android-close-pixelate

This simple library allows you to easily create and combine various pixelation effects.
Based on a wonderful script by David DeSandro: close-pixelate.desandro.com.

Usage
There are several Pixelate.from*
methods in the Pixelate
class, allowing to create a pixelated bitmap from other bitmaps, resources, input streams, etc:
Bitmap pixelated = new Pixelate.fromBitmap(
bitmap,
new PixelateLayer.Builder(PixelateLayer.Shape.Square)
.setResolution(48)
.setSize(50)
.build() );
You also can draw directly on a bitmap or on a canvas, using Pixelate.render*
methods.
There are three basic layer types:
Original | Square | Diamond | Circle |
 |  |  |  |
You can change size, resolution, offset and alpha parameters of each layer:
resolution = 10 | resolution = 25 | resolution = 20, size = 50, alpha = 0.5 |
 |  |  |
You can also combine several layers into one image:
square, resolution = 25 | | diamond, resolution = 10 | | |
 | + |  | = |  |
