|
* @brief SANE backend for Plustek scanner
|
|
*
|
|
* Based on Kazuhiro Sasayama previous work on
|
|
* plustek.[ch] file from the SANE package.<br>
|
|
* Original code taken from sane-0.71<br>
|
|
* Copyright (C) 1997 Hypercore Software Design, Ltd.<br>
|
|
* Also based on the work done by Rick Bronson<br>
|
|
* Copyright (C) 2000-2007 Gerhard Jaeger <gerhard@gjaeger.de><br>

|
* - 0.34 - moved some definitions and typedefs to plustek.h
|
|
* - 0.35 - removed Y-correction for 12000P model<br>
|
|
* - getting Y-size of scan area from driver
|
|
* - 0.36 - disabled Dropout, as this does currently not work<br>
|
|
* - enabled Halftone selection only for Halftone-mode<br>
|
|
* - made the cancel button work by using a child process during read<br>
|

|
|
* - cleaned up the code<br>
|
|
* - fixed sane compatibility problems<br>
|
|
* - added multiple device support<br>
|
|
* - 12bit color-depth are now available for scanimage
|
|
* - 0.37 - removed X/Y autocorrection, now correcting the stuff
|
|
* before scanning
|
|
* - applied Michaels' patch to solve the sane_get_parameter problem<br>
|
|
* - getting X-size of scan area from driver<br>
|
|
* - applied Michaels patch for OPT_RESOLUTION (SANE_INFO_INEXACT stuff)
|
|
* - 0.38 - now using the information from the driver
|
|
* - some minor fixes<br>
|
|
* - removed dropout stuff<br>
|
|

|
|
* - added WIFSIGNALED to check result of child termination
|
|
* - changed readImage interface for USB devices
|
|
* - homeing of USB scanner is now working correctly
|
|
* - 0.46 - added plustek-usbcal.c for extra CIS device calibration
|
|
* based on Montys' great work
|
|
* - added altCalibration option
