BPG – there comes the end of the JPEG format?
The famous French programmer Fabrice Belar (author of the emulator QEMU, compiler Tiny C, archiver LZEXE etc.) Developed a new graphic format, having all chances to become the successor to JPEG in the near future. The format BPG (Better Portable Graphics) provides a higher degree of compression of JPEG. However, he kept gradient transitions and many fine details. The difference is particularly strong in compression. Where the photos in the JPEG artifacts abound, the same shots in BPG seem perfectly acceptable, and files take up less space.
Each such file starts with hex-header 42 50 47 (BPG). Further, the image is similar to that described as in the open standard compression HEVC (H.265), originally designed for the compression of video streams. An important feature of BPG is the ability to store the alpha channel (transparent layer), which partly makes competitor and other popular web formats – PNG and GIF. Furthermore, the alpha channel, BPG supports storage of all metadata.
BPG supports color models RGB, CMYK and YcgCo, in this 14 bit resolution per channel instead of 8 as in JPEG. This allows for the storage of a greater amount of halftone and provides more options for further processing similar to TIFF.
Recall that in July this year, Mozilla conducted tests on another format for compression of images – MozJPEG 2.0. Company Facebook, extremely interested in optimizing the consumer photographs on their servers departments to develop a sum of $60,000.
BPG requires much less storage space, but now browsers have to built-in support for it. Fabrice Belar himself presents his development as a fully open standard. He has published a detailed description of the form and applied source of JS decoder. Compiled console version for Windows is available at the author’s website.
For now, the question remains open with copyright clarification of which will happen after legal expertise, as the patent on the original algorithm HEVC belongs to MPEG LA. Extent how much of it its borrowed from Belar is unknown.http://szlifestyle.com/sz/2014/12/30/bpg-there-comes-the-end-of-the-jpeg-format/https://i0.wp.com/szlifestyle.com/sz/wp-content/uploads/2014/12/sz_MozJPEG-vs_BPG.jpg?fit=640%2C440https://i0.wp.com/szlifestyle.com/sz/wp-content/uploads/2014/12/sz_MozJPEG-vs_BPG.jpg?resize=150%2C150TECH NEWSTechnologyThe famous French programmer Fabrice Belar (author of the emulator QEMU, compiler Tiny C, archiver LZEXE etc.) Developed a new graphic format, having all chances to become the successor to JPEG in the near future.
