Methods
| Name | Visibility | Description | |
|---|---|---|---|
| GisExpandLabel(String; TGIS_ExpandLabelFun) | public | Expands label text by resolving embedded field placeholders through a custom callback method. | |
| GisExpandLabel(String; TGIS_Shape) | public | Expands label text by replacing embedded field placeholders with values read from a shape's attribute fields. | |
| GisIsPointInsidePolygon(TGIS_Point; TGIS_ShapePolygon) | public | Determines whether a point lies inside or on the boundary of a polygon shape, including multipart polygons and polygons with holes. | |
| GisIsPointInsidePolygon(TGIS_Point; TGIS_ShapePolygon; Integer) | public | Determines if point lies inside a polygon with optional per-part control. | |
