![]() ![]() In this case, the reduction in image quality can vary from insignificant to substantial. The file compression ratio is in the range from 10:1 to 100:1. The format acts simultaneously as the standard of ISO and the International Telecommunication Union. JPEG uses a "lossy" compression system and discrete cosine transform technology. Finally, the colors and brightness are coded. First, the photo is transformed into a color space YCbCr, and then it is divided into squares to determine the upper range of the color spectrum. □ The procedure for compressing the digital images in JPG format is carried out in several stages. A strong contrast between several near located pixels provokes the appearance of visible artifacts. It is not recommended to use this format for compression of drawings and various kinds of graphics. ![]() The JPG algorithm is optimally suitable for compressing photographs and pictures in which realistic scenes with little contrast of colors are present.

The range of available GIF colors is from 2 (black and white) to 256 while reducing the number of colors leads to a decrease in the file size. Reducing the number of colors required to create an image is provided by removing shades unnecessary to perform this process. Scan-line data is compressed to the smallest size. Interlaced data storage is also possible. Thanks to the Lempel-Ziv-Welch algorithm, the format handles graphic files with repeating sections well, particularly images with a large number of single-color pixels horizontally. This ensures the preservation of high-quality pictures. The extension uses the LZW algorithm to carry out a parallel process with the removal of segments containing insufficient information. □ The format was developed by Compuserve specialists, especially for its use in the web environment, which provided broad public access to data on such files.

They use scan-line images with the depth parameters up to 256 colors of the RGB palette. Such files are used to develop web advertising with sequentially changing pictures and the graphics shell of video files. It also supports transparent views of various animations. □ GIF, Graphics Interchange Format, is one of the most popular bitmap image formats on the World Wide Web, allowing you to share images.
