Cut, join, create/edit bookmarks, crop the white edges of the pages, and improve/get slim PDFs. This will not be a problem anymore with the free software listed below.
Very often you want to read comfortably on screen or on eBook reader, the PDFs created for printing: two side or slides of presentations (2 or more slides per page), without zooming or scrolling from side to side. After several fruitless searching I have found a great solution: LaTeX. With the help of 2 different types of PDFs, I show you how to automatically crop them.
The convenience of a good index in printed documents is essential to ensure fast tracking of the desired content, and a rapid overview. In PDF files, however, the situation is different, they are always too slow and uncomfortable, not to mention of their consultation in the ebook reader. So the bookmarks become an unavoidable choice, below I describe how to insert them with LaTeX or with a friendly GUI editor.
A big gap of my eBook reader, the Asus DR900, is the maximum page zoom fixed to 200%. Generally the 200% works fine for most PDF file, but when I try to read PDF that includes double pages or document in A4 with A3 pages, the reading become very difficult. So I wrote a little bash script called set-uniform-pagination.sh that halves the pages exceeding the horizontal dimension of the first.
It is a electronic gadget little widespread, but with some hint it might be an optimal solution to read comfortably digital documents, without using printer or staying for long time in front at the monitor.
I own an ebook reader for almost a year, in detail an Asus DR900. It is a problematic product with some imperfections that lets me consult documents, saving me from photocopies and from eye strain.
