问题
i want to blur particular area on image view.
eg. i want to allow user to draw rectangle similar to crop in android, once user draws that rectangle on image, the area inside rectangle will be blurred or on finger touch.
i searched a lot,but most of the examples explain how to blur full image, dint find any tutorial or link that explains about blurring only some part of an image.
any help will be really appreciated.

There's nothing easier!
But you can only pixelate it, select the targeted area, press (Ctrl+-) twice or thrice, then (Ctrl++) the same number of times.
