This chunk-based storage layer structure, similar in concept to a container format or to Amiga ' s IFF, is designed to allow the PNG format to be extended while maintaining compatibility with older versions—it provides forward compatibility, and this same file structure (with different signature and chunks) is used in the associated MNG, JNG ...
The PNG (Portable Network Graphics) file format was created as a free, open-source alternative to GIF. The PNG file format supports 8-bit (256 colors) paletted images (with optional transparency for all palette colors) and 24-bit truecolor (16 million colors) or 48-bit truecolor with and without alpha channel – while GIF supports only 8-bit ...

The indigenous peoples of Western New Guinea in Indonesia and Papua New Guinea, commonly called Papuans, [1] are Melanesians.There is genetic evidence for two major historical lineages in New Guinea and neighboring islands: a first wave from the Malay Archipelago perhaps 50,000 years ago when New Guinea and Australia were a single landmass called Sahul and, much later, a wave of Austronesian ...

History of Papua New Guinea. The prehistory of Papua New Guinea can be traced to about 50,000–60,000 years ago, when people first migrated towards the Australian continent. The written history began when European navigators first sighted New Guinea in the early part of the 17th century.
The format supports an optional alpha channel like PNG (but unlike JPEG); and progressive coding, similar to PNG (unlike it, progressive compression doesn't increase file-size), but as FLIF's algorithm is more complex (and partly, may not have had as much tuning of the implementation yet), it has a higher computational cost; at least lower ...
