NAME<\/a> sane\u2212sceptre \u2212 SANE backend for SCEPTRE scanners<\/p>\n The sane\u2212sceptre<\/b> library implements a SANE (Scanner Access Now Easy) backend that provides access to Sceptre flatbed scanners. This backend should be considered beta-quality<\/b> software! Please report any strange behavior to the maintainer of the backend or to the SANE mailing list.<\/p>\n At present, only one scanner is known to work with this backend:<\/p>\n Model Connection Type The make of this scanner is KINPO, so other scanners from that manufacturer may also work (eg. the S600).<\/p>\n The options the backend supports can either be selected through command line options to programs like scanimage<\/b>(1) or through GUI elements in xscanimage<\/b>(1) or xsane<\/b>(1).<\/p>\n Valid command line options and their syntax can be listed by using<\/p>\n scanimage \u2212\u2212help \u2212d sceptre<\/p>\n Scan Mode Selects the basic mode of operation of the scanner. The Lineart<\/i> and Halftone<\/i> mode are black and white only (1 bit). Gray<\/i> will produce 256 levels of gray (8 bits). Color<\/i> will produce a 24 bits color image. The scanner supports 30 bits internally but it only exports 24.<\/p>\n \u2212\u2212resolution 50..1200<\/b><\/p>\n Selects the resolution for a scan. The scanner can do several resolutions between 50 and 1200.<\/p>\n \u2212\u2212halftone\u2212pattern 1|2|3|4<\/b><\/p>\n Selects the pattern mode that is used in Halftone<\/i> mode.<\/p>\n \u2212\u2212gamma\u2212correction Default|User Defined|High Density Printing|Low controls the scanner internal gamma correction.<\/p>\n \u2212\u2212custom\u2212gamma<\/b><\/p>\n Allows the user to specify a gamma table (see the next 3 parameters). Color<\/i> mode only.<\/p>\n \u2212\u2212red\u2212gamma\u2212table<\/b><\/p>\n Can be used to download a user defined gamma table for the red channel. The table must be 256 bytes long. Color<\/i> mode only.<\/p>\n \u2212\u2212green\u2212gamma\u2212table<\/b><\/p>\n Can be used to download a user defined gamma table for the green channel. The table must be 256 bytes long. Color<\/i> mode only.<\/p>\n \u2212\u2212blue\u2212gamma\u2212table<\/b><\/p>\n Can be used to download a user defined gamma table for the blue channel. The table must be 256 bytes long. Color<\/i> mode only.<\/p>\n \u2212\u2212threshold 0..255<\/b><\/p>\n Sets the threshold for black and white pixels in Lineart<\/i> mode. Possible values are from 0 (darker) to 255 (lighter).<\/p>\n \u2212\u2212preview<\/b><\/p>\n Requests a preview scan. The resolution used for that scan is 30 dpi and the scan area is the maximum allowed. The scan mode is user selected. The default is “no”.<\/p>\n The geometry options control the scan area: -l<\/b> sets the top left x coordinate, \u2212t<\/b> the top left y coordinate, \u2212x<\/b> selects the width and \u2212y<\/b> the height of the scan area. All parameters are specified in millimeters by default.<\/p>\n The configuration file \/etc\/sane.d\/sceptre.conf<\/i> supports only one item: the device name to use (eg \/dev\/scanner<\/i>).<\/p>\n \/usr\/lib64\/sane\/libsane\u2212sceptre.a<\/i><\/p>\n The static library implementing this backend.<\/p>\n \/usr\/lib64\/sane\/libsane\u2212sceptre.so<\/i><\/p>\n The shared library implementing this backend (present on systems that support dynamic loading).<\/p>\n SANE_DEBUG_SCEPTRE<\/b><\/p>\n If the library was compiled with debug support enabled, this environment variable controls the debug level for this backend. E.g., a value of 128 requests all debug output to be printed. Smaller levels reduce verbosity.<\/p>\n Resolutions<\/b><\/p>\n The windows TWAIN driver can be set to any resolution between 50 to 1200 (excluding software interpolation). This backend cannot. Only a handful of resolution are available, although they should be numerous enough.<\/p>\n None known.<\/p>\n
