Exports layer.
Syntax
// C# public void ExportLayer( TGIS_LayerVector _layer, TGIS_Extent _extent, TGIS_ShapeType _type, string _scope, TGIS_Shape _shape, string _de9im, bool _truncated );
' VisualBasic Public Sub ExportLayer( ByVal _layer As TGIS_LayerVector, ByVal _extent As TGIS_Extent, ByVal _type As TGIS_ShapeType, ByVal _scope As String, ByVal _shape As TGIS_Shape, ByVal _de9im As String, ByVal _truncated As Boolean )
// Oxygene public procedure ExportLayer( _layer : TGIS_LayerVector; _extent : TGIS_Extent; _type : TGIS_ShapeType; _scope : String; _shape : TGIS_Shape; _de9im : String; _truncated : Boolean );
Parameters
| Name | Type | Description |
|---|---|---|
| _layer | TGIS_LayerVector | layer to be exported to |
| _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 export will try to recognize shape on its own; |
| _scope | string String | SQL query for which shape will be exported |
| _shape | TGIS_Shape | if not nil, then only shapes matched _de9im matrix with _shape will be found |
| _de9im | string String | DE-9IM matrix of comparison |
| _truncated | bool Boolean | if True, then all shapes will be truncated in _extent; if False, only the shape visible in _extent will be exported ; |
Remarks
Remember to assign 'path' property to the layer you want to export to, for proper export of the new layer to a file.
Use this method to export a layer. To do this, choose a layer to export to, and use ExportLayer method with proper params. See also the opposite method, ImportLayer.
Example
Here is a simple procedure to export a layer.
