Syntax
C#
Objective-C
C++/CLI
Java
Python
public void StopDithering() 
- (BOOL)stopDithering:(NSError **)error 
public void stopDithering();

Remarks

This method resets all internal variables to their default settings. For a description of how the methods relate to each other, refer to StartDithering method.

This method does not support signed images.
