How can I change the font or background color of my PDF e-book. I use Adobe reader v10 and it has no default option to change this.
Is there a way to edit the e-book to change the font or background color?
Taken from here:
I don't know if the version of Adobe Reader matters or not (or if it matches what you have).
You could also consider using a different PDF view. I personally perfer SumatraPDF. It has a settings.txt file that you can edit to customize the text, background etc., which can be accessed via
Advanced Options (options your default text editor for txt files).
NOTE: I am using SumatraPDF v2.4
To answer the second part of your question: it is possible but not trivial to change the font and the background colour of a PDF file.
I have successfully done such edits on existing PDF files using pdfedit.
