Mind that raster pictures are resolution-dependent. The JPG file is a great format as it often manages to compress files to 1/10 of the size of the original file which is especially good for saving on bandwidth. unitary, binary, unstructured, sampled, Last significant FDD update: It was developed by the Independent JPEG Group and C-Cube Microsystems, in the absence of any such format being defined in the JPEG standard, and rapidly became a de facto standard; this is what is commonly referred to as the JPEG file format. It does not say how to interpret those numbers as an image. My Picture Screen Saver displays multiple image files one at a time.

A JPEG file interchange format file is generally classified as an image file integrated with digital graphics encoding specifications also implemented into JPEG files, though the content of a JPEG file interchange format file is the compressed version of the corresponding JPEG file. The file extensions can be.jpg,.jpeg,.jp2. Information technology -- Digital compression and coding of continuous-tone still images: JPEG File Interchange Format (JFIF), JPEG File Interchange Format, The decoder will just have to guess. The specification for JFIF 1.02 was originally published in 1992, and made available publicly at http://www.jpeg.org/public/jfif.pdf. Paraphrased from James D. Murray and William vanRyper's Encylopedia of Graphics File Formats (O'Reilly and Assoc, 1994, ISBN 1565920589): The JPEG bitstream stores 16-bit word values in big-endian format. Version 1.02 (1992); formerly available at, Very widely adopted, surpassing the use of either "raw" JPEG bitstreams or the, Limited, but some techical metadata is provided by the application segment APP0, and some can be derived in other ways.
