The following code shows how to display the vector image export dialog, that allows the user to pick the vector image export format:

NChartVectorImageExporter imageExporter = new NChartVectorImageExporter(chartView.Content);
imageExporter.ShowDialog(DisplayWindow, true);

The following code shows a save image file dialog that allows the user to create a vector image from the chart:

NChartVectorImageExporter imageExporter = new NChartVectorImageExporter(chartView.Content);
imageExporter.SaveAsImage(ENVectorImageFormat.Svg); // Save to image with SVG file format selected by default

To export the chart to a vector image and save it directly to a file, without showing a save file dialog, you can use the SaveToFile method. Note that the saving to a file is an asynchronous (async) operation, so if you are interested in its completion, you should call the Then method of the promise it returns and handle the completion of the export in the passed delegate. The following is a code example:

NChartVectorImageExporter imageExporter = new NChartVectorImageExporter(chartView.Content);
imageExporter.SaveToFileAsync("C:\\ExportedImage.svg").Then(
    delegate (NUndefined ud)
    {
        // Export to SVG completed
    }
);

To export a chart to a vector image stream, you can use the SaveToStream method. Unlike the SaveToFile method, the SaveToStream method runs synchronously and blocks code execution until it completes. Exporting charts to a stream is useful when you wish to generate images in memory instead of saving them to the disc. The following code snippet shows how to export a chart to a stream:

NChartVectorImageExporter imageExporter = new NChartVectorImageExporter(chartView.Content);
imageExporter.SaveToStream(stream, ENVectorImageFormat.Svg);

To generate an SVG document on the fly without saving it, you should use the CreateSvg method:

NChartVectorImageExporter imageExporter = new NChartVectorImageExporter(chartView.Content);
NSvgDocument svgDocument = imageExporter.CreateSvg();

You can use the CreateEmf and CreateDxf methods to create EMF byte arrays and DXF documents, respectively.

To copy the vector image to the clipboard, you should use the CopyToClipboard method:

NChartVectorImageExporter imageExporter = new NChartVectorImageExporter(chartView.Content);
imageExporter.CopyToClipboard(ENVectorImageFormat.Svg);

The CopyToClipboard method in the case of EMF, places it in the clipboard and for SVG and AutoCAD DXF places their source code in the clipboard.
