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.

You may be also be interested in the iOS/Swift version of the library.

}
  dependencies {

  compile 'io.uuddlrlrba:close-pixelate:1.2.0' 
}

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
	+		=

json-parser-generator

Project is inspired by ig-json-parser. It basically do the same thing as ig-json-parser, but the differences are:

do not use annotations to generate the parsers. but use Scala raw value
including a class JsonToSpec which can generate the spec from a folder of json samples. so you not even need to write the spec if you have a working backend. but most of time you will want to customize the result by editing the result spec
you can write converter code to convert between types
it is dead simple
