Full support of PNG is required for conforming SVG viewers at the time of publication all eighteen SVG viewers had PNG support. At the time of this publication more than 180 image viewers could display PNG images and over 100 image editors could read and write valid PNG files. The PNG specification enjoys a good level of implementation with good interoperability. A major design goal during this review was to avoid changes that will invalidate existing files, editors, or viewers that conform to W3C Recommendation PNG Specification Version 1.0. This second edition incorporates all known errata and clarifications.Ī complete review of the document has been done by ISO/IEC/JTC 1/SC 24 in collaboration with W3C and the PNG development group (the original authors of the PNG 1.0 Recommendation) in order to transform that Recommendation into an ISO/IEC international standard. This International Standard is strongly based on the W3C Recommendation 'PNG Specification Version 1.0' which was reviewed by W3C members, approved as a W3C Recommendation and published in October 1996. The two documents have exactly identical content except for cover page and boilerplate differences as appropriate to the two organisations. It is also International Standard, ISO/IEC 15948:2003. Recommendation of the PNG specification, second edition.

This section describes the status of this document at the time of its publication. This specification defines an Internet Media Type image/png. Also, PNG can store gamma and chromaticity data for improved color matching on heterogeneous platforms. PNG is robust, providing both full file integrity checking and simple detection of common transmission errors. PNG is designed to work well in online viewing applications, such as the World Wide Web, so it is fully streamable with a progressive display option. Indexed-color, grayscale, and truecolor images are supported, plus an optional alpha channel. PNG provides a patent-free replacement for GIF and can also replace many common uses of TIFF. This document describes PNG (Portable Network Graphics), an extensible file format for the lossless, portable, well-compressed storage of raster images. W3C liability, trademark, document use and software licensing rules apply. See also the translations of this document.Ĭopyright © 2003 W3C ® ( MIT, ERCIM, Keio), All Rights Reserved.
