Locate a shape that is near _pt, but is closer than _prec distance.
Implements IGIS_Viewer.Locate.
// C# public TGIS_ShapeAbstract Locate( TPoint _pt, int _prec );
' VisualBasic Public Function Locate( ByVal _pt As TPoint, ByVal _prec As Integer ) As TGIS_ShapeAbstract
// Oxygene public function Locate( _pt : TPoint; _prec : Integer ) : TGIS_ShapeAbstract;
Name | Type | Description |
---|---|---|
_pt | TPoint | reference point /searching point/ in pixels |
_prec | int Integer | 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 pixels |
Type | Description |
---|---|
TGIS_ShapeAbstract | Located shape or nil |
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.
