JP2 is a bitmap image format. The JP2 format, i.e. JPEG 2000 image, was developed by the Joint Photographic Experts Group. The JP2 file can be in the form of a photograph, drawing, digital fax, etc. File type: JPEG 2000 Core Image File. JPEG 2000 is the patent-pending bitmap image format. It has been licensed free of charge, and now it is an international standard (ISO / IEC 15444-1: 2004). Compared to the previous JPEG-1 standard, JPEG 2000 uses a completely different method to compress data (wavelet transform, wavelet transform). This method generally ensures higher image quality. It also gives a more compact file size. The JP2 format has a lot in common with the JPEG format, which is now especially popular. However, it differs in that it uses wavelet transform technology for compression, and discrete cosine transform has found application in JPEG. Using the first technology, you can get a better image, even when the file size is relatively smaller. There are also JP2 files with the extensions .J2K, JPF, MJ2, JPX and JPM. In order to open a file of this format, that is, to edit, use programs such as Mozilla Firefox, Adobe Photoshop, ACD Systems ACDSee, Google Chrome.
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.
