A JPEG format where the image information is gradually downloaded. That is, a full-size, low-quality image initially appears, followed by successive passes that improve the image's quality. A progressive JPEG file takes no longer to download than a traditional JPEG file, and the end user can get a good idea of what the final image will look like with only 25 percent of the image downloaded.
A JPEG file format used to display an image progressively in steadily increasing resolutions as data is downloaded in a browser.
an image that displays progressively in a Web browser. The image will display as a series of overlays, enabling viewers to see a low-resolution version of the image before it downloads completely.
an equivalent of "interlaced" GIF
a refinement of the basic JPEG that is broken down into several passes, which are sequentially sent to the Monitor screen
Like the interlaced GIF and PNG files, the progressive JPG file displays an image incrementally, from a rough approximation to the final image. The number of intermediate approximations can be set from 3 to 5.
An enhancement to the JPEG graphics file format specification that gradually displays a photo-realistic picture in a Web browser, showing increasingly detailed versions of the picture until the entire file has finished downloading. While this is similar to interlaced GIFs, progressive JPEGs can retain the high quality of 24-bit color, and they offer the same efficient compression as standard JPEG. See also JPEG.
An image file that appears blurry at first, then gradually comes into focus. (Similar to an interlaced GIF file.)
