Pramila,
The text, including the title, is in a compressed stream, which
contains, among many other things, the marking operations:
F1 102.67 Tf
BT
1 0 0 1 970 3353 Tm
(BILL.)Tj
ET
In the best case, all your files are like this, and all (all!) you
have to do is find the page content streams, decompress them, search
them for the title text, then parse all the marking operations
leading up to it in order to really understand the scaling. Also,
you'd need to check the enclosing XObject(s) for a transformation
matrix, and look in the resources to find out which font "F1" is,
if there is more than one font in the document.
In a slightly worse case, some of your titles may be broken up into
individual characters (e.g., "(B) Tj ... (I) Tj ..." etc.), and it will
be difficult to search for "BILL". Have you considered using OCR?

You are right. But visually we can see that there is different sizes for
heading and body of the page.
Actually I want to somehow detect the Font of BILL heading in the page
and then do some processing.
So I was researching and hoping to get some idea, how to do it.
Thanks for your help though.
Thanks,

Well, in that document, there is only one font - Courier. Which
doesn't really tell you anything L.

Hi,
I have some pdf's created from image files. Now I need the different
Fonts used and the font data as well. Like size, font name etc.
My sample pdf is something like the one I attached.
Thanks,

What does it mean to "get a font"? Just the name of the font? The
name in the PDF? The original name? The Postscript name? other?!
Or did you mean the font data??

Hi Everyone,
I want to get the different fonts used in a PDF while extracting text
from it. How do I do this using iText?
Has anyone have any experience with this or has any idea?
