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.v24.1.dll

NuGet Package: DevExpress.Win.Map

Declaration

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

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.
