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.
ODS is a spreadsheet received using StarOffice, OpenOffice, and other office suite programs. This table is created in the Calc application, and it is part of the free Apache OpenOffice office suite. An ODS file (Open Document Spreadsheet) stores all the data in cells, which are rows and columns. He is able to additionally have text, graphic elements, diagrams. Note that the ODS format is not always tables. It also happens that this is a mailbox or archive for electronic messages. Then it is created or saved in Outlook Express. The file format is based on OASIS, which is an open document format for office applications. All file data is in the form of XML. The OpenDocument standard can be used by everyone. And there are no restrictions. The ODS format is unlimited for any office application. Its source code is open, that is, it is a good alternative to Microsoft's proprietary format (.xls). Those who choose Microsoft Office will not need conversions. Excel in the 2007 version, which includes the second service pack, is able to support this format. To adapt such a document with an earlier version of the spreadsheet editor, the Sun ODF plug-in is installed.
