GOALS: Complete PNG encoding and decoding for Unity engine

Simple API to read and write Texture2D objects, raw data
Drop "Pngcs" folder in your project, no other dependencies, just works.

API:

Texture2D PNG.Read
Texture2D PNG.ReadAsync (experimental)
Color[] PNG.ReadColors
Color[] PNG.ReadColorsAsync (experimental)
PNG.Write
PNG.WriteAsync (experimental)
PNG.WriteLargeAsync (experimental)
PNG.WriteGrayscaleAsync (experimental)

TODO:

PNG.Read creating Texture2D in every useful TextureFormat, infered from file (partially done already)
Improve READ/WRITE speeds
PNG.Read/Write byte[]
PNG.Read with target width and height arguments (to preview bigger image etc.)
PNG.Read with image rect argument (read texture atlas region)

HOW TO USE:

using UnityEngine;
using Pngcs.Unity;
public class PngcsTest : MonoBehaviour
{
    void Awake ()
    {
        // THIS IS HOW YOU READ:
        Texture2D texture = PNG.Read( @"D:/input.png" );

        // THIS IS HOW YOU WRITE:
        PNG.Write( texture , @"D:/output.png" );
    }
    
    void OnDestroy ()
    {
        //remember to always release memory when texture is not needed anymore:
        Destroy( texture );
    }
}

REQUIREMENTS:

Unity 2017.1
Scripting runtime version: C# 4.x

This window is available under top menu bar/Test/Pngcs Load Note: Alpha8 images appear inverted here but aren't - it's due to no color info but black fill and transparency.
