Re #320.
Some scanners (notably the Mustek 1248UB) doesn't like receiving a
STOP scan command when it is not scanning. Flag prevents it my making
sure that START/STOP commands are only ever paired up.
- add pixel_x0 to GT68xx_Params to keep used pixel_x0
- use scan's pixel_x0 and calibration one to compute offset in
calibration data
- use final scan width for per scan calibration
- compute and use offset when copying from calibration data
- GT68xx_Scanner is extended to hold calibration data for all
resolutions
- gt68xx_sheet_fed_calibrate loops over all resolution and color
mode, and stores result in scanner struct
- calibrators are created from stored data before each scan
seems to be the same as 4 X, it just doesn't have buttons. Cleanup of .desc
file. Fixed gain setting. Mustek ScanExpress A3 USB 600 dpi color scanning works
now.
user report for the Visioneer OneTouch 7300. Updated .desc. Moved check for
stable lamp to its own function. Mustek ScanExpress A3 USB: Use CIS
calibration. Use lamp warmup. Fixed CCD on GT6801 scanning (color scanning was
broken due to a change in motormode_2.
Calibration and exposure uses a broader spectrum now. Expsoure
limit is increased to 50 loops. Genius Vivid 4x is reported to
work so the UNTESTED label is removed now. Visioneer 7300 is
reported to work so the UNTESTED label is removed now. Genius
ColorPage Vivid 1200XE: Removed UNTESTED label. Fixed
resolutions. Adjusted margins. Fixed color order. Fixed
linedistance. Adjusted AFE. Mustek ScanExpress 1248 UB: Fixed
margins. Adjusted AFE. Adjusted exposure. Adjusted
gamma. Changed status to "complete". Mustek BearPaw 2400 CU
Plus: Adsusted exposure and AFE parameters. Hopefully stripes
and similar trouble are gone now. Mustek BearPaw 1200 CU:
Increased exposure to avoid vertical lines. Updated manual page.
settings. Calibration is not completely ok yet, however. Code cleanup for
setup_scan (only one function for all chipsets). Simplified line mode/pixel
mode setting Updated TODO. Mustek BearPaw 2448 TA Plus is now only "basic". Too
much trouble for "good". Removed option "fast preview". By default for preview
mode 8 bits/pixel are used. Fixed indentation. Full scan really scans from y=0
on gt6816 scanners now.
as that resolution doesn't work. Make sure that the lamp of the Mustek A3 USB
gets warmed up. It's a CIS scanner with a lamp. That code is untested. Full scan
starts scanning from the start position of the white strip now. Added detection
for Genius Vivid 1200 EX. Fixed product id of Mustek BearPaw 2448 TA Plus. Other
minor updates.
coarse calibration. Adjusted internal gamma correction. CCD scanners use
color mode for coarse+quality cal now. Preview isn't always in 8 bit mode now
(can be selected by option). Upper and lower limits for coarse calibration are
unified now. Added options for adjusting gain and offset.
kernel 2.4.21-pre3 containing the 1-endpoint fix. Fixed A3 USB resolution
setting. Updated A3 USB margins (Pedro Morais <morais@inocam.com>). Added
detection of Genius Colorpage Vivid3x. It's unknown if it works. Updated
.desc file. Don't print calib line warnings by default.
control for CCD scanners. Added flag for SE 2400 USB, added some quirks in
gt68xx_gt6801.c. Fixed gt68xx_gt6801 -> lamp control. Adjusted Plustek 1248U
geometry and afe values. CCD gross calibration changed: start with the default
value from module struct. Is faster now for most cases. Only 2.5 mm of
calibration for GT-6801 scanners. Added "afe" option for gt68xx.conf for
selecting default afe values. Removed AFE and exposure SANE options. Added
documentation for afe option in gt68xx.conf. New version: 1.0-35.
table factor option (SANE_CAP_EMULATED). Setup gamma to 2.0 by default. Fixed
(hopefully) sigpipe when cancelling. No geometry quantization anymore (not
necessary). Plustek 1248U: do linemode for every resolution, fix color
correction. Added comments for every Model member in gt68xx_devices. Added
Plustek UT16B and Genius Vivid3x to .desc. Added implementation for inverted
offset for CCD scanners. Added Mustek ScanExpress 2400 USB. Well, at least
it's detected. Added NEW marker to .desc.
