Recognize Text in (OCR language): By default the OCR language is picked from default locale.; Use available system font: If this option is checked, during the process of scanned to editable text conversion, the converted text is displayed in a font that is installed on the system and is a closest match to the original font in the scanned page. IText 7 for.NET is the.NET version of the iText 7 library, formerly known as iTextSharp, which it replaces. IText 7 represents the next level of SDKs for developers that want to take advantage of the benefits PDF can bring.

Multitudes of FAQs and similar references forPDF information havebeen published in the past. As of 2003, I've found none that I regardas convenient and well-maintained in regard to the 'filters' that transformfiles to and from PDF, not even theConversiontools page of PDFZone orPlanetPDF'sExtraction page--so I'll start my own.The focus of this page ('anyone think Ishould re-do it as a Wiki?)is on the products available to convertto and from PDF images. IDR Solutions explainsthe challenge.
Ghostscript/Ghostview answers many questions, at least partially.
David Boddie's pdftools and David Leonard's PDFFile provide interesting Python-coded raw materials for those unafraid of dirtying their hands with programming. Early in 2005, one appreciated correspondent wrote me that the latter 'handles things like decryption better.' From what I can tell, PDFFile and python-pdftools do not write; they only read.

- 'PDF Bookmark is a high performance server tool ..'
- HTMLDOC inserts bookmarks based on <hN>-tags.
Concatenators
My clients often need to build reports which simply sequence existing(or generated)
.pdf
and/or .ps
source. That'sa far bigger undertaking than you might think, as Matthew Skala documents (in fact, I disagree with a few of his details, but he certainly gets the frustration right). Hereare a few of the alternatives with which I've spent time:- Adobe tools ..
- Aladdin Ghostscript works on many, many of the documents I've encountered. There appear still to be problems. I'll eventually report details of those.
- Ghostscript 7.07 gives up on some colorspaces (perhaps specifically those indexed on an ICC basis with RGB as an alternate color space?), and simply discards corresponding images. Ghostscript before 7.0x can't handle Adobe 6 output. A typical invocation is
- Java-based iText is a very widely-used library for PDF management [Explain mailing list, 1t3xt, and such.] Be aware that, as maintainer Paulo Soares has written [find reference in difficult mailing list], 'If you're using it in an intranet you don't have to do anything. If you're exposing the service to the exterior either you provide the source code of your application or you buy a commercial license.' He was writing about iText 5. Earlier releases could be freely embedded in Web applications.The iText creators (hope to?) receive significant income from the book. While they generously make a wealth of information available on-line, I don't find it organized for my convenience. Among the highlights are:
- a tutorial bundle
- [explain 'Web application']
- JoinPDF appears to be a retail-oriented utility based on iText. It does not bookmark.
- While I have yet to test Tom Phelps' Multivalent, I'm looking forward to it.
- PageCatcher ..
- Perl ..
- pdcat was my favorite concatenator for many years. It's available for many platforms, fast, and, most crucially to me, handles a wider range of inputs than any of the other utilities I've tested. Also, its bookmarking is convenient and correct [explain how far ahead of all others this is]. Still, I have identified a few (obscure?) errors in its operation [explain]. Worse, the old release 2.36 on which I long relied couldn't keep up as 2009 progressed, and I couldn't justify the licensing expense for my applications. In mid-2009, I moved much of my operations to iText. I remain fond of vendor PDF Tools, though.
- In January 2010, we've suddenly switched over many of our operations to
pdfjoin
, a member of the TeX-based pdfjam suite.pdfjoin
handles instances that cause pdftk, pyPdf, and iText to stumble. Phaseit is likely to continue to invest in at least a couple of these different open-source projects. - I haven't yet exercised DocuCom PDF Online, pdfmeld, or pdfpages. pdfmeld's price is modest, and it's documented to be quite flexible, with good capabilities to bookmark, watermark, highlight, underline, and so on.
- Pdftk is a GPLed 'stand-alone, command-line tool that does lots of things, including PDF concatenation,' according to one enthusiast. He provided this example usage: pdftk works well, in my limited testing. It does not bookmark. It does manage background watermarks and foreground stamps. Bruno Lowagie tells me that, while Sid Steward has left computing for a family business, iText Software Corporation 'has plans to set up support for PdfTk'. Here, incidentally, is an interview with Bruno.
- PStill seems to have a good record at concatenating. I want to work more with it.
- In 2009 and 2010, Phaseit began to sponsor some of the work of the open-source Python-based pyPdf library. As of spring 2010, pyPdf is the single solution we most use.
Sometimes it's necessary to decrypt a PDF instance. qpdf is an example of a utility that helps.
Products that extract text from PDF
Don't do it.At least, that's my usual first response, although, as 2004 begins, a couple of products are making me soften that stance. I understand all the situations that make text-extraction appear to be desirable; I've lived through most of them myself. As several sages have counseled, however, from a programmatic standpoint, 'think of PDF as paper', by which they mean you could use scissors and glue on it, but there's almost certainly a better way. Almost always, you're--we're--better off going upstream to the data where the PDFs originated. I'm happy to help analyze specific situations on a consulting basis to determine whether there's an appropriate alternative to text-extraction, and also to help your organization implement the text-extraction method that's best for it. For more on the subject, and especially the possibilities for tabulated data, see this page focused exclusively on content extraction.
If you insist on extracting text from PDF, and choose not to engage our consultancy, you're likely to find your answer from the following list. This list remains partial; you're welcome to write me to ask that I unpack more of my notes, if you have specific requirements none of these meet.

