  • testing strikethrough

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
