JPC is a bitmap image format that uses advanced JPEG 2000 wave compression. It is classified as a JPEG 2000 Code Stream File. JPEG 2000, in turn, is a popular standard for compressing wavelet image data. The .JPC extension supports color depths of 8, 24, and 32 bits per pixel. Also supports grayscale, RGB, YCbCr, XYZ and Lab color space. The file was developed by the standards committee of the Joint Photographic Experts Group. JPC is the successor to the JPEG image format, which is very popular and very common. The updated format is able to provide many additional features. In particular, color spaces. JPC has also gained fame as a variant of JPEG2000. It belongs to a large group of formats that bring a variety of updates to the original JPEG format. For example, J2C, JPM, or J2K. The .jpc file extension is a JPEG 2000 image stream file. This file can be opened using programs such as Corel PaintShop Pro X9, Adobe Photoshop Elements 14, Adobe Photoshop CC, ACD Systems ACDSee 20. You can also save memory snapshot files in the format JPC These JPC files are used by Java application developers.
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.
