TGIS_Shape.TGIS_Shape(TGIS_Shape, TGIS_Bytes, bool, long, TGIS_LayerVector) constructor
DK for .NET | TatukGIS.NDK.TGIS_Shape.Create | Overloads | Constructors | Fields | Methods | Properties
Create a 2D shape instance from an existing shape or from raw internal geometry data.
Available also on: Java.
Syntax
// C# public TGIS_Shape( TGIS_Shape _source, TGIS_Bytes _ptr, bool _mapped, long _uid, TGIS_LayerVector _layer );
' VisualBasic Public Sub New( ByVal _source As TGIS_Shape, ByVal _ptr As TGIS_Bytes, ByVal _mapped As Boolean, ByVal _uid As Long, ByVal _layer As TGIS_LayerVector )
// Oxygene public constructor ( _source : TGIS_Shape; _ptr : TGIS_Bytes; _mapped : Boolean; _uid : TGIS_Uid; _layer : TGIS_LayerVector );
Parameters
| Name | Type | Description |
|---|---|---|
| _source | TGIS_Shape | Source shape to clone or use as a template. If assigned, _ptr, _mapped, _uid, and _layer are ignored. |
| _ptr | TGIS_Bytes | Pointer or platform-specific buffer containing internal shape geometry data. |
| _mapped | bool Boolean | True if _ptr references memory-mapped data; False if it references regular in-memory data. |
| _uid | long TGIS_Uid | Unique identifier assigned to the shape. |
| _layer | TGIS_LayerVector | Vector layer that owns or provides context for the shape. |
Remarks
TGIS_LayerVector.CreateShape is recommended instead.PURPOSE: Create a 2D shape using an existing shape template or internal geometry storage supplied by the vector-layer framework.
BEHAVIOR: Initializes the shape and delegates setup toRecreate. The constructor can either clone from _source or bind the shape to raw geometry data, UID, and layer context.
CONSTRAINTS: Intended mainly for internal or advanced use. When _ptr is used, the caller is responsible for providing valid data compatible with the shape implementation.
Example
This is a simple procedure showing how to add a shape to the layer.