. [doesn't handle compression?] - Adobe has a no-charge, online service that transforms PDF to text. This came about, acccording to the unverified story that reached me, as the result of activism by advocates of the blind, and was part of the price of Adobe's big government contracts.
- [everything else for Windows, including detours by way of RTF]
I've exhorted developers often in my more formal publications not to retrieve text from PDF; a recent example was 'Friends don't let friends ..', in Smart Development.
The most common legitimate reason to render PDF to text is in combination with some sort of search; that's certainly the application of this sort I most often automate. Search and 'content management' specialists are generally aware of the issues involved, and often offer their own PDF extractors as plug-ins or add-ons.

Paginator
Here is the source mentioned in a 'Smart Development post called 'PDF pagination only takes a few lines'. Phaseit, Inc. holds the copyright to this source. Use as you wish. If you make weapons with this code, are ill-humored, claim you originated it yourself, or think a court will support a lawsuit against Phaseit .. well, it's your soul that suffers.
In 2010, I'm testing APDF Number.
Automation
I often field questions such as, 'I need to programmaticallyconvert Office files to PDF. Is that possible / easy? How is that done?'I'll start with a few personal comments.Adobe certainly wants people--especially those who control budget decisions--to think of it as the vendor-of-preferencefor all such needs. I respect Adobe for their business success andtechnical achievements. My experience as a front-line customer oftheirs is .. mixed. Sketch 3 2 – vector drawing application. My first instinct is to look for alternatives.
The dominant producers of PDF documents in the current marketare Acrobat and Word. I suspect someone has reasonably accuratemeasurements of the share each holds; my rough impression is thatthe latter dominates. It certainly is feasible to automate Wordin principle. While most Word scripters use VBA, I rely most onTcl or Python .. There should be no effective barriersto full automation using Word's built-in facilities.
Word, however, emits bad PDF, and is often slow and unreliable,at least for the tasks that matter to me. Adobe frustrates me; Ihave a terrible history at trying to find out the simplest productinformation from the company. When I want 'industrial-strength'automation, I turn toAntiword orOpenOffice.The latter produces higher-quality PDF than Word, and is more open about itsscriptingcapabilities, at leaston an ideologic level.
For special purposes, I've built even more involved 'productionlines' involving intermediate steps with PS, TeX, and other formatsand technologies.
