MapItemsLayerBase.ExportToSvg(String, Double, SvgExportOptions) Method

Exports data from this vector layer to the specified SVG file using the defined parameters.

Namespace: DevExpress.XtraMap

Assembly: DevExpress.XtraMap.v23.2.dll

NuGet Package: DevExpress.Win.Map

Declaration

C#

public void ExportToSvg(
    string filePath,
    double scale,
    SvgExportOptions exportOptions
)

VB.NET

Public Sub ExportToSvg(
    filePath As String,
    scale As Double,
    exportOptions As SvgExportOptions
)

Parameters

Name	Type	Description
filePath	String	The path of the file that is used to save vector items.
scale	Double	The scale factor used to export map items to SVG.
exportOptions	SvgExportOptions	The storage of values required for correct export.

Remarks

The export method requires several property values of the MapControl. If the layer is not added to the MapControl, the exportOptions parameter provides these values.

Note

Note that if this method is used, the parameters of exportOptions are always used instead of parameters of the Map Control.

Example

This example shows how to export the map vector layer items to the .SVG, .KML, and .SHP file formats.

The following API members are used:

Member	Description
MapItemsLayerBase.ExportToSvg	Exports data from this vector layer to the specified stream using the defined parameters.
SvgExportOptions	The options to be applied when exporting the vector layer to the SVG file format.
MapItemsLayerBase.ExportToKml	Exports data from this vector layer to the specified stream using the KML file format.
MapItemsLayerBase.ExportToShp	Exports this vector layer data to the specified shapefile.
ShpExportOptions	The options to be applied when exporting the vector layer to a shapefile.
XtraSaveFileDialog	A dialog that allows a user to save a file. Supports DevExpress Skins.
