This application is built for Android software engineers, but anyone can have fun with it!

Features
• Live preview
• Pick any image you want
• ...even transparent animated GIFs
• Smooth color picker
• Different color swatches
• Built-in custom keyboards
• Generate code
• Share preview with code
• Full state auto-save

Purpose
The documentation of the classes extending android.graphics.ColorFilter is pretty thin, and creating filters based on these to achieve the wanted effects may not be trivial. This application lets you try all the possible parameter combinations with a live preview of your chosen image.

Supported Classes
Currently (API Level 22 / M 5.1) all built-in color filters in the android.graphics package and the support library's palette classes are supported.
• Palette/Swatch
• ColorMatrixColorFilter
• LightingColorFilter
• PorterDuffColorFilter
For more information see:
http://developer.android.com/reference/android/graphics/ColorFilter.html

Permissions
Read external storage to load images for preview
Write external storage for capturing images from the camera and sharing previews
