| | JPEG 2000 - Wikipedia, the free encyclopedia |
 | | JPEG 2000 is not widely supported in present software due to the perceived danger of software patents on the mathematics of the compression method, this area of mathematics being heavily patented in general. | | | The PNG and JPEG 2000 in future will be used in the same way that GIF and JPEG were used in the 1980s-1990s. | | | Although JPEG 2000 format supports lossless encoding, it is not intended to completely supersede today's dominant lossless image file formats. |

| | GRAPHICS: JPEG graphics |
| | The JPEG algorithm was optimized for compressing conventional pictorial photographs and is also good at handling complex illustrations. | | | This is possible because the JPEG algorithm discards "unnecessary" data as it compresses the image, and it is thus called a "lossy" compression technique. | | | The JPEG algorithm is best at compressing smooth tonal transitions and cannot properly reproduce the harsh transitions at the edges of diagrammatic graphics. |

| | 1) JPEG (Joint Photographic Experts Group) is an ISO/IEC group of experts that develops and maintains standards for a suite of compression algorithms for computer image files. | | | Together with the Graphic Interchange Format (GIF) and Portable Network Graphics (PNG) file formats, the JPEG is one of the image file formats supported on the World Wide Web, usually with the file suffix of ".jpg". | | | Since the highest quality results in the largest file, you can make a trade-off between image quality and file size. |

| | The only real solution is to combine lossy JPEG storage of the image with lossless storage of a transparency mask using some other algorithm. | | | JPEG does not support transparency and is not likely to do so any time soon. | | | Most production-quality JPEG programs use only integer arithmetic and so they are unaffected by the presence or absence of floating-point hardware. |

| | JPEG (also known as JPG) files can support up to millions of colors unlike GIF files which are limited to a maximum of 256 colors. | | | or jpeg -- one of the most popular forms of Web graphics (the other is gif), jpegs usually provide sharper images, but also take longer to load onto a Web page; named for the committee that designed the standard image compression algorithm, the Joint Photographic Experts Group. | | | To conserve disk space and transfer time, a JPEG image can be compressed to varying degrees using a "lossy" method (meaning the resulting image is not of the same quality as the original.) |

| | The problem with JPEG is that to make the file smaller, the computer in your camera actually throws away some of the data when saveing to the memory card; how much depends on what "quality" setting you are useing. | | | Then, when you open the image in an editing program your computer writes the data back. | | | Also, some cameras take longer to actually write them to the memory card. |

| | Raster or bitmapped files are used to depict continuous tone, photographic and grey-scale images - images captured by a scanner, manipulated by image-editing software programs or created by a paint program. | | | Vector files are modified very easily, have very small file sizes, and the resolution is determined by the output device - the image is drawn via algorithmic instruction. | | | High res raster scans should not be scaled up more than 10% or down more than 30% without affecting final output quality. |
