AddFromSvgDocument Method

Summary

Adds a new item from an SvgDocument object.

Syntax

C++

public ImageViewerItem AddFromSvgDocument( 
   SvgDocument document 
)

Public Function AddFromSvgDocument( 
   ByVal document As SvgDocument 
) As ImageViewerItem

public:  
   ImageViewerItem^ AddFromSvgDocument( 
      SvgDocument^ document 
   )

Parameters

document

Source SVG document.

Return Value

The newly created item if successful.

Remarks

Use AddFromImage to add an item from a RasterImage object.

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

ImageViewerItem item = new ImageViewerItem(); 
item.SvgDocument = document; 
imageViewer.Items.Add(item);

If document is null, then an empty item is added.

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