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.
JPT is a file extension belonging to the JPEG 2000 bitmap file category (versions .jp2, .j2k, .jpt and others) and the JPEG 2000 file format. JPEG 2000 format is defined as a system for encoding and transmitting graphic raster files. It was developed by the Joint Photographic Experts Group (JPEG). It is approved by a series of ISO / ITU standards. The JPEG 2000 standard, which was designed from the very beginning to replace traditional JPEG, applies wavelet compression with and without loss. It gives an increased compression ratio and surpasses JPEG by all standards. The standard method for designating JPEG 2000 files is the .jp2 extension. However, other extensions are also used for this. In particular, .jpt. A .jpt file is a JPEG 2000 compressed image. It is saved in the JPT codestream version, where the name means “JPIP Tile-part”. This is a segmented part of JPIP, or the JPEG 2000 interactive protocol. This is the standard JPEG 2000 image streaming protocol. It is oriented to get maximum efficiency and quick access to graphic data. JPT is one of two standard streaming modes. The second mode is called JPP, JPIP Precinct.
