Hi all,
first, I want to thank Tilman for his effort getting the text from a page
regardless its rotation.
(https://issues.apache.org/jira/browse/PDFBOX-4371).
second, I want to share with you a small application I created using C#. It
uses ITextSharp library and a custom text extraction strategy to get the
text.
Application: here

Class that process text: here

I was trying to port the code to Java and make it work using PDFBox
objects, but so far, it has been not possible to me.
Basically, the magic occurs in method RenderText (Based on other code I
found in a web page I don't remember :( ). It uses vectors (origin is lower
left corner of the page) to determine stuff like if there is a line break,
or if a whitespace must be put between glyphs.
I just hope this code gives you some light to adjust or improve (if you
consider it necessary) text extraction.
Hi, thanks but sorry, but there are several reasons that I can't use it:
1) I don't know itext, 2) I can't use code "found in a web page I don't
remember" (license!), 3) I don't run exe files.
I think our TextStripper code is similar that it uses some algorithms to
decide where to insert blanks, and whether glyphs are on a line or not.
Tilman
That's it.
Thank you.
Best Regards.
