Values are only printed for + Debug levels >= 10. + 2000-12-04 We've introduced the concept of inverting images + when scanning from a TPU.

So, we have to back into + the proper gamma table. I think this works. See + set_gamma_table. (mjp) + 2000-12-03 added the 12/14/16 bit support again. + 2000-12-03 Version 0.1.38 + removed changes regarding 12/14 bit support because + of SANE feature freeze for 1.0.4.

(mjp) + 2000-05-28 Turned on scanner based color correction. + Dependancies between many options are now + being enforced. For instance, auto area seg + (AAS) should only be on when scan depth == 1. + Added some routines to active and deactivate + options. Routines report if option changed. + Help prevent extraneous option reloads. Split + sane_control_option in getvalue and setvalue. + Further split up setvalue into several different + routines. (mjp) + 2000-05-21 In sane_close use close_scanner instead of just the + SCSI close function. + 2000-05-20 ... finally fixed the problem with the 610 + Added resolution_list to Epson_Device structure in + epson.h - this fixes a bug that caused problems when + more than one EPSON scanner was connected. + 2000-05-13 Fixed the color problem with the Perfection 610. The few + lines with "garbage" at the beginning of the scan are not + yet removed. + 2000-05-06 Added support for multiple EPSON scanners. At this time + this may not be bug free, but it's a start and it seems + to work well with just one scanner. + 2000-04-06 Did some cleanup on the gamma correction part. The user + defined table is now initialized to gamma=1, the gamma + handling is also no longer depending on platform specific + tables (handled instead by pointers to the actual tables) + 2000-03-27 Disable request for push button status + 2000-03-22 Removed free() calls to static strings to remove + compile warnings. These were introduced to apparently + fix an OS/2 bug. It now turned out that they are not + necessary. The real fix was in the repository for a + long time (2000-01-25). + 2000-03-19 Fixed problem with A4 level devices - they use the + line mode instead of the block mode. The routine to + handle this was screwed up pretty bad. Now I have + a solid version that handles all variations of line + mode (automatically deals with the order the color + lines are sent). + 2000-03-06 Fixed occasional crash after warm up when the "in warmup + state" went away in between doing ESC G and getting the + extended status message. + 2000-03-02 Code cleanup, disabled ZOOM until I have time to + deal with all the side effects. + 2000-03-01 More D1 fixes. In the future I have to come up with + a more elegant solution to destinguish between different + function levels. The level > n does not work anymore with + D1. + Added support for "set threshold" and "set zoom". + 2000-02-23 First stab at level D1 support, also added a test + for valid "set halftone" command to enable OPT_HALFTONE + 2000-02-21 Check for "warming up" in after sane_start. This is + IMHO a horrible hack, but that's the only way without + a major redesign that will work. (KHK) + 2000-02-20 Added some cleanup on error conditions in attach() + Use new sanei_config_read() instead of fgets() for + compatibility with OS/2 (Yuri Dario) + 2000-02-19 Changed some "int" to "size_t" types + Removed "Preview Resolution" + Implemented resolution list as WORD_LIST instead of + a RANGE (KHK) + 2000-02-11 Default scan source is always "Flatbed", regardless + of installed options. Corrected some typos. (KHK) + 2000-02-03 Gamma curves now coupled with gamma correction menu. + Only when "User defined" is selected are the curves + selected. (Dave Hill) + Renamed "Contrast" to "Gamma Correction" (KHK) + 2000-02-02 "Brown Paper Bag Release" Put the USB fix finally + into the CVS repository. + 2000-02-01 Fixed problem with USB scanner not being recognized + because of hte changes to attach a few days ago. (KHK) + 2000-01-29 fixed core dump with xscanimage by moving the gamma + curves to the standard interface (no longer advanced) + Removed pragma pack() from source code to make it + easier to compile on non-gcc compilers (KHK) + 2000-01-26 fixed problem with resolution selection when using the + resolution list in xsane (KHK) + 2000-01-25 moved