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
	+		=
