The ability to scan papers is a common thing for each modern office. Image scanner is a device that optically scans papers and converts them to digital images.
TWAIN is a standard that regulates communication between software application and scanner or camera that has a TWAIN device driver called Data Source.
SANE stands for "Scanner Access Now Easy" and is an application programming interface (API) that provides standardized access to any raster image scanner hardware.
VintaSoft Twain .NET SDK is the professional .NET image scanning SDK, which allows to work with TWAIN and SANE devices in Windows and Linux. Scanned images can be processed, saved to a file or uploaded to HTTP(S) or FTP server.
