divisor (ConvolutionFilter.divisor property)

The divisor used during matrix transformation. The default value is 1. A divisor that is the sum of all the matrix values evens out the overall color intensity of the result. A value of 0 is ignored and the default is used instead.

import flash.filters.ConvolutionFilter;
import flash.display.BitmapData;
    
var filter:ConvolutionFilter = new ConvolutionFilter(3, 3, [1, 1, 1, 1, 1, 1, 1, 1, 1], 9);

var myBitmapData:BitmapData = new BitmapData(100, 80, false, 0x00FF0000);

var mc:MovieClip = this.createEmptyMovieClip("mc", this.getNextHighestDepth());
mc.attachBitmap(myBitmapData, this.getNextHighestDepth());
myBitmapData.noise(128);
        
mc.onPress = function() {
    var newDivisor:Number = 6;
    filter.divisor = newDivisor;
        myBitmapData.applyFilter(myBitmapData, myBitmapData.rectangle, new Point(0, 0), filter);
