filter - "Gray.js" or "BlurX.js" how to configure filter?

[valueerror]

hello fellow phaser lovers..  i'm just giving filters a shot and i need to "gray-out" some elements ..  

the first task was very easy thx to the examples on examples.phaser.io but now i wonder if it is possible to configure those filters 

 

for example it would be nice to desaturate my images but not completely..  unfortunately i can't make any sense out of the code inside gray.js

also setting the grade of the blur would be nice.. it is definitely to muche blurred right now..

 

thx in advance for any tips on how to accomplish this

well..  i figured it out  

 

for anyone who wants to add a gray filter (desaturate) to his game... here is the how to..

 

preload:  (get gray.js from phaser git repo)

game.load.script('gray', 'Gray.js');

create:

grayfilter = game.add.filter('Gray');grayfilter.gray = 0.6;  // this sets the amount of de-saturation (1 is full)stageGroup.filters = [gray]; // apply filter to something

the only question that remains is why do i need to import gray.js - why can't i just do something like:

 

grayfilter = new PIXI.GrayFilter();

you have to know.. i am able to use other things from here http://docs.phaser.io/PIXI.html  like new PIXI.RenderTexture or new PIXI.Matrix  so i am a little bit (or very much) confused
