shapes will be evaluated.
If no shape is found on a layer, the searcher takes into account labels registered by the allocator (by extent). In order to disable this behavior, _visible must be set to False.
