XSane is a graphical program for accessing scanners and other image acquisition devices through SANE. It can preview images and scan from devices such as flatbed scanners, with available hardware depending on the installed device and configuration. Its viewer, save, copy, fax, and mail modes cover several ways to handle an acquired image. Used on its own, XSane saves scans as PNM or converts them to JPEG, PNG, PS, or TIFF. It can also send an image to a printer or serve as a frontend to a fax program. XSane can be invoked through The GIMP to pass images there for further processing. SANE also includes a network protocol for accessing image acquisition devices over a network. The listed features include color management, gamma enhancement, and a histogram. XSane is free, requires a SANE-compatible scanner, and is listed for Linux and Windows. Its source description also names OS/2 and various Unix systems; package dependencies include SANE and GTK 2.