the section where the device name is assigned + in attach. This avoids the core dump of frontend + applications when no scanner is found (Dave Hill) + 2000-01-24 reorganization of SCSI related "helper" functions + started support for user defined color correction - + this is not yet available via the UI (Christian Bucher) + 2000-01-24 Removed C++ style comments '//' (KHK) +*/ + + +/* #define TEST_IOCTL */ + +/* DON'T CHANGE THE NEXT LINE ! */ +/* #undef FORCE_COLOR_SHUFFLE */ + + +#ifdef _AIX +#include /* MUST come first for AIX! */ +#endif + +/* --------------------- SANE INTERNATIONALISATION ------------------ */ + +#ifndef SANE_I18N +#define SANE_I18N(text) (text) +#endif + +#include "../include/sane/config.h" + +#include + +#include +#include +#include +#include +#include +#include +#include +#include + +#include "../include/sane/sane.h" +#include "../include/sane/saneopts.h" +#include "../include/sane/sanei_scsi.h" + +#include "../include/sane/sanei_usb.h" + +#include "../include/sane/sanei_pio.h" + +#define BACKEND_NAME epson +#include "../include/sane/sanei_backend.h" + +#include "../include/sane/sanei_config.h" + +#include "epson.h" +#include "epson_scsi.h" +#include "epson_usb.h" + +#define EPSON_CONFIG_FILE "epson.conf" + +#ifndef PATH_MAX +#define PATH_MAX (1024) +#endif + +#define walloc(x) (x *)malloc(sizeof(x)) +#define walloca(x) (x *)alloca(sizeof(x)) + +#ifndef XtNumber +#define XtNumber(x) ( sizeof(x)/ sizeof(x[0]) ) +#define XtOffset(p_type,field) ((size_t)&(((p_type)NULL)->field)) +#define XtOffsetOf(s_type,field) XtOffset(s_type*,field) +#endif + +#define NUM_OF_HEX_ELEMENTS (16) /* number of hex numbers per line for data dump */ +#define DEVICE_NAME_LEN (16) /* length of device name in extended status */ + +/* NOTE: you can find these codes with "man ascii". */ +#define STX 0x02 +#define ACK 0x06 +#define NAK 0x15 +#define CAN 0x18 +#define ESC 0x1B +#define PF 0x19 + +#define S_ACK "\006" +#define S_CAN "\030" + +#define STATUS_FER 0x80 /* fatal error */ +#define STATUS_AREA_END 0x20 /* area end */ +#define STATUS_OPTION 0x10 /* option installed */ + +#define EXT_STATUS_FER 0x80 /* fatal error */ +#define EXT_STATUS_FBF 0x40 /* flat bed scanner */ +#define EXT_STATUS_WU 0x02 /* warming up */ +#define EXT_STATUS_PB 0x01 /* scanner has a push button */ + +#define EXT_STATUS_IST 0x80 /* option detected */ +#define EXT_STATUS_EN 0x40 /* option enabled */ +#define EXT_STATUS_ERR 0x20 /* other error */ +#define EXT_STATUS_PE 0x08 /* no paper */ +#define EXT_STATUS_PJ 0x04 /* paper jam */ +#define EXT_STATUS_OPN 0x02 /* cover open */ + +#define EPSON_LEVEL_A1 0 +#define EPSON_LEVEL_A2 1 +#define EPSON_LEVEL_B1 2 +#define EPSON_LEVEL_B2 3 +#define EPSON_LEVEL_B3 4 +#define EPSON_LEVEL_B4 5 +#define EPSON_LEVEL_B5 6 +#define EPSON_LEVEL_B6 7 +#define EPSON_LEVEL_B7 8 +#define EPSON_LEVEL_B8 9 +#define EPSON_LEVEL_F5 10 +#define EPSON_LEVEL_D1 11 +#define EPSON_LEVEL_D7 12 +#define EPSON_LEVEL_D8 13 + +/* there is also a function level "A5", which I'm igoring here until somebody can + convince me that this is still needed.

Dairiki + +Here is a new HP backend. It's name is, appropriately, ``newhp''. + +It is still in the pre-alpha stages but mostly works on my ScanJet 5P. +It is completely untested on other scanners, but might hopefully work +on ScanJet models IIp, IIc, IIcx, 3p, 3c, 4c, 4p, and 5p. + +I've only really tested this with xscanimage. + +Some features included in this backend which aren't in the old +HP driver are: + + Support for custom tonemaps (gamma-maps). For some reason I + can't get the 10-bit tonemaps working with my 5p, so for you + only get a single tonemap (it still works in color mode, but + you don't get individual control over each R/G/B channel.) + + You can enable the scanjets "Auto Threshold" mode when scanning + line-art. I can't notice that it does much though.... + + Added an option to control the scan speed. + + Added an option to select the dither pattern used in half-tone mode. + I don't think that custom dither patterns are working correctly, + and in any case, with the current front-ends, there is no convenient + way to set a custom dither pattern.... + + Added an option to select the color correction matrixes. + This also seems to be flaky.
