Remarks

This method will load the data as a SVG document using ImageViewer.RasterCodecsInstance.LoadSvg. To load the data as a raster image, use AddFromImageFile.

This method allows you to quickly add an item from a disk file. It is the equivalent of the following code:

ImageViewerItem item = new ImageViewerItem(); 
item.SvgDocument = imageViewer.RasterCodecsInstance.LoadSvg(fileName, pageNumber, null); 
imageViewer.Items.Add(item);

The value of AutoRenderOptimizeSvgDocuments will determine if the viewer should optimize the SVG document for rendering.
