This backend +should be considered +.B beta-quality +software! LEO scanners were also sold under the Across Technologies brand. +.PP +The scanners that should work with this backend are: +.PP +.RS +.ft CR +.nf + Vendor Model status +---------------------- ----------- + Across FS-1130 tested + LEO S3 tested +.fi +.ft R +.RE + +The options the backend supports can either be selected through +command line options to programs like +.BR scanimage (1) +or through GUI elements in +.BR xscanimage (1) +or +.BR xsane (1). + +.br +If you have any strange behavior, please report to the backend +maintainer or to the SANE mailing list. + +Valid command line options and their syntax can be listed by using +.RS +scanimage \-\-help \-d leo +.RE + +.TP +.B Scan Mode + +.TP +.B \-\-mode +selects the basic mode of operation of the scanner. Valid choices are +.IR "Black & White" , +.I Grayscale +and +.IR Color . +The +.I Black & White +mode is black and white only (1 bit). +.I Grayscale +mode will produce 256 levels of gray (8 bits). +.I Color +mode will produce a 24 bit color image. + +.TP +.B \-\-resolution +selects the resolution for a scan. The scanner can do all resolutions +between 1 and 300, in increments of 1. + + +.TP +.B Geometry options + +.TP +.B \-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 by default. + + +.TP +.B Enhancement options + +.TP +.B \-\-custom\-gamma +(grayscale and color mode only) allows the user to specify a gamma table (see the +next 3 parameters). + +.TP +.B \-\-red\-gamma\-table +(color mode only) can be used to download a user defined +gamma table for the red channel. The table must be 256 bytes long. + +.TP +.B \-\-green\-gamma\-table +(color mode only) can be used to download a user defined +gamma table for the green channel. The table must be 256 bytes long. + +.TP +.B \-\-blue\-gamma\-table +(color mode only) can be used to download a user defined gamma table +for the blue channel. The table must be 256 bytes long. + +.TP +.B \-\-halftone +(Black & White only) select the halftone mask to use. Possible values are +.IR Diamond , +.IR "8x8 Coarse Fatting" , +.IR "8x8 Fine Fatting" , +.I 8x8 Bayer +and +.IR "8x8 Vertical Line" . + +.TP +.B \-\-preview +requests a preview scan. The resolution used for that scan is 28 dpi +and the scan area is the maximum allowed. The scan mode is user +selected. The default is "no". + + +.SH CONFIGURATION FILE +The configuration file +.I /etc/sane.d/leo.conf +supports only one information: the device name to use (eg +.IR /dev/scanner ). + + +.SH FILES +.TP +.I /usr/lib/x86_64-linux-gnu/sane/libsane\-leo.a +The static library implementing this backend. +.TP +.I /usr/lib/x86_64-linux-gnu/sane/libsane\-leo.so +The shared library implementing this backend (present on systems that +support dynamic loading). + + +.SH ENVIRONMENT +.TP +.B SANE_DEBUG_LEO +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. + + +.SH LIMITATIONS +The windows TWAIN driver has many more options than this SANE +backend. However they are only software adjustments. This backend only +implements what the scanner can support. + + +.SH BUGS +None known. + + +.SH "SEE ALSO" + +.BR sane\-scsi (5), +.BR scanimage (1), +.BR xscanimage (1), +.BR xsane (1), +.BR sane (7) + + +.SH AUTHOR + +.TP +The package is actively maintained by Frank Zago. +.I http://www.zago.net/sane/#leo |
