![]() Mitchell – Probability adaptation for arithmetic coders Rissanen – Arithmetic coding encoder and decoder system Rissanen – Multiplication-free multi-alphabet arithmetic code The following patents provided the basis for its arithmetic coding algorithm. The JPEG specification cites patents from several companies. The original JPEG specification published in 1992 implements processes from various earlier research papers and patents cited by the CCITT (now ITU-T) and Joint Photographic Experts Group. In 2000, the JPEG group introduced a format intended to be a successor, JPEG 2000, but it was unable to replace the original JPEG as the dominant image standard. JPEG files usually have a filename extension of "jpg" or "jpeg." JPEG/JFIF supports a maximum image size of 65,535×65,535 pixels, hence up to 4 gigapixels for an aspect ratio of 1:1. ![]() The MIME media type for JPEG is "image/jpeg," except in older Internet Explorer versions, which provide a MIME type of "image/pjpeg" when uploading JPEG images. These format variations are often not distinguished and are simply called JPEG. ![]() JPEG/ Exif is the most common image format used by digital cameras and other photographic image capture devices along with JPEG/ JFIF, it is the most common format for storing and transmitting photographic images on the World Wide Web. JPEG compression is used in a number of image file formats. JPEG was largely responsible for the proliferation of digital images and digital photos across the Internet and later social media. The term "JPEG" is an acronym for the Joint Photographic Experts Group, which created the standard in 1992. Since its introduction in 1992, JPEG has been the most widely used image compression standard in the world, and the most widely used digital image format, with several billion JPEG images produced every day as of 2015. JPEG typically achieves 10:1 compression with little perceptible loss in image quality. The degree of compression can be adjusted, allowing a selectable tradeoff between storage size and image quality. JPEG ( / ˈ dʒ eɪ p ɛ ɡ/ JAY-peg, short for Joint Photographic Experts Group) is a commonly used method of lossy compression for digital images, particularly for those images produced by digital photography. ![]() Yet the program itself is already very stable and no crash ever occurred to me.Continuously varied JPEG compression (between Q=100 and Q=1) for an abdominal CT scan The only downside of XnViewMP is amount of small bugs, but keep in mind, this program didn't achieve the version 1.0 yet, and the author releases new versions and bug fixes very frequently. It can do all the basic photo editing tasks and perform batch editing/renaming. Indeed, XnViewMP starts and responds really fast without any lagging, and the possibilities of UI customization using the QSS style sheets are just brilliant! Feature-wise, XnViewMP is very similar to Zoner. I was very excited to find out this program is based on Qt framework, which proves this framework is a perfect choice for multi-platform user programs. Then, I found XnViewMP, which surprised me in a nice way. I have tried Adobe Bridge, but that program is very slow to start and heavy, like all products from Adobe. Therefore, I started to look for an alternative to Zoner. I would even say, the UI got worse for desktop users.įinally, introducing the new controversial subscription license, their intrusive marketing strategy and pushing Facebook to the main folder tree navigator (without any option to hide it), made me give up this program completely. I have been testing demos of their new versions, but there isn't anything worth of upgrading for me. Since that version, Zoner has decided to go in the way of simplifying the user interface for tablets, rather than to introduce more desktop friendly features and more powerful keyboard shortcuts. However, the last version of Zoner, I have purchased and still use, is the version 15. You can use batch filters not only to resize/rename images, but also you can use all the photo editing tools or edit EXIF metadata. The very strong side of Zoner are batch editing tools. ![]() It's a very convenient program enabling you to do all the essential photo editing tasks like curves, levels, color temperature, etc. For a very long time, I have been using Zoner Photo Studio as a photo manager and file explorer. ![]()
