Scanning Options
is set to black-and-white, single-sided, resolution 300 dpi, and 30-50%
brightness. Set Input Page Size
to
Letter R, Output Page Size
to
Letter, and Orientation
to
Same as Original.
For each group,
scan01.pdf
if you have more
than 9 batches).
scanN.pdf
, execute
gs -sDEVICE=pbmraw -r300 -o scanN%03d.pbm scanN.pdf
scanxyyy.pbm
for each student, where
x
is whatever replaced N.
[Note: we have had problems with having different batches
come out with different orientations. This can be checked by viewing the
first page of each scanN.pdf
and checking
that the answers appear on the top. If that is not the case, ask Joel for
help.]
Now execute
ls scan*.pbm > inputlist
flipitcw
scanxyyyflip.pbm
for each student,
which are rotated so that the answer form on the right.
ls scan*flip.pbm > inputlist
gthumb `head -1 inputlist`
, and make
sure the answers are on the right side of the page. [Note those are accent
graves, not apostrophies].
If this is not
correct, remove any flipped files (
rm *flip*.pbm
, remake inputlist with
ls scan*.pbm > inputlist
, and then
if necessary execute the
the two commands for flipitcw above, but with
cw replaced by 180 or ccw, to rotate by 180 degrees or counterclockwise.]
