* AUTHORS: Added Karsten Festag as maintainer of microtek2. * backend/mustek.* doc/sane-mustek.man: Update to Mustek backend 1.0-100. Added option fast-preview that tries to use the fastest mode available for preview. This is supported for the 3-pass scanners (was option "preview in gray") and some of the ScanExpress scanners (6000 SP, 12000 SP Plus). Use #include "../include/sane/...". Put option force-wait into mustek.conf (disabled). Removed block mode for Paragon 6000 SP and 8000 SP. Code cleanup. More debug output. Details in backend/mustek.CHANGES. * doc/.cvsignore: Added sane-as6e.5 and sane-nec.5.DEVEL_2_0_BRANCH-1

CHANGES for the SANE Mustek backend
|
||||
|
||||
2000-11-26
|
||||
* Default for "fast preview" is "false" now because this option doesn't work
|
||||
for all SE scanners correctly.
|
||||
* Added more debug output for area_and_windows.
|
||||
* Added more debug output for set_window.
|
||||
* Set minimum tly for 8000SP to 0.
|
||||
* Don't use block mode for Paragon 8000 SP scanners because this breaks
|
||||
color mode with firmware 2.x.
|
||||
|
||||
2000-11-19
|
||||
* Paragon 6000 SP doesn't use block mode any more. It's a bit faster now.
|
||||
* Updated sane-mustek.man concerning buffersize and blocksite.
|
||||
|
||||
2000-11-17
|
||||
* Updated manpage concerning force-wait. Some minor corrections and additions
|
||||
* Added option force-wait to mustek.conf and did some minor changes.
|
||||
|
||||
2000-11-16
|
||||
* With option force_wait set, the backend waits also before sending the
|
||||
inquiry command. This seems to be necessary for the 600 II N.
|
||||
|
||||
2000-11-12
|
||||
* Use SANE_Int, SANE_Bool, SANE_Word for int wherever this seems to
|
||||
be appropriate.
|
||||
* Move macros to mustek.h.
|
||||
* Code cleanup.
|
||||
|
||||
2000-11-11
|
||||
* OPT_GRAY_PREVIEW is now called OPT_FAST_PREVIEW.
|
||||
* For SE scanners use 36/38 dpi color for fast preview.
|
||||
* use include "../include/sane/" instead of "sane/"
|
||||
* go back to old scheme for SE scanners in color mode (faster scans
|
||||
couldn't be reproduced)
|
||||
|
||||
2000-11-10
|
||||
* added more debug output in constrain_value
|
||||
|
||||
2000-11-05
|
||||
* Released backend version 1.0-98.
|
||||
|
||||
2000-11-05
|
||||
* Added support for TAIV for SE 12000 SP. Lamp is turned off while
|
||||
scanning (seems to work for firmware >= 2.00)

||||

maximum amount of data scanned in one block. The buffer size is

|

Option
|
||||
.B strip-height is a global option. If enabled, the Mustek backend
|
||||
waits after each scan until the scan slider reaches its start position.
|
||||
This option may be useful for testing. Default is off (not enabled).
|
||||
.B strip-height
|
||||
is a global option that limits the maximum height of the strip scanned with a
|
||||
single SCSI read command. The height is specified in inches and may contain a
|
||||
fractional part (e.g., 1.5). Setting the strip-height to a small value (one
|
||||
inch, for example) reduces the likelihood of encountering problems with SCSI
|
||||
driver timeouts and/or timeouts with other devices on the same SCSI bus.
|
||||
Unfortunately, it also increases scan times. Thus, if the scanner is the only
|
||||
device on the SCSI bus it is connected to and if it is known that the SCSI
|
||||
driver does not suffer from premature timeouts, it is recommended to increase
|
||||
the strip-height or remove the option completely, which corresponds to an
|
||||
infinite strip height. See sane-scsi(5) on how to avoid problems with SCSI
|
||||
timeouts.

|
||||
.B force-wait
|
||||
is a global option. If set, the backend will wait until the device is ready
|
||||
before sending the inquiry command. Further more the backend will force the
|
||||
scan slider to return to its starting position (not implemented for all
|
||||
scanners). This option may be necessary with the 600 II N or when scanimage is
|
||||
used multiple times (e.g. in scripts). The default is off (not set).
