all umax_... functions are made static
* removed umax-emergency-routine for SANE
* made program-flow (esp. with do_canel) SANE-specific
* fixed missing 3-pass parts
* made scanmodes, sources, analog gamma, gamma download, negative,
quality calibration, highlight, shadow only selectable if they are
available
* calibration-mode selectable in advanced options if available
* warmup selectable if available
* changed umax-scsi.c like described from Gordon Matzigkeit
in his diff/patch-file from 21.06.97 so that the umax-backend
should compile on non-linux-systems now - thanks!
* split highlight and shadow in R, G and B for color-mode.
* reset adf and uta flag when not used (in sane_start)
* added possibilty to change calibration-mode if available
* added send_halftone_pattern to umax-scsi.c
* changed umax-scsi.c like described from Gordon Matzigkeit
in his diff/patch-file from 21.06.97 so that the umax-backend
should compile on non-linux-systems now - thanks
* added support for each color (R,G,B) for highlight and shadow
* added "Astra 1200S" and "UC840" as supported
* added bad bugfix for preview-problem with S6E
(in umax-scsi.c function start_scan)
* moved resolution-check from check_values to bound_scanarea,
now no floatingpoint-exception will occur if no resolution is given!
* changed range-check for width and height
* removed bug in set_window for three-pass-rgb-mode
-selected wrong buffer for some green and blue options
-scanmode now is greyscale instead of rgb
* changed start_scan(us) to better use with wid-list
and added missing 3 wid-bytes in scan.cmd
* removed parameter color in three_pass_function_headers,
the color ist taken from us->three_pass_color now.
sane-0.63/0.64/0.65 -> 0.66
---------------------------
* changed gamma-data-upload for 3-pass-color-scan
* corrected wrong calculation for highlight and shadow
selection for rgb-values
* changed gamma data to use 8 bit (256 bytes) or 10 bit (1024 bytes)
* included 10/30 bits per pixel mode
* changed bug in sane_exit (free()) that sometimes made a
segmentation-fault
* made patches runtime-selectable
* changed set_window_command to support 30 bits per pixel
* changed send_gamma_data to support three_pass_gamma and 10/30 bpp
* changed row_len in umax_bound_scanarea to 10/30 bit mode
* added halftone-support for ug630, uc630 and uc840,
but I don't know if all values are ok!
* changed CBHS-50-range to 78-178 (from 103-153)
* changed rangecheck for highlight and shadow

* made patches runtime-selectable
sane-0.66 -> 0.67
-----------------
* removed bug in sane_start: ADF and UTA flags have not been set correct
* removed bug in init_options: value range for 10 gamma-input-bits corrected
* made custom gamma available for lineart and halftone for nonlinear effects
* added Vista-T630 as supported scanner
* removed test_warmup in wait_scanner because adaptec 1542 has problems
with request_sense-command in test_warmup
it was only used for printing a message, so it was not important.
* if a scanner has a full inquiry-block but is not known to be supported,
the driver will print a warning and continue instead of aborting,
option --continue (on umax-cli) will suppress the warning!
* changed ugly definition
char gamma[x] -> char *gamma; gamma=alloca(x);
* removed bug (wrong length for 10 bit-gamma) in send_gamma_data
* changed all buffer-definitions to unsigned char and insterted
type conversions, so there are no more warnings because of
typemismatches.

sane-0.67 -> 0.68
-----------------
* changed open config to fp = sanei_config_open(UMAX_CONFIG_FILE)

and changed set_inquiry_length-offset from 5 to 4
* added calib_lines to structure US and added it to
set_window - command in umax-scsi.c
* changed in umax-scsi.c routine identify_scanner:
vendor and product is tested for each model instead of
vendor=="UMAX " and only model tested!
Because of that the format of scanner_str has changed
from product,product,...
to vendor,product, vendor,product,...
* added support for Linotype Hell Jade (LinoHell Office)
* added empty routine umax_do_calibration in umax-scsi.c, it shall be called
after umax_start_scan!

and added detection for driver-calibration-request
sense_handler got a new parameter (void *arg).

* added routine that corrects wrong inquiry-data from
Astra 600S and Astra 610S
* added test and selection for do_color_ordering in check_values
* changed __sun-code in umax_wait_scanner because the scsi-driver
answers with IOERROR instead of DEVICE_BUSY
(this is only a bugfix for a little time)

