MNG is closely related to the PNG image format. When PNG development started in early 1995, developers decided not to incorporate support for animation, not least of all because this feature of GIF was seldom used at the time. However, work soon started on MNG as an animation-supporting version of PNG. Version 1.0 of the MNG specification was released on January 31, 2001. It has been suggested that libpng be merged into this article or section. ... Animation is the rapid display of a sequence of images of 2-D artwork or model positions in order to create an illusion of movement. ... An example of a GIF image. ...

Software that supports MNG

MNG is currently not as widely supported as PNG. Nonetheless, Konqueror has native MNG support, and MNG plugins are available for most other web browsers. Mozilla browsers and some of Netscape 7.x releases included native support for MNG until the code was removed in 2003 due to code size and little actual usage^[1], causing a huge outcry^[2]. Neither Internet Explorer or Safari currently support MNG. Recent Sony Ericsson phones support MNG files in their themes. Konqueror is a file manager, web browser and file viewer, which was developed as part of the K Desktop Environment (KDE) by volunteers and runs on most Unix-like operating systems. ...

The MNG developers hope that in time MNG will begin to replace GIF for animated images on the World Wide Web, just as PNG has already begun to do for still images.^{[citation needed]} WWWs historical logo designed by Robert Cailliau The World Wide Web (WWW or simply the Web) is a system of interlinked, hypertext documents that runs over the Internet. ...

Technical details

The structure of MNG files is essentially the same as that of PNG files, differing only in the slightly different signature (8A 4D 4E 47 0D 0A 1A 0A in hexadecimal) and the use of a much greater variety of chunks to support all the animation features that it provides. Images to be used in the animation are stored in the MNG file as encapsulated PNG or JNG images. In mathematics and computer science, hexadecimal, base-16, or simply hex, is a numeral system with a radix, or base, of 16, usually written using the symbols 0–9 and A–F, or a–f. ... JNG (IPA ) is a JPEG-based graphics file format which is closely related to PNG. The name stands for JPEG Network Graphics. ...

Two versions of MNG of reduced complexity are also defined: MNG-LC (low complexity) and MNG-VLC (very low complexity). These allow applications to include some level of MNG support without having to implement the entire MNG specification, just as the SVG standard offers the "SVG Basic" and "SVG Tiny" subsets. Scalable Vector Graphics (SVG) is an XML markup language for describing two-dimensional vector graphics, both static and animated, and either declarative or scripted. ...

MNG does not yet have a registered MIME media type, but video/x-mng or image/x-mng can be used. MNG animations may be included in HTML pages using the <object> tag. Multipurpose Internet Mail Extensions (MIME) is an Internet Standard that extends the format of e-mail to support text in character sets other than US-ASCII, non-text attachments, multi-part message bodies, and header information in non-ASCII character sets. ... HTML, short for HyperText Markup Language, is the predominant markup language for the creation of web pages. ...

MNG can either be lossy or lossless, depending whether the frames are encoded in PNG (lossless) or JNG (lossy). JNG (IPA ) is a JPEG-based graphics file format which is closely related to PNG. The name stands for JPEG Network Graphics. ...

Alternatives

GIF is often used. APNG is proposed as an alternative to MNG. Yet another alternative would be using animated SVG images with embedded PNG or JPEG graphics. An example of a GIF image. ... The APNG (Animated Portable Network Graphics) file format is a proposed extension to the portable network graphics (PNG) specification that would allow for animated PNG files that work in a similar fashion to animated graphics interchange format (GIF) files, while retaining the backward compatibility with non-animated PNG files. ... Scalable Vector Graphics (SVG) is an XML markup language for describing two-dimensional vector graphics, both static and animated, and either declarative or scripted. ... In computing, JPEG (pronounced JAY-peg; IPA: ) is a commonly used standard method of compression for photographic images. ...
