Geek asks and answers

2 different blocks of text are combined. Can I separate them if I know what 1 is?

I used several pdf → text methods to extract text from PDF documents. For one particular type of PDF I don't have, PyPDF or pdfMiner do a great job of extracting text. However, http://www.convertpdftotext.net/ does this (almost) perfectly.

I found that the pdf I use has transparent text in it, and it merges with other text.

Some examples of text blocks that I return are as follows:

and I found that "ghost text" ALWAYS :
