+---------------------------
+
+ * changed gamma-data-upload for 3-pass-color-scan

+
+ * 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,

+
+ * added empty routine umax_do_calibration in umax-scsi.c, it shall be called

+ * moved sense-handler from umax.c to umax-scsi.c
+ and added detection for driver-calibration-request
+ sense_handler got a new parameter (void *arg).

+ * 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
+
+ * 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:
+ values: 1-65535, default scan-lines=40, preview-lines=10
+ define the maximum number of lines that are scanned into one buffer
+
+ - force-preview-bit-rgb:
+ values: 0=disabled, 1=enabled, default=0
+ set preview bit in rgb real scan
+
+ - slow-speed, care-about-smearing:
+ values: -1=auto, 0=disabled, 1=enabled, default=-1
+ dangerous options, needed for some scanners
+
+ - calibration-full-ccd:
+ values: -1=auto, 0=disabled, 1=enabled, default=-1
+ do calibration for each pixel of ccd instead of selected image
+
+ - calibration-width-offset:
+ values: -1=disabled, >=0 set value
+ add an offset width to the calculated with for image/ccd
+
+ - calibration-bytes-pixel:
+ values: -1=disabled, 0=not set, 1=1 byte/pixel, 2=x bytes/pixel
+ use # bytes per pixel for calibration
+
+ - invert-shading-data:
+ values: -1=auto, 0=disabled, 1=enabled, default=-1
+ invert shading data before sending it back to the scanner
+
+ - lamp-control-available:
+ values: 0=automatically set by driver - if known, 1=available, default=0
+
+ * updated html-documentation
+
+ * updated sane-umax.man
+
+ * added pre focus options (PowerLook 3000):
+ - FP - fix focus position
+ - FDC - lens calibration in doc position
+ - PF - disable pre focus
+ - LCL - use 0.6/0.0mm holder focus position
+
+ * added #define SANE_I18N(text) text to umax.c. This is to mark the backend
+ specific texts that shall be translated by the frontend
+
+
+build-25 -> build-26
+--------------------
+
+ * added umax.conf option handle-bad-sense-error #
+
+ * added Mirage II as supported scanner
+
+ * added routine umax_set_max_geometry that defines available surface
+ and resolution in dependance of scansource and double optical resolution
+ (before this bugfix the change of dor mode overwrote the settings of
+ scansource and vice versa)
+
+ * added ESCORT Galleria 600S as supported scanner, is an Astra 600S
+
+ * removed if (config_line[len - 1] == '\n')... while reading config file
+
+ * changed some static unsigned int to static int
+
+ * sane_exit does free devlist
+
+ * added some options for Powerlook 3000 - still is not completly supported
+
+
+build-26 -> build-27
+--------------------
+
+ * added Linotype Saphir4 as supported scanner (is a Powerlook III)
+
+ * increased length of vendor, product and version by 1 to make sure the
+ string always ends with '\0'
+
+ * changed default minimum scsi buffer size from 64KB to 32 KB
+
+
+build-27 -> build-28
+--------------------
+
+ * removed "#include <assert.h>" from umax.c, assert() is never called
+
+ * added UMAX Powerlook 3000 as supported scanner
+
+ * bugfix for 3 pass scanning:
+ reposition_scanner is called in sane_start for 2nd and 3rd pass of 3 pass scan
+
+
+ * bugfix for UTA and DOR geometry offsets:
+ - added inquiry_uta_x_off and inquiry_uta_y_off
+ - geometry ranges are defined from xoff..xoff+dx, yoff..yoff+dx now
+ - check_values also does test for this range
+ - removed dev->maxwidth and dev->maxlength, values are calculated in place now
+
+ * bugfix for DOR:
+ - bottom-right edge keeps in position if possible when DOR is switched on
+
+ * bugfix for Astra 600S and 610S color mode:
+ - scale_y is set to 0.5 if y_resolutions is smaller than optical_res/2
+ this does fix the color scan problems for Astra 610S.
+
+ * added Heidelberg Linoscan 1400 "HDM LS4H1S" as supported scanner
+
+
+build-28 -> build-29
+--------------------
+
+ * removed bug in umax_set_max_geomentry: now left y keeps in position when possible
+
+ * rgb bind keeps unchanged when scanmode != color (only gray selection active in this case)
+
+ * in function static int umax_give_scanner(Umax_Device *dev) moved umax_reposition_scanner(dev);
+ to the end of the function
+
+ * set calibration area for astra 2200 to full ccd and calibration_bytespp to 2
+
+ * UC840 does wait in reposition_scanner until scan head stops moving
+
+ * set minimum resolution to 5 (was 1 before what could make problems)
+
+
+build-29 -> build-30
+--------------------
+
+ * added EDGE KTX-9600US as supported scanner
+
+ * Changing scansource does not change lower left selection edge
+ if not necessary
+
+
+build-30 -> build-31 (sane-1.0.6)
+---------------------------------
+
+ * sane-umax.man uses @LIBDIR@ and @CONFIGFIR@
+
+ * changed automatic calibration_width_offset marker from -1 to -99999
+
+ * changed
+ dev->calibration_area to 1 and
+ calibration_width_offset to -1 and
+ inquiry_max_calibration_data_lines to 66
+ for UMAX Supervista S-12, LinoHell Office and LinHell JADE
+
+
+build-31 -> build-32 (sane-1.0.7)
+---------------------------------
+
+ * added Nikon AX-110 as supported scanner (Vista S6E)
+