* added umax_start_scan at the end of calibration by driver,
the scanner does not hang any more if quality calibration is enabled!
There must'nt be a "wait_scanner" in calibration by driver routine!!!
* added usage of driver internal values for calibration by driver if
the scanner does not give back the informations about the shading data:
width = dev->width * dev->inquiry_optical_res ( * 3 in RGB-mode )

if (..) {...}
=>
if (..)
{
...
}
* removed unnecessary SHADING_TYPE-handling routines for UMAX S-6E, UMAX S-6EG and Vista-S6E
* scsi buffer is only reallocated when size has changed
build-18 -> build-19
--------------------
* added UMAX PowerLook III as supported scanner
* added EPSON Perfection600 as supported scanner (is a Astra 1200S)
* type of option 0 (Option numbers) is set to SANE_TYPE_INT now (undefined before)
* removed bug that mixed 12 bit and 14/16 bit gamma table when 14 or 16 bit are supported
and changed value range of grey custom gamma table:
- maximum output value is 255 for 8 bits/pixel
- maximum output value is 65535 for 9-16 bits/pixel
the custom gamma table does work now with 9-16 bits/pixel output mode
* added routine that reverses bit order in lineart mode when scanner sends LSB first in lineart
build-19 -> build-20
--------------------
* added variable calibration_width_offset, Mirage D-16L offset of 308 is defined there
and added offset of 28 for PowerLook III
* umax_do_calibration: guessed calibration data vaules use 2 bytes/color if scanner
supports gamma input bit depth supports 2 bytes/color
* calibration by driver now does work for PowerLook III
* added function umax_set_rgb_bind() that sets the sensitivity of some options
that make available different settings for RGB. This function now is called
when scanmode is selected.
* changed some int to unsigned int
* made dev->pause_after_reposition = -1; as default, so as default sane-umax does not wait
any more while the scanhead is moving back - this may break the support of some scanners
so it may have to be changed (dev->pause_after_reposition = 0;) for some scanners.
reported to work for:
- Supervista S12
- PowerLook III
- Astra 2200
build-20 -> build-21 (sane-1.0.3)
---------------------------------
* Added Linotype "JADE" as supported scanner
* Removed bug in sane_close that caused segfault when
sane_close was called twice with the same scanner handle
build-21 -> build-22
--------------------
* replaced fgets() by sanei_config_read()
* added command queueing for scsi read commands
- removed WAIT_SCANNER scsi command call after read command
- the additional buffers are allocated in the reader process
- the number of buffers can be defined in umax.conf
with option scsi-maxqueue [1..8] default:2
(did some tests with Supervista S12 and PowerLook III
on the same scsi controller (ncr53c810):
command queueing works, it is possible to start
both scanners at the same time. The scanner with the
higher scsi-ID (=priority) does scan without stops,
the other scanner has to wait long time between the
scsi-read commands, it also is possible to give
bothe scanners different scsi command queueing depth).
* prepared replacement of pipe by sanei_ipc_* routines
* added routines umax_get_lamp_status and umax_set_lamp_status
* updated inquiry output (new bits from powerlook scsi protocol 1.0 X101)
* added new (powerlook scsi protocol 1.0 X101) window descriptor block entries to umax-scsidef.h
* added button protocol (3 buttons, from powerlook scsi protocol 1.0 X101)
* added button "lamp off" to turn off scanner lamp
(this option may be remoeved again in later version, may be
it will be replaced by an autmatic lamp turn off function)
* added options to umax.conf
lamp-off-at-exit [01] default:0
lamp-off-time [10..720] (in minutes) default:30
* if lamp_off_at_exit == 1 and lamp_control_available == 1
the scanner lamp is turned off in sane_close
* renamed umax-scanner.h and umax-"scannername".h to umax*.c
because these files create data code
build-22 -> build-23
--------------------
* scsi commands set/get lamp control are send with a command length of
10 bytes instead of 6 bytes and control bit #7 is in byte 0x03
and not in byte 0x04 (it is described incorrect in the umax doc)
* enabled lamp control for Astra 2200
* removed umax.conf options lamp-off-at-exit and lamp-off-time
* added frontend option lamp-off-at-exit
* added frontend option lamp-on
* forcing calibration_bytespp = 1 for Astra 2200 - quality calibration does work now
* for Astra 2200 selection for different x/y resolutions is disabled
build-23 -> build-24 (sane-1.0.4)
--------------------
* forcing calibration_bytespp = 1 for Astra 2100S
* Added Astra 2100S as supported scanner
* enabled lamp control for Astra 2100S (don`t know if this works, is a test)
* Added warning in sane_control_option if option could not be set
build-24 -> build-25
--------------------
* dev->lamp_control_available is preset to 0
* dev is erased (0) after it is allocated
* added special options for PowerLook 3000:
- calibration is done for each CCD pixel
- calibration_bytespp is set to 1
the scanner still is not listed as supported scanner because
the changes are not tested
* added options that are read from umax.conf:
- execute-request-sense:
values: 0=disabled, 1=enabled, default=0
If set to 1 umax_do_request_sense is called in umax_do_calibration.
This can hang the system (but has been enabled until this version)
- scsi-buffer-size-min, scsi-buffer-size-max:
values: 4096-1048576, default min=65536, max=131072
- scan-lines, preview-lines:
