Summary

Releases all resources used by this SvgDocument.

Syntax

C++/CLI

Java

Python

public void Dispose()

public synchronized void dispose()

public: 
void Dispose();

def Dispose(self):

Remarks

The SvgDocument class implements the System.IDisposable interface. It is best to follow the standard .NET dispose pattern when using the SvgDocument class. For more information, refer to the System.IDisposable interface documentation in MSDN.
