ITGIS_Shape.Combine_2 method
DK for ActiveX | TatukGIS_XDK11.ITGIS_Shape.Combine_2 | Methods | Properties
Performs a boolean geometry operation between this shape and another shape, optionally returning a new object or modifying this shape.
Syntax
// C# public ITGIS_Shape Combine_2( ITGIS_Shape _shape, TGIS_TopologyCombineType _operation, WordBool _returnnewobj );
' VisualBasic Public Function Combine_2( ByVal _shape As ITGIS_Shape, ByVal _operation As TGIS_TopologyCombineType, ByVal _returnnewobj As WordBool ) As ITGIS_Shape
// Oxygene public function Combine_2( _shape : ITGIS_Shape; _operation : TGIS_TopologyCombineType; _returnnewobj : WordBool ) : ITGIS_Shape;
Parameters
| Name | Type | Description |
|---|---|---|
| _shape | ITGIS_Shape | Shape to combine with. Must have valid geometry. |
| _operation | TGIS_TopologyCombineType | Operation type from TGIS_TopologyCombineType. |
| _returnnewobj | WordBool | If True, returns a newly created result shape. If False, updates this shape and returns the same instance. |
Result
| Type | Description |
|---|---|
| ITGIS_Shape | The operation result as either a new shape or this modified shape, depending on _returnnewobj. |
Remarks
PURPOSE: Execute a topology operation with control over result ownership and in-place modification behavior.
BEHAVIOR: Applies the operation specified by _operation. If _returnnewobj is True, a new result shape is created. If False, this shape is replaced by the result and returned.
CONSTRAINTS: When _returnnewobj is False, the original geometry of this shape is overwritten. Ownership of the return value follows the annotation on the declaration.
