JPM is a JPEG2000 bitmap category file format. The JPEG 2000 Part 6 standard defines that the .jpm extension refers to the JPEG 2000 Composite Image File Format. The JPEG2000 graphic format is a new standard that appeared in 2000 as an update to the JPEG format. He uses a type of technology called wavelet compression, which provides the best ratio of size and quality. The JPM format (i.e., the JPEG 2000 Multi-layer Image Format, ISO 15444-6) was developed for documents that have multiple pages and can be processed as a multi-page photo converter. The purpose of the JPEG 2000 Part 6 composite image format is to work primarily with documents and facsimile images. Compared to regular JPEG 2000 images, a .jpm file is a composite image with many layers. This file can have many pages. Moreover, each such page can have several raster objects. Moreover, in different encodings (JPEG, JPEG 2000, JBIG). They are located in a certain way and make up a single whole. JPM files are used as “digital originals” that store scanned copies of documents and other images and / or texts.
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.
