PDF generator
Posted: Mon Nov 24, 2014 9:05 am
Does anyone have any experience or know of any resources that would help us develop a PDF generator?
Some background: Our devices output a 'log' via various methods that gives a pass/fail report. Some customers are finding the machine operators are opening this file (which is just a .txt file) and editing it to 'hide' their mistakes.
We are thinking that if we can generate it as a PDF this will be more secure as they aren't as easy to edit. Of course someone who knows what they are doing could manage it but hopefully your average man on the street would struggle.
All the references I can find for PDF generators are PC based and the techniques they describe look very difficult to implement on a micro, mainly due to the lack of RAM.