+ * added umax.conf option "gamma-lsb-padded" with options:
+ -1 = auto
+ 0 = inactive (msb padded)
+ 1 = active (lsb padded)
+ activated for astra 1220s, internal 12 bit gamma correction does work now
+
+
+build-32 -> build-33
+--------------------
+
+ * added USB support for Astra 2200
+ thanks to Frank Zago <fzago@greshamstorage.com>
+ for creating umax-usb.c and suggesting several changes to umax.c
+
+ * added umax.conf option "connection-type", values: 1=scsi, 2=usb
+
+ * added umax.conf device selection "usb 0x1606 0x0230" (usb vendor_id product_id)
+
+ * removed #ifdef HAVE_SANEI_IPC parts (SANEI_IPC was never defined)
+
+
+build-33 -> build-34 (sane-backends-1.0.8)
+--------------------
+
+ * removed bug in reader_process / umax_queue_read_image_data:
+ - the integer value that keeps the length information is kept valid
+ as long a queued scsi command is still running now
+ - when the scsi command returns with less data than requested
+ then the routine does handle this correct now
+ (before the routine handled this as if the requested amount of
+ data was returned)
+
+ * backend waits until scanhead has repositioned after scan for UMAX UC1260
+
+ * y_dpi quanitsation is set to 5 (same as x_dpi quantisation - was 1)
+
+
+build-34 -> build-35
+--------------------
+
+ * changed ID string "LS4H1S " to "LS4H1S " (remove one space)
+
+ * activated lamp control for Astra 1220S V1.5
+
+
+build-35 -> build-36
+--------------------
+
+ * added PowerLook 2100XL as supported scanner
+
+ * settings for PowerLook 2100XL:
+ calibration_width_offest = 52
+ (calibration_bytespp = 2, default)
+ (calibration area = image, default)
+
+ * force_quality_calibration defined for PowerLook 2100XL:
+ (normal calibration mode expects different calibration_width_offsets
+ for PowerLook 2100XL, so it is not possible to calculate the correct
+ number of calibration pixels in normal calibration mode)
+ - disable quality calibration option for frontend
+ - always set quality calibration bit when scanning
+
+ * changes for exposure times:
+ - Inquiry does print correct maximum value now
+ - changed variable type from SANE_FIXED to SANE_INT
+ - exposure times setting for colormode does work correct now
+ - as default there is only one common setting for exposure times in rgb mode,
+ added umax.conf option exposure-time-rgb-bind to enable different settings
+ for each color
+ - added option select-calibration-exposure-time, disabled by default.
+ if disabled then the calibration expousre times are the same as the scan exposure times
+
+ * added UMAX PS-2400X as supported device
+
+ * added batch scanning support:
+ Options:
+ --batch-scan-start: calibration, scan, scanhead is not moved into home position
+ --batch-scan-loop: no calibration, scan, scanhead is not moved into home position
+ --batch-scan-end: no calibration, scan, scanhead is moved into home position
+ --batch-next-tl-y: defines the y start position of the bext batch scan
+
+ - calibration for batch scan needs a different offset and always is done for full ccd.
+ PowerLook 2100XL: calibration_width_offset_batch = 1052
+ Powerlook III: calibration_width_offset_batch = 828
+
+
+build-36 -> build-37
+--------------------
+
+ * added Linotype Hell SAPHIR3 as supported scanner
+
+ * if batch-next-tl-y is not set then the backend uses br_y
+
+
+build-37 -> build-38 (sane-backends-1.0.9)
+--------------------
+
+ * added Power Look 2000 as supported scanner
+
+
+build-38 -> build-39 (sane-backends-1.0.10)
+--------------------
+
+ * Power Look 2000: corrected wrong calibration-width-offset from 52 to 22
+ and added calibration-width-offset-batch to 24
+
+ * initialized some global pointers and num_devices in sane_init
+
+ * replaced fork() by thread for OS2
+
+build-39 -> build-40 (sane-backends-1.0.12)
+--------------------
+
+ * UC630: dev->pause_after_reposition = 0
+
+
+build-40 -> build-41 (sane-backends-1.0.13)
+--------------------
+
+ * Astra 2200 SU via USB connection: quality calibration is reset and not selectable
+
+
+build-41 -> build-42
+--------------------
+
+ * replaced fork() routines by sanei_thread routines
+
+ * added call sanei_scsi_req_flush_all(); to do_cancel - in threaded case this is not done when reader_process is cancled
+
+ * in reader_process: marked freed scsi buffers as freed(NULL). This is necessary when reader_process is run as thread!
+
+ * Backend is compatible to Mac OS-X now.
+
+
+build-42 -> build-43
+--------------------
+
+ * DOR mode does test for non negative upper_left_x values, set to 0 if negative
+
+
+build-43 -> build-44
+--------------------
+
+ * the sense_hanlder stores the sense data in buffer[0] when valid sense data is avialable
+
+ * do_calibration:
+ - corrected bug in reading calibration width from scanner (added /bytespp)
+ - when additional request sense is not called then the buffer is not erased,
+ the sense data from the sense_handler is used
+ - when additional request sense is called then the buffer is erased at first
+
+build-44 -> build-45
+--------------------
+
+ * added defualt options for Linotype Opal2
+ * changed bug in highlight-blue function (using green value)
+
