  • Tweaked Crossword Scanning

    In what’s surely a change intended to better meet the needs of their customers, the newspaper changed the crossword layout just a little teeny bit, so my previous script needed a tweak:

    #!/bin/bash
    echo Scanning...
    scanimage --mode Gray --opt_emulategray=yes --resolution 300 -l 5 -t 0 -x 105 -y 195 --format=pnm > /tmp/scan.pnm
    echo Converting...
    convert /tmp/scan.pnm -level 45%,60% -resize 2400x3150 +repage -unsharp 0 /tmp/trim.png
    convert -density 300 -size 2550x3300 canvas:white /tmp/trim.png -gravity center -composite /tmp/page.pdf
    echo Printing...
    lp -n 2 /tmp/page.pdf
    echo Done!
    

    It now spits out two large-print copies, to better meet their actual needs, at least for two of their customers.
