To download magazine from issuu.com when the download option has been disabled. in practice the script doesn't actually download the pdf, but rather download the images of the pages of the flash object and then combines those into a pdf

issuu_downloader.rb

require 'mechanize'
require 'prawn'
=begin
running from terminal to download any pdf from issuu.com, given
- magazine name
- page count
- document-id
=end

prompt = "> "

puts "What is the name of the magazine you'd like to download from issuu.com? ps: this will be the name of your pdf file\n"
print prompt
magazine_name = gets.chomp


puts "How many pages does it have?\n ie 104\n"
print prompt
page_number = gets.chomp

puts "document Id? \n to get the 'document-id' inspect page in chrome,\n search for document-id and paste here,\n ie 140601160255-3a4c0f75ec731801ef369f5000f03104\n"
print prompt
document_id = gets.chomp

for i in 1..page_number.to_i
  print "downloading\tpage n #{i}\n"
  agent = Mechanize.new
  link = "http://image.issuu.com/#{document_id.to_s}/jpg/page_#{i.to_s}.jpg"
  agent.get(link).save "page_#{i.to_s}.jpg"
  print "downloaded\tpage n #{i}\n"
end

print "images from 1 to #{page_number.to_s} downloaded as jpg\n"

########to combine all images into a pdf

Prawn::Document.generate("#{magazine_name}.pdf", :page_layout => :portrait) do |pdf|

  for i in 1..page_number.to_i
      pdf.image "page_#{i.to_s}.jpg", :at => [0,750], :width => 530
      pdf.start_new_page
  end#end of loop
end

print "images from 1 to #{page_number.to_s} combined into pdf \n"

########to delete all images, once pdf as been created, to clean up a bit
for i in 1..page_number.to_i
  File.delete("page_#{i.to_s}.jpg")
end#end of prawn

print "images from 1 to #{page_number.to_s} deleted \n"
# print "your pdf #{magazine_name}.pdf is in: \n #{Dir.pwd}"

i'm new to this . can anyone explain where to paste this code ?

Sorry just saw this now, save it as a .rb file, and run it from terminal on your computer.
(you may need to install the mechanize and prawn gem if you don't have them already...)

hope this helps

is it possible to make a drop gui with a link, as well to make just a jpg to pdf converter, why am I asking because I have downloaded some jpg before.

there are no results when I search for documentId

use https://issuu.pdf-downloader.com/

use https://issuu.pdf-downloader.com/

The quality of the PDF document is not good enough using https://issuu.pdf-downloader.com/

The document-id doesn't seem to show up on the inspect page anymore

The document-id doesn't seem to show up on the inspect page anymore

The script was written 9 years ago, I suspect that the structure of the issue page might have changed since then.

Haha that's a very good point

Lol yeah. If it’s helpful this is a blogpost I wrote a while back that walks through how I got to that initial script https://pietrop.github.io/issuu.html
