Remarks

The SvgDocument class represents a Scalable Vector Graphics (SVG) object. LEADTOOLS supports versions 1.* to 2.0 of the SVG specification.

The SvgDocument class implements System.Runtime.Serialization.ISerializable and fully supports .NET serialization.

The SvgDocument class implements System.IDisposable. You must use the .NET dispose pattern or call Dispose on the object after using it.

The SvgDocument class implements Leadtools.ISvgDocument and can be cast directly from the other LEADTOOLS methods that return an instance of that interface.

For more information about using SvgDocument, refer to Working With SVG.

Example

This example will try to load the first page of each document in a folder as SVG. If successful, it will save the page as an SVG file.
