Hi,
sane-airscan 0.99.30 is now available.
Improvements:
- Added "sane-intent" option. This option hints the scanner on a purpose
of the scan (Document/Photo/Text and Graphic etc).
Although the exact reaction of setting this option is left to discretion
of the scanner firmware, its influence to the resulting image is very
noticeable, so adding this option gives user a chance to tune his or her
device for the best scanning results, depending on a particular image
and scanning purpose.
This option works for both eSCL and WSD, and offers the following
variants (depends on the particular device):
- "*unset*" (don't send option to scanner)
- "Auto" (WSD only)
- "Document"
- "Text and Graphic"
- "Photo"
- "Preview" (eSCL only)
- "3D Object" (eSCL only)
- "Business Card" (eSCL only)
- "Halftone" (WSD only)
Please notice, device may support only some subset of available variants.
The implementation is mostly contributed by Alvin Wong

Fixes:
- WSD: fixed ADF support on Ricoh Aficio MP 201 (Issue #334)
- WSD: fixed ADF duplex on Epson Workforce WF-3520 (Issue #339)
- WSD: fixed serious issues with OKI MC332dn, MC362dn, MB471 (Issue
#198, PR #343).
- WSD: fixed ADF duplex on Brother MFC-9370CDW (Issue #346)
- eSCL: delay between subsequent image load requests (NextDocument
request), initially implemented as a workaround for Brother
MFC-L2710DW appeared to be a speed limiting factor for the very fast
enterprise scanners, like HP Color LaserJet Entrprise Flow MFP X677. So
this delay made a Brother-specific quirk.
