Dispose(bool) Method

Summary

Releases all the resources used by this RasterImage.

Syntax

C++/CLI

Python

[HandleProcessCorruptedStateExceptionsAttribute()] 
protected virtual void Dispose( 
   bool disposing 
)

protected: 
virtual void Dispose(  
   bool disposing 
)

def Dispose(self,disposing):

Parameters

disposing
True to release both managed and unmanaged resources; False to release only unmanaged resources.

Remarks

The RasterImage class implements the IDisposable interface, it is recommended that you follow the standard .NET dispose pattern when using the RasterImage class. For more information, refer to the IDisposable interface documentation in MSDN, the IsDisposed property and the RasterImage.Disposed event.
