SANE backend for SCEPTRE scanners

## NAME

sane-sceptre - SANE backend for SCEPTRE scanners

## DESCRIPTION

The **sane-sceptre** library implements a SANE (Scanner Access Now Easy) backend that provides access to Sceptre flatbed scanners. This backend should be considered **beta-quality** software! Please report any strange behavior to the maintainer of the backend or to the SANE mailing list.

At present, only one scanner is known to work with this backend:

```
Model                        Connection Type
---------------------------  -------------------
Sceptre VividScan S1200      SCSI
```

The make of this scanner is KINPO, so other scanners from that manufacturer may also work (eg. the S600).

## OPTIONS

The options the backend supports can either be selected through command line options to programs like [**scanimage**(1)](/scanimage/1.md) or through GUI elements in [**xscanimage**(1)](/xscanimage/1.md) or [**xsane**(1)](/xsane/1.md).

Valid command line options and their syntax can be listed by using

scanimage --help -d sceptre

- **Scan Mode**

  - **--mode Lineart\|Halftone\|Gray\|Color**

  Selects the basic mode of operation of the scanner. The *Lineart* and *Halftone* mode are black and white only (1 bit). *Gray* will produce 256 levels of gray (8 bits). *Color* will produce a 24 bits color image. The scanner supports 30 bits internally but it only exports 24.

- **--resolution 50..1200**

  Selects the resolution for a scan. The scanner can do several resolutions between 50 and 1200.

- **--halftone-pattern 1\|2\|3\|4**

  Selects the pattern mode that is used in *Halftone* mode.

- **--gamma-correction Default\|User Defined\|High Density Printing\|Low density printing\|High contrast printing**

  controls the scanner internal gamma correction.

- **--custom-gamma**

  Allows the user to specify a gamma table (see the next 3 parameters). *Color* mode only.

- **--red-gamma-table**

  Can be used to download a user defined gamma table for the red channel. The table must be 256 bytes long. *Color* mode only.

- **--green-gamma-table**

  Can be used to download a user defined gamma table for the green channel. The table must be 256 bytes long. *Color* mode only.

- **--blue-gamma-table**

  Can be used to download a user defined gamma table for the blue channel. The table must be 256 bytes long. *Color* mode only.

- **--threshold 0..255**

  Sets the threshold for black and white pixels in *Lineart* mode. Possible values are from 0 (darker) to 255 (lighter).

- **--preview**

  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".

- **The geometry options**

  - **-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.

## CONFIGURATION FILE

The configuration file */etc/sane.d/sceptre.conf* supports only one item: the device name to use (eg */dev/scanner*).

## FILES

- */usr/lib/sane/libsane-sceptre.a*

  The static library implementing this backend.

- */usr/lib/sane/libsane-sceptre.so*

  The shared library implementing this backend (present on systems that support dynamic loading).

## ENVIRONMENT

- **SANE\_DEBUG\_SCEPTRE**

  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.

## LIMITATIONS

- **Resolutions**

  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.

## BUGS

None known.
