Scanning a Cover Page with Answers Along the Short Edge, Version 1

• Check first that the 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,

• Set the paper guides to 8.5 inches. Feed into the scanner face up, answer form entering first. The side rails should be not quite tight, but close, to keep the forms well aligned.
• scan and send to your email.

• Save the emails in the directory in which you will do the grading, with names in a sequence such as scanN.pdf. Keep the number of characters in N constant (so you might start with scan01.pdf if you have more than 9 batches).
• For each emailed file scanN.pdf, execute
  gs -sDEVICE=pbmraw -r300 -o scanN%03d.pbm scanN.pdf
  [Note: this will work on physlinux2 and other linux machines (shell), but not on the Suns. ]

[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
  This will create files scanxyyyflip.pbm for each student, which are rotated so that the answer form on the right.
• ls scan*flip.pbm > inputlist
• [ inputlist has the names of the files which will be read for grading. If you wish to check, Look at one with 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.]
