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. It is also frequently used in memory cards of digital video cameras. Because of the small size, it is requested by the owners of websites, allowing you to save the traffic effectively. It uses the technology of encoding smooth color renditions, providing the ability to frequently reduce the amount of data during the image's recording. □ JPG – is a popular graphic format characterized by a high image compression rate, which leads to a decrease in image quality. The XPS file's supported features include printing schemes, color gradients, transparencies, calibrated printer, CMYK color spaces, and numerous ink systems. Operating systems possess a print spooler format features with the ability to print from printers that are not XPS-aware, producing images that are low in quality compared to those that are XPS-aware. Raster images support HD images it prevents the provision of artifacts and reduces computer processes' work. XAML lets a user add vector-graphic elements since their description is informal and simple terms. It is composed of an organized markup used in determining the outlook of a document, provided for distribution, storing, development, and printing. Ecma International adopted this file format as an international standard ECMA-388. The development of the XPS by Microsoft was intended to create another choice for the PDF. The markup language is a sub-group of XAML, allowing the incorporation of vector-graphics in documents. □ The open XML paper specification is referred to as XPS and is an organized XML markup used to determine how document pages are presented.
