Hi,
My emailer garbled that. Here it is as an attachment.
Hopefully, this will be better.
Cheers,

Hi,
I finally got around to testing the new escl backend with my HP
OfficeJet 6978.
It does appear to be supported on two ports, one encrypted:
device `escl:https://10.1.40.2:443' is a ESCL HP-OfficeJet-6978 SSL
flatbed scanner
device `escl:http://10.1.40.2:8080' is a ESCL HP-OfficeJet-6978
flatbed scanner
Preview and higher resolution scans are OK.
However, there appears to be something squiffy about the geometry
options. I cannot get a full sheet scan.
This is what I get from scanimage as regards the available options:
Options specific to device `escl:https://10.1.40.2:443':
Scan mode:
--mode Gray|Color [Gray]
Selects the scan mode (e.g., lineart, monochrome, or color).
--resolution 75|100|200|300|600|1200dpi [75]
Sets the resolution of the scanned image.
--preview[=(yes|no)] [no]
Request a preview-quality scan.
--preview-in-gray[=(yes|no)] [no]
Request that all previews are done in monochrome mode. On a
three-pass scanner this cuts down the number of passes to
one and on a
one-pass scanner, it reduces the memory requirements and
scan-time of
the preview.
Geometry:
-l 0..0.0122375pel (in steps of 1.52588e-05) [0.000244141]
Top-left x position of scan area.
-t 0..0.0156708pel (in steps of 1.52588e-05) [0.000534058]
Top-left y position of scan area.
-x 0..0.0119934pel (in steps of 1.52588e-05) [0.0386658]
Width of scan-area.
-y 0..0.0151367pel (in steps of 1.52588e-05) [0.0529785]
Height of scan-area.
Using the current PPA from Rolf as of today, which is probably gonna
be GIT COMMIT 1942C5FD.
Cheers,
Ralph
Hello, Ralf,
Thank you for the feedback and for the log.
I'm working on geometry.
I will propose a patch soon.
Cheers
