Some scripts I wrote to help me in cutting and compressing a bunch of PDFs

pdf_compressor.rb

require 'ruby-progressbar'

files = (1..10).to_a
dir = "./" # DIRECTORY WHERE THE PDFS ARE KEPT (the PDFs have to be named pdf-#.pdf)

progressbar = ProgressBar.create(:format => '%a %bᗧ%i %p%% %t', :progress_mark  => ' ', :remainder_mark => '･', :starting_at => 0, :total => 21)
files.each do |i|
  `pdf2ps pdf-#{i}.pdf pdf-#{i}.ps`
  progressbar.increment
  `ps2pdf pdf-#{i}.ps pdf-compressed-#{i}.pdf`
  progressbar.increment
end

`rm *.ps`
progressbar.increment

pdf_cut.rb

require 'ruby-progressbar'

file = "./some.pdf"
base = File.dirname(file)

pages = [ # PAGES ARRAY - IT INDICATES THE FIRST AND THE LAST PAGE WHERE THE PDF WILL BE CUT
  [17, 283],
  [284, 618],
  [620, 805],
  [806, 952],
  [954, 1113],
  [1114, 1312],
  [1314, 1407],
  [1408, 1496],
  [1498, 1635],
  [1637, 1672]
]

progressbar = ProgressBar.create(:format => '%a %bᗧ%i %p%% %t', :progress_mark  => ' ', :remainder_mark => '･', :starting_at => 0, :total => pages.count)


pages.each_with_index do |p, i|
  `pdftk #{file} cat #{p[0]}-#{p[1]} output #{base}/cut-#{i+1}.pdf`
  progressbar.increment
end
