JPF is a raster image category file format that is the successor to the .JPEG image format. Like some other file name extensions (.jpx, .jp2, .j2k), the .jpf extension refers to the JPEG 2000 image format. It is needed to designate the JPEG 2000 Image file type. And JPEG 2000 files are an international standard (ISO / IEC 15444) bitmap format. It was developed by the Joint Photographic Experts Group, JPEG. It serves as a good replacement for the JPEG standard, which is older, but, as before, is in demand and widespread. Compared to JPEG in JPF format, wavelet compression is used, due to the alpha channel transparency is supported, as well as a variety of color models. Also, compared to JPEG, this format provides better scalability of images, provides the ability to achieve smaller file sizes and have a higher level of quality. The format is able to combine compression with losses and without losses. Provides support for image transparency and additional metadata information. It can be viewed in QuickTime Player 7, as in recent versions of Photoshop, provided that the JPEG2000.8bi plugin is installed. Many images also have the extension .JP2 or .JPX.
J2C is an advanced version of the JPEG format, which is now widely adopted in order to transfer and store digital images. This is a raster image category file. Full name - JPEG 2000 Code Stream. The J2C file format was created by Joint Photographic Experts Group. A format is a lot of advanced features, including efficient coding. The .j2c file extension is a JPEG 2000 image file. This bitmap is created using JPEG 2000 compression. The compression is close to standard .JPG compression. However, it uses a new coding standard, and it is flexible due to computational complexity. Many applications that support standard .JP2 files can view it. A file with the J2C extension opens in the Windows operating system. To view and process a bitmap image in J2C format, you need to use programs such as Corel PaintShop Pro X9, IvanView, ACD Systems Canvas 16, ImageMagick. Using the programs that have been listed, you can convert images, pictures and drawings of the specified format.
