Command line tips

• making pdfs from images:
  • renaming the files - so that convert gets them in the correct order.
    • for ((i=3;i<=9;i+=1)); do mv $i'.png' '0'$i'.png'; done
  • This is to crop the images.
    • convert '*.png[803x965+429+27]' %02d.png
  • sudo apt-get install gs pdftk sam2p
  • convert pngs to pdfs (convert did not scale the images properly)
    • for ((i=0;i<=3;i+=1)); do sam2p '0'$i'.png' '0'$i'.pdf'; done
  • combine the individual pdfs
    • gs -dNOPAUSE -sDEVICE=pdfwrite -sOUTPUTFILE=combinedpdf.pdf -dBATCH *.pdf
