Re: custom script sdap-recognize.py

[Benjamin Berg]

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.
