SVG is one of the formats of two-dimensional vector graphic files that are created on the basis of documents in XML format. The developer is Adobe Systems, and the name of the format is an abbreviation for Scalable Vector Graphics File. In the SVG format, not only two-dimensional vector images can be created, but also mixed vector-raster images. At the same time, SVG files are text files, and therefore they can be opened in most popular text editors. This extension is able to support both static and animated graphics. At the same time, when working with such files, editing occurs without loss of quality.
CGM is an example of an open vector graphics format and an international standard designed to store and share graphic data. We are talking about raster and 2D vector graphics, text. CGM, that is, Computer Graphics Metafile, is a format that is designed to support the needs of various graphics applications. Any graphic element in such a file can be described both in binary and in text format. At first it was used for clip art libraries. However, the new versions, which are based on the ISO / IEC 8632 standard, have found application in automated drawing design. At the moment, the format is used in design, aviation and other technical fields. Consortium World Wide Web Consortium has developed a profile of the use of CGM on the network - WebCGM. CGM files are encoded using three methods. This is binary encoding, that is, file encoding according to the standard. Allows software products to read a file faster. Then comes character-based encryption. Provides the smallest size option, which saves disk space, and also facilitates the rapid transfer of data. The third type of encryption is text based. With it, users will be able to read and understand the contents of the file, as well as modify it using a basic text editor.
