The PNG format is a format for lossless raster images, which is able to replace such classic formats as TIFF and GIF. It was designed to work mainly with WWW applications; it is robust and provides integrity checks for the file. It was designed for the purpose of replacing the GIF format, but it also has additional design properties that were added with small effort from the designers. The features that are implemented in PNG and are absent in GIF format include:  Support for images with up to 48 bits per pixel, in True Color.

Introduction This document proposes an image format for storing full-color image values in 16-bit pixels. The data representation itself need not be in a PNG (Portable Network Graphics) envelope, but PNG does provide a natural and widely accepted framework for this proposal. PNG is now one of the three image formats supported by the major browsers (Netscape and Internet Explorer), and Microsoft has even declared it to be its primary lossless image format within the Office 98 software suite. Why 16 bits? Well, 8 bits per pixel is inadequate for

# Introduction The png-16 image format stores imagery in 16-bit pixels. It is being developed to offer several unique benefits: * losslessly compressed true-color imagery in smaller files then 24-bit color * provide a display space for color imagery indistinguishable from 24-bit color * provide an analytical and display space for grey imagery up to 12 bits per pixel * allow deep grey and true color to co-exist in less than 48 bits per pixel * add extra image features such as: o positive and negative transparency o extremely flexible color

The PNG format provides a portable, legally unencumbered, well-compressed, well-specified standard for lossless bitmapped image files. Although the initial motivation for developing PNG was to replace GIF, the design provides some useful new features not available in GIF, with minimal cost to developers. GIF features retained in PNG include: * Indexed-color images of up to 256 colors. * Streamability: files can be read and written serially, thus allowing the file format to be used as a communications protocol for on-the-fly generation and
