Got that; but how can I designate checkbox coordinate offsets at
_generation_ time? That must be getting output somewhere at the setup
step, so that a recognize knows where to look for checks relative to the
corner crossmarks...

Thanks for the answer on the rotation.
So how can I adjust the box locations immediately after setup_tex to be
at specific locations?
(or how can I designate through a choiceitem directive the coordinate
locations of checkboxes, without necessitating that the latex generate
content that offsets the checkbox to the same location...)
It just does not work the like that. SDAPS is designed to only handle
one specific layout, and there is no code in place to modify the
checkbox locations on the fly.

Evaluation of the corner crossmarks by sdaps can be used to
insure
that the boxes are in positional alignment on the page (by x and
y...); but no barcodes and no small boxes in the corner.
If you really want to, you can. But you really need to make sure
that
all pages are scanned correctly. There are no safeguards in place
once
you disable the barcode reading.
But if you want to, there is even a file that shows how it can be
done.
The steps involved are:
1. Switch to "custom" style.
2. Preload script that implements your "custom" style.
The first part is as simple as putting "style=custom" into the
latex
document. The second step requires a wrapper script that is run
instead
of the normal sdaps executable. It simply loads an implementation
for
the required functions that will be used later and then runs SDAPS
normally.
There is an example "blank.py" in sdaps/sdaps/recognize.py which
just
assume first page and correct rotation.
Note that you may need to grab the git checkout, as the file is not
in
the release tarball.
And separately: can I edit questionnaire.sdaps after project
setup,
to reflect possibly new box locations??
Nope, it is only read once at setup time. I have some (currently
still
private) example that reads a .csv file with checkbox definitions
on
the fly, does a recognize step and outputs the data as XML. It uses
a
custom style which assumes a QR code in the top left corner. (The
form
would be created manually using another method.)
If people are interested, please ping me, and I'll polish it a bit
so
that it can be published.

Subject: Re: [sdaps] Inspection of Page Number and
Orientation...
(#82)
This is sort of related to my previous page orientation
question
(which is not working yet; but let me bring this question to
the
fore...):
In sdaps.cls, there is a comment:
% We unconditionally print this barcode; it is required for the
recognition process...
And sure enough: if I comment out the bar code and attempt a
scan,
checkmarks don't get recognized
(but note that I left the corner crossmarks from the stamp
process
in place...)
My question is: if I feed all my documents to be oriented in a
uniformly consistent way (and perhaps even pass a hint to sdaps
as
to how they are oriented on the feeder?), can I get sdaps to
recognize the checkmarks without the barcode?
An interrelated question: I see in questionnaire.sdaps that
coordinates for the checkboxes get defined during the setup
process.
If I adjust the coordinates in this file, will a subsequent
scan
read from those new locations??
