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.
JXR is a raster image category file format whose full name is JPEG XR Image. JXR files were created so that you can support better compression and also become more accurate than .JPG files. The development of the image, which is stored in JPEG XR format, has been handled by Microsoft from the very beginning for its Windows Media program. Implements support for images with a color depth of 48 bits of RGB. Used when professional high-resolution image editing is required. Also provides lossy and lossless compression support. JPEG XR, formerly called HD Photo and Windows Media Photo, is an encoding standard. This is the file format for still images. It was patented by Microsoft. This standard supports Windows Vista, like any operating system on which the .NET Framework 3.0 is installed. It defines color formats for printing and displaying. It also defines special encoding in order to expand the dynamic range, lossless and lossy compression functions, as well as efficient decoding for many resolutions with minimal computer resources in order to convert or decode. JPEG XR is inherently high performance. For example, with 85% quality, there are practically no artifacts.
