Locates a shape.
Syntax
# Python def Locate( self, _ptg: TGIS_Point, _prec: float ) -> TGIS_Shape:
Parameters
| Name | Type | Description |
|---|---|---|
| _ptg | TGIS_Point | reference point /searching point/; if the layer has been attached to the Viewer then expected _ptg units are in a Viewer coordinate space; otherwise expected _ptg units are in a Layer coordinate space |
| _prec | float | 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 _prec units are calculated same way as _ptg |
Result
| Type | Description |
|---|---|
| TGIS_Shape | Found shape or nil. |
Remarks
Use this method to locate a shape that is closest to point _ptg but also on _prec distance. Internally it calls LocateEx method.
