/*
|
|
* 22-2-2003 set devlist to NULL in sane_exit()
|
|
* set first_dev to NULL in sane_exit()
|
|
* eliminated num_devices
|
|
*
|
|
* 23-7-2002 added TL_X > BR_X, TL_Y > BR_Y check in sane_start
|
|
*
|
|
* 17-9-2001 changed ADLIB to AdLib as the comparison is case sensitive and
|
|
* the scanner returns AdLib
|
|
*
|
|
* 7-5-2001 removed removal of '\n' after sanei_config_read()
|
|
* free devlist allocated in sane_get_devices() on sane_exit()
|
|
*
|
|
* 2-3-2001 improved the reordering of RGB data in pie_reader_process()
|
|
*
|
|
* 11-11-2000 eliminated some warnings about signed/unsigned comparisons
|
|
* removed #undef NDEBUG and C++ style comments
|
|
*
|
|
* 1-10-2000 force gamma table to one to one mappping if lineart or halftone selected
|
|
*
|
|
* 30-9-2000 added ADLIB devices to scanner_str[]
|
|
*
|
|
* 29-9-2000 wasn't setting 'background is halftone bit' (BGHT) in halftone mode
|
|
*
|
|
* 27-9-2000 went public with build 4
