Hi all I'm looking for advice on which language is going to be the best to use when it comes to being able to open a PDF file and read the content. Specifically what I'm trying to do is create a program that is able to open a PDF file and interact with the 'lines' - for example measure distances on a PDF drawing. eg: PDF X-Change style app. I'm a PHP / Web dev, so I have actually created something similar using the skills I have, which was HTML5 canvas, PHP, jquery, but essentially all I was doing was overlaying a transparent div and tracing the objects and getting my measurements that way, which works fine, but it's too slow... I want to be able to natively select a 'line' in a PDF and then work out details based on that. I know this is a very vague question, but I'm looking for people who have experience in other languages to chime in and I'll research those, I'm pretty good and picking up new languages and learning plus I have the time and resources... I just need some directions if possible. I was thinking Python would be the go, but wanting some advice.
