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.
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.
