Thanks for looking at it...

Ah, now I remember why the script does not use the routines from the
"add" package. Right now the add package unconditionally adds all pages
of a tiff, while the script handles the input image on a page by page
basis.

This will not make a difference for you if you are simply using single
page tiffs, but does mean that your code is not quite correct either
unfortunately :)

I'll need to properly fix this somehow so that the script works with
simplex projects with both simplex and duplex scans.

/me opens a ticket to not forget.

Issue #83.

Yes it is a simplex document.
Unfortunately the patch you sent threw this:
[tkovacs@sunspot new]$ ./sdaps-recognize.py tenq tenq_scan.tif
TIFFOpen: tenq/../DUMMY: No such file or directory.

AssertionError: The image surface could not be created! Broken or non

after some tinkering I resorted to importing add_image from sdaps.add
which does the correct magic.

$ diff ../sdaps-1.1.10/custom-scripts/sdaps-recognize.py sdaps
-recognize.py
31a32

from sdaps.add import add_image

<     img.filename = os.path.relpath(os.path.abspath(tiff),
survey.survey_dir)

     add_image(survey, images.pop(0)[0], survey.defs.duplex)

Hi,

hm, interesting. My guess would be that you have a simplex document?
Probably never tested the script in that case.

Short explanation. SDAPS basically assumes internally that all
surveys
are printed and scanned in duplex mode. To handle simplex mode the
"sdaps add" command inserts a special dummy page so that exactly this
failure does not happen.

If you scanned in simplex mode then apply the attached patch. If you
scanned in duplex mode, then just run the second add_image there
unconditionally instead.
