TwoParameterFilter

All Implemented Interfaces:

com.otaliastudios.cameraview.filter.Filter , com.otaliastudios.cameraview.filter.OneParameterFilter
```
public interface TwoParameterFilter
 implements OneParameterFilter
                    
```
A special Filter that accepts two floats parameters. This is done by extending OneParameterFilter. The parameters will always be between 0F and 1F, so subclasses should map this range to their internal range if needed. A standardized range is useful for different applications. For example: - Filter parameters can be easily mapped to gestures since the range is fixed - BaseFilter can use this setters and getters to make a filter copy
