Valid choices +are Lineart, Gray and Color. The Lineart mode is black and white only, +Gray will produce 256 levels of gray or more depending on the scanner +and Color means 24 bit color mode or more depending on the scanner. +Some scanners will internally use 36 bit color, their external interface +however may only support 24 bits. + +The +.I \-\-depth +option selects the bit depth the scanner is using. This option is only +available for scanners that support more than one bit depth. Older +scanners will always transfer the image in 8bit mode. Newer scanners +allow to select either 8 bits, 12 or 14 bits per color channel. For a +color scan this means an effective color depth of 36 or 42 bits over +all three channels. The valid choices depend on the scanner model. + +The +.I \-\-resolution +switch selects the resolution for a scan. Some EPSON scanners will scan in +any resolution between the lowest and highest possible value. The list +reported by the scanner can be displayed using the "\-\-help \-d epson" +parameters to scanimage. + +The geometry options +.I \-l \-t \-x \-y +control the scan area: \-l sets the top left x coordinate, \-t the top +left y coordinate, \-x selects the width and \-y the height of the scan +area. All parameters are specified in millimeters. + +The +.I \-\-source +option selects the scan source. Valid options depend on the installed +options. The default is "Flatbed". + +The +.I \-\-eject +option ejects the sheet in the ADF. + +The +.I \-\-adf-mode +option select the ADF mode (simplex/duplex). + +.SH CONFIGURATION FILE +The configuration file @CONFIGDIR@/epsonds.conf specifies the device(s) that the +backend will use. Possible connection types are: +.TP +.I USB +For not automatically detected USB scanners, their VENDOR and PRODUCT ID can +be specified manually in the config file. +More information about valid syntax for USB devices can be found in sane\-usb(5). +.TP +.I Network (not yet supported) +Network scanners can be auto-discovered if +.I autodiscovery +is specified after +.I +net +keyword. An IP address to connect to can also be used. +.SH FILES +.TP +.I @LIBDIR@/libsane\-epsonds.a +The static library implementing this backend. +.TP +.I @LIBDIR@/libsane\-epsonds.so +The shared library implementing this backend (present on systems that +support dynamic loading). +.SH ENVIRONMENT +.TP +.B SANE_DEBUG_EPSONDS +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. Values around 11-16 will usuallybe enough for +a bug report. + +.SH "SEE ALSO" + +sane\-usb(5), scanimage(1), xscanimage(1), xsane(1) + +.SH AUTHOR + +The package is written by Alessandro Zummo |
