README - Sixlegs Java PNG Decoder

Features

Supports all valid bit depths (grayscale/color), interlacing, paletted images, alpha channel/transparency, gamma correction, access to all standard chunks, private chunk handling, and progressive display.

Getting Started

After including the javapng jar file in your classpath, typical usage is as follows:

create a new instance of PngImage

com.sixlegs.png.PngImage png = new com.sixlegs.png.PngImage();

decode a PNG file into a BufferedImage using the read method

java.awt.image.BufferedImage image =
png.read(new java.io.File("test.png"));

the PngImage object will now provide access to the metadata

int colorType = png.getColorType();
