PDFlib Text Extraction Toolkit (TET) Manual

oot :to => "home#demo"
> Edit app/controllers/home_controller.rb as follows and insert TET code for extracting
PDF contents. As a starting point you can use the code in the extractor-rails.rb sample:
class HomeController < ApplicationController
def demo
require "TET"
begin
p = TET.new
doc = tet.open_document(infilename, docoptlist)
...TET application code, see extractor-rails.rb...
...
# and finally show the retrieved text
send_data text, :type => "text/plain", :disposition => "inline"
rescue TETException => pe
# error handling
end
end
end
> In order to test your installation start the WEBrick server with the command
$ rails server
and point your browser to http://0.0.0.0:3000. The text extracted from the PDF document
will be displayed in the browser.
Local TET installation. If you want to use TET only with Ruby on Rails, but cannot install
it globally for general use with Ruby, you can install TET locally in the vendors directory
within the Rails tree. This is particularly useful if you do not have permission to install
Ruby extensions for general use, but want to work with TET in Rails nevertheless.
