[sane-devel] ESCL test

[Ralph Little]

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
