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.
JBG is a graphic format for raster images, which is usually referred to as the Image JBIG 1-bit Raster file type. The purpose of the format is to store images - both black and white and color. Compared to other similar formats, it has a smaller file size. The .jbg file extension is related to the fact that the image is compressed without loss and is called JBIG. It was developed by the Joint Bi-level Image Experts Group. A .jbg file stores a 1-bit bitmap in JBIG graphic format. It is used as a standard for fax machines. JBIG is a lossless image compression standard. JBIG was developed primarily to compress facsimile images. However, it can be effectively applied to other classes of images. The format uses a variant of arithmetic compression, which is patented by IBM and known as Q-coder. A JBG file is a Jarnal background image. Jarnal is a cross-platform program that is written in Java for notes, thumbnails, and PDF annotations. It functions like a regular notebook with a small difference. It is believed that it can also be used as a stylus on a tablet.
