C members, approved as a W3.C Recommendation and published in October 1.This second edition incorporates all known errata and clarifications.A complete review of the document has been done by ISOIECJTC 1SC 2.W3. C and the PNG development group the original authors of the PNG 1.Recommendation in order to transform that Recommendation into an ISOIEC international standard.A major design goal during this review was to avoid changes that will invalidate existing files, editors, or viewers that conform to W3.C Recommendation PNG Specification Version 1.The PNG specification enjoys a good level of implementation with good interoperability.At the time of this publication more than 1.PNG images and over 1.PNG files. Full support of PNG is required for conforming SVG viewers at the time of publication all eighteen SVG viewers had PNG support.HTML has no required image formats, but over 6.HTML browsers had at least basic support of PNG images.Public comments on this W3.C Recommendation are welcome.Please send them to the archived list png groupw.The latest information regarding patent.Web.
