Hi to all,  
i’m trying to make a pdf parser. This is my code and the script seems to  
work…

require ‘rpdf2txt/parser’  
require ‘rpdf2txt/default\_handler’

parser = Rpdf2txt::Parser.new(File.read(‘filename.pdf’))  
output = File.open(‘prova.txt’, ‘w’)  
handler = Rpdf2txt::SimpleHandler.new(output)  
parser.extract\_text(handler)

The problem is that the file ‘prova.txt’ created is empty. I’ve not  
found documentation about this library so i don’t know what i’m doing  
wrong.  
Can anybody help me??

thanks in advance

Andrea C.

Interesting - this is the very first PDF-Document I’ve seen that uses  
ASCII85 Encoding.

A simple ASCII85 Decoder, anyone?

Andrea: you’ll have to give me some time on this one - I’ll get back  
to you with a patch…

Cheers  
Hannes
