How To Tag Hebrew Files Using PDFBOX - pdf

Hi folks i am trying to tag the Hebrew file which has the english content in the middle ,
I know we can use the Reversed Chars to reverse the order of the word , but how exactly we can reverse the whole line of content by using PDFBox.
Here is the link of the file that i am trying to tag.

I am sharing one more link of the file which is auto tagged by adobe.

Here is the picture of contents of the original page and auto tagged page, Where we can see the "TJ" at the last in the original file will come to top in auto tagged content.
How exactly the Tj places are changing and based on what condition its happening...!
Thanks..

ghostscript extract pages containing a text string

i need to programmatically extract from a multipage pdf, only the pages containing a text string. Is it possible or i need some other tools? I'm working on aix.
thanx in advance
OK firstly Ghostscript doesn't extract pages from PDF files. It creates brand new PDF files whose visual appearance should be the same as the original, but whose content will be different.
There is no way to do this with Ghostscript in a single pass. You could use the txtwrite device to extract the text then grep through the output files for the text you want, note the page numbers and then run another pass to get those pages into new files.
Be aware that extracting text from a PDF file is far from guaranteed to work! That was not the intent of the original PDF format.
Also note that GHostscript currently only allows for handling a single range of pages, First->Last, so if you have a discontinuous set (eg pages 1, 3, 5, 7 etc) then you will have to run this step multiple times.

A Table of Contents Page for a Scanned PDF

I was given some really old but very useful hand-written notes recently and in a bid to preserve them, I had them scanned into a file in the PDF format. What I have is a 35 page PDF but I want to add a contents page at the beginning so that I can use the first page to click my way to a specific topic.
More precisely,
I want a page which says
Topic 1
Topic 2
Topic 3
...
Each one should be linked to a page of my choosing.
I've explored a lot of standard tools out there to help me with this, like LibreOffice, pdftk etc. but the solution does not appear to be in the form of a simple application and a few clicks. My hunch is that this will require a program written in a suitable language. The way I'd want this program to work as follows:
ProgramName Input.pdf CustomTOC.txt
Where CustomTOC.txt could be a simple ASCII table containing two columns, one column being the title and the second column being the page number. The output of this program will be another PDF file which contains one page appended at the beginning of Input.pdf containing a table of contents with hyperlinks to the right pages.
I have managed to solve this problem though I don't think this is the best way to do it. I have written a Python program that accepts two mandatory inputs - the input PDF file and '|' separated ASCII table containing columns and page numbers. A third optional output can be the name of a PDF file which contains the output. If this is not provided then the original input file is rewritten.
How the code works? Uses a system call to 'pdftk' for bursting the PDF file into its constituent pages. Writes a .tex file which contains a \listoffigures command for the first page with the package hyperref ensuring it links to the figures. The later part of the .tex code contains several figure insertion statements where the PDF file corresponding to each page is inserted, providing captions only to those PDFs for which there is an entry in the provided TOC table.
Why the code is not ideal? It relies on too many dependencies. It relies on a system call to the pdftk package, it requires that LaTeX be also installed on the machine with the graphics package. In the current version of the code, the PDFs on each page do have some offset which I am trying to solve using geometry package with custom margin settings. I will try to post the code once this problem is solved.
A more ideal solution. That which does not require LaTeX and can use some PDF library within Python to achieve the same effect. Comments and suggestions welcome!

Parse Body Text from PDF

I have just recently been experimenting with parsing the text data from a PDF document using iTextSharp in a VB2010 app. the document doesn't contain any images or other fancy elements, just text. Ive read some articles and used some code snippets and it looks promising. However, what Ive been trying to do is just parse out the body of each page, minus a header or footer. I haven't found any guidance for that particular function.
Currently using the snippet found here Reading PDF content with itextsharp dll in VB.NET or C# but it parses all text in a page. There's got to be a way to just get the body. Or at least I hope so.
PDFs generally do not contain information about logical structure of contained text.
So there are no headers, footers, body, paragraphs and anything like this in a PDF. There is only bunch of operations like "draw this glyph here", "move to this position and draw that group of glyphs there". I wrote glyph and not character because PDFs are not required to contain readable text. Only visual appearance required to be specified.
One exception is Tagged PDF but most of PDFs in the wild are not tagged.
Given all of the above you are probably left with following approach:
Extract all text from each page
Analyze text and find similar parts at the beginning / end of each page
Remove similar parts
This is a heuristic-based detection, so it probably won't always give excellent results.

Append text to PDF in Coldfusion 8

I have a PDF that I want to append some text to. the addFooter() that is available in CF9 would work perfectly, but I only have access to CF8.
Any one have workarounds for this feature in 8?
Thanks
Yes, even in ColdFusion 8 you can use DDX to add footers and headers to a PDF. See the specific Adobe 8 Livedocs on how to do this. I also have a couple blog posts 1 and 2 that might help. ALthough I tested on CF9, there's CF8 valid information as well. You might also want to get the almost impossible to find DDX reference. Also check out ColdFusion Jedi's 8 part series on PDF manipulation in CF8.
UPDATE (Added information below on combining text):
To take PDF1 and PDF2 and put the text on a single page in resulting PDF, the first thing that comes to mind is that you could use cfpdf with the getinfo action to get the text (if you don't already have it in a plain text or HTML format). Then you could cfoutput the text into a cfdocument element of type pdf. That way you get a new merged PDF with the contents combined.

parse pdf and identify page a phrase is on

I want to programmatically parse a pdf file, look for certain phrases and find out the page number that each phrase is on. Is this possible (I understand that pdf is not like a text file)? Is so, are there libraries out there that can help?
Apache Tika, which you can find at the Apache Lucene project, includes PDFBox, which will pull out the text where you can work with it.
