Version 0.1.38:
Removed changes regarding 12/14 bit support because of SANE
feature freeze for 1.0.4.
The following fixes are in the software compared to the version
prior to the feature freeze:
- refresh UI after a change in the scan mode setting (was not updated
when going from Binary to Gray or vice versa)
- Read values for "line distance" from the scanner instead of using
hardcoded values. This makes sure the backend always uses the correct
values regardless of firmware version.
- Fixed an "off-by-one" error in the color reordering routine that
caused weird artifacts in some instances.

2000-12-03 Version 0.1.38
|
||||||
|
removed changes regarding 12/14 bit support because
|
||||||
|
of SANE feature freeze for 1.0.4. The D1 fix for
|
||||||
|
reading the values from the scanner instead of using
|
||||||
|
hardcoded values and the fix for the off-by-one error
|
||||||
|
in the reorder routine are still in the code base.
|
||||||
|
Also force reload after change of scan mode.
|
||||||
|
