Java PngEncoder - worlds fastest java png encoder

ObjectPlanet's PngEncoder lets you encode java based image objects into various PNG images at fantastic performance compared to other png encoders. This PngEncoder is the fastest java based png encoder we know of and has a very small footprint of just a few kilobytes.

The encoder is free of charge, while the source code is available for a fee.

You encode your java images to an output stream with one line of code
(new PngEncoder()).encode(image, outputstream);

Unmatched performance
