DK11 for .NET | TatukGIS.NDK.TGIS_LayerVector.ImportLayer | Overloads | Constructors | Fields | Methods | Properties | Events
Imports a layer from an existing layer.
Syntax
// C# public void ImportLayer( TGIS_LayerVector _layer, TGIS_Extent _extent, TGIS_ShapeType _type, string _scope, bool _truncated );
' VisualBasic Public Sub ImportLayer( ByVal _layer As TGIS_LayerVector, ByVal _extent As TGIS_Extent, ByVal _type As TGIS_ShapeType, ByVal _scope As String, ByVal _truncated As Boolean )
// Oxygene public procedure ImportLayer( _layer : TGIS_LayerVector; _extent : TGIS_Extent; _type : TGIS_ShapeType; _scope : String; _truncated : Boolean );
Parameters
| Name | Type | Description |
|---|---|---|
| _layer | TGIS_LayerVector | layer to be imported |
| _extent | TGIS_Extent | starting extent of layer - can't be zero sized |
| _type | TGIS_ShapeType | shape type supported by a layer; if gistypeUnknown is used then import will try to recognize shape on its own; |
| _scope | string String | SQL query for which shape will be imported |
| _truncated | bool Boolean | if True, then all shapes will be truncated in _extent; if False, only the shape visible in _extent will be imported ; |
Remarks
Remember to assign 'path' property to the layer you want to import from, for proper import of the new layer to a file.
Use this method to import a layer. To do this, simply create a new layer, choose a layer to import from and use ImportLayer method with proper params. See also the opposite method, ExportLayer.
