![]() The software supports more than 4,500 scanner models under Linux and is available in two versions. It uses proprietary drivers and drivers from scanner manufacturers. VueScan is a commercial solution for Linux, which American Ed Hamrickhas been working on since 1999. ![]() Graphical applications like XSane, xscanimage, Simple Scan, or KDE Skanlite all rely on it. This explains why SANE is now considered the quasi-standard for scanners under Linux. Thanks to this concept, all common front ends cooperate with the SANE back end without time-consuming adjustments. ![]() The back end forms the interface between the operating system and the scanner or camera hardware, and the front ends integrate into corresponding applications, making it possible to control the hardware and use its capabilities. It is divided into a front end and a back end, with the two being strictly isolated. ![]() While the TWAIN interface was initially only developed for Microsoft and Apple operating systems, version 2.0 also has supported Linux from 2008.Īt the same time, Linux developers have been working since 1996 on a unified interface for imaging devices called Scanner Access Now Easy (SANE), which they released under the GPLv2. It defines a uniform interface for controlling scanners from within applications. When scanners gradually became affordable for smaller companies in the early 1990s, a consortium of various hardware and software manufacturers developed the TWAIN specification.
