Re: Itextsharp PDF Parsing Font Requirement

Those files contain font metrics (AFM = Adobe Font Metrics). They are 
needed to calculate the dimensions of snippets of text (height, width). 
The 14 AFM files shipped with iTextSharp correspond with the 14 Standard 
Type 1 fonts. These are fonts that any PDF viewer should be able to 
render, hence there is no need to embed these fonts (unless font 
embedding is a requirement, e.g. in the context of PDF/A).

Please download the free ebook "The Best iText Questions on 
StackOverflow" and read the answers to the questions in the section 
about fonts for more info: https://leanpub.com/itext_so

You don't need AFM files to extract text, as most the information you 
need (such as the width of each glyph that is used in the document) is 
stored inside the document. iTextSharp is useful to extract text from a 
PDF, but sometimes it is impossible to extract text in general (no 
matter which tool you're using). For a more elaborate explanation, 
please watch this video: https://www.youtube.com/watch?v=wxGEEv7ibHE
