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.
ODT is one of the options for the text file format, which was in little demand and gained relative distribution only in 2014, when Google Docs began to use the ODF format. It takes its name from the OpenDocument Text Document, and is used in office programs that are based on utilities like Open Office or LibreOffice. The open standard ODF (OpenDocument Format) was created by the OASIS community and was intended for the free creation, editing, storage and exchange of office documents. Within its framework, the ODT format also allows the use of databases, presentations, images, tables in text files.
