Thresholdfilter. Colors lighter than the selectable threshold are converted to white darker colors will be black. For events of level equal or above the threshold thresholdfilter will respond neutral when its decide method is invoked.
Replace all negatively signed measurements with a value of zero. Thresholdfilter this filter returns the onmatch result if the level in the logevent is the same or more specific than the configured level and the onmismatch value otherwise. Threshold filters are commonly used in digital signal processing.
However events with a level below the threshold will be denied.
For events of level equal or above the threshold thresholdfilter will respond neutral when its decide method is invoked. The thresholdfilter filters events below the specified threshold. Threshold effect black and white generator. Reduces the photo to black and white.
