SVG is one of the formats of two-dimensional vector graphic files that are created on the basis of documents in XML format. The developer is Adobe Systems, and the name of the format is an abbreviation for Scalable Vector Graphics File. In the SVG format, not only two-dimensional vector images can be created, but also mixed vector-raster images. At the same time, SVG files are text files, and therefore they can be opened in most popular text editors. This extension is able to support both static and animated graphics. At the same time, when working with such files, editing occurs without loss of quality.
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.
