Crop face area

[helio]

I create application where user upload photo from local computer, and then scaling and rotating photo using slider. I use TransformManager. I want crop only face when user click on button. Here screenshot similar application

 

After click next button image cropping.

 

But I don't know how to crop image without double clicking on image and then choose area. I disable scale and rotation handle and using only slider.  For example. I have image inside sprite. Image have size 2000x2000. After change scaleX and scaleY using slider, image size have 800x800. My crop area 330x354. How to crop image using this crop area. And how to update image size in crop.update() method then I change image size. Here full http://pastebin.com/ZZJ9RhH7.

You should be able to accomplish almost anything directly through code (rather than relying on user interaction). For example the "Crop" class has a "cropMode" property that you can set to true or false. Setting it to true should kick it into cropping mode, and you can move/scale it as you please.
