This produces a series of lines containing the position of each character, including spaces, that looks like this:. Where 'P' is the character. I have not been able to find a function in PDFbox to find words, and I am not familiar enough with Java to be able to accurately concatenate these characters back into words to search through even though the spaces are also included.
Has anyone else been in a similar situation, and if so how did you approach it? I really only need the coordinate of the first character in the word so that parts simplified, but as to how I'm going to match a string against that kind of output is beyond me. There is no function in PDFBox that allows you to extract words automatically. I'm currently working on extracting data to gather it into blocks and here is my process:. I do an analysis of the coordinates of each glyph, looping over the list.
At this point, I have extracted the different lines of the document be careful, if your document is multi-column, the expression "lines" means all the glyphs that overlap vertically, ie the text of all the columns that have the same vertical coordinates. Then, you can compare the left coordinate of the current glyph to the right coordinate of the preceding one to determine if they belong to the same word or not the PDFTextStripper class provides a getSpacingTolerance method that gives you, based on trials and errors, the value of a "normal" space.
If the difference between the right and the left coordinates is lower than this value, both glyphs belong to the same word. Based on the original idea here is a version of the text search for PDFBox 2.
The code itself is rough, but simple. It should get you started fairly quickly. I finally figured out the character glyph coordinates are private to the. NET assembly, but can be accessed using System.

For the example below you need PDFbox. For those who still need assistance, this is what I used in my code and should be a useful start. It uses PDFBox 2. Learn more. Asked 7 years, 8 months ago.

For this you just need to get the document catalog, then the acroform and then remove all fields from this acroform. For migration from PDFBox 1. This works for sure - I've ran into this problem, debugged all-night, but finally figured out how to do this :.
The other way around doesn't work. After reading about pdf reference guide, I have discovered that you can quite easily set read-only mode for AcroForm fields by adding "Ff" key Field flags with value 1. This is what documentation stands about that:. If set, the user may not change the value of the field. Any associated widget annotations will not interact with the user; that is, they will not respond to mouse clicks or change their appearance in response to mouse motions.
This flag is useful for fields whose values are computed or imported from a database. I created my pdf form in OpenOffice 4.
The 2 items selected in the OpenOffice export dialogue were:. Using PdfBox I populated the form fields and created a flattened pdf file that removed the form fields but retained the form field values. In order to really "flatten" an acrobat form field there seems to be much more to do than at the first glance.
After examining the PDF standard I managed to achieve real flatening in three steps:. All three steps can be done with pdfbox I used 1. Below I will sketch how I did it. A very helpful tool in order to understand whats going on is the PDF Debugger.
In order to save the field's value you have to save its content to the pdf's content for each of the field's widgets. Easiest way to do so is drawing each widget's appearance to the widget's page. The appearance is an XObject stream containing all of the widget's content value, font, size, rotation, etc.

If nothing happens, download GitHub Desktop and try again. If nothing happens, download Xcode and try again.

This project allows creation of new PDF documents, manipulation of existing documents and the ability to extract content from documents. PDFBox also includes several command line utilities. You can download binary versions for releases currently under development or older releases from our Download Page.
The recommended build command is:. The default build will compile the Java sources and package the binary classes into jar packages.
See the Maven documentation for all the other available build options. Please follow the guidelines at our Support Page. This will get you help from the entire community. And there are additional resources available on sites such as Stack Overflow.
If you are sure you have found a bug the please report the issue in our Issue Tracker. Some of the more common issues are:. This is because the characters are a meaningless internal encoding that point to glyphs that are embedded in the PDF document. The only way to access the text is to use OCR. This may be a future enhancement. You get an error message like "java. The easiest solution is to simply include the apache-pdfbox-x.
You get text that has the correct characters, but in the wrong order. This mght be because you have not enabled sorting. The text in PDF files is stored in chunks and the chunks do not need to be stored in the order that they are displayed on a page.PDFBox is an open-source library which is written in Java. It supports the development and conversion of PDF Documents. It is a file format which is used to display a printed document in digital form.
It is independent of the environment in which it was created or the environment in which it is viewed or printed.

Each PDF file has fixed, secure and multidimensional layout including text, fonts, graphics, audio, video, animation and hyperlinks. It was taken up as an Apache project inand became an Apache top level project in It offers unicode support for PDF creation, and has better support for interactive forms.

What is a PDFBox? It contains the classes and interfaces related to the content extraction and manipulation from files. FontBox- It contains the classes and interfaces to handle the font information. Apache Tika- It is a toolkit library which is mainly used for documents type detection and content extraction from various file formats using existing parser libraries.These components are needed during runtime, development and testing dependent on the details below.
The three PDFBox components are named pdfboxfontbox and xmpbox. To add the pdfbox, fontbox, xmpbox and commons-logging jars to your application, the easiest thing is to declare the Maven dependency shown below.
This gives you the main pdfbox library directly and the other required jars as transitive dependencies. PDFBox does not ship with all features enabled. Third party components are necessary to get full support for certain functionality. PDF supports embedded image files, however support for some formats require third party libraries which are distributed under terms incompatible with the Apache 2.
These libraries are optional and will be loaded if present on the classpath, otherwise support for these image formats will be disabled and a warning will be logged when an unsupported image is encountered. Change the scope of the components if needed. Please make sure that any third party licenses are suitable for your project.
These can be included in your Maven project using the following dependencies:. If these files are not installed, building PDFBox will throw an exception with the following message:. The easiest approach is to run mvn dependency:copy-dependencies inside the pdfbox directory of the latest PDFBox source release. You can then simply copy all the libraries you need from this directory to your application. Font Handling For font handling the fontbox component is needed. Include Dependencies Using Maven To add the pdfbox, fontbox, xmpbox and commons-logging jars to your application, the easiest thing is to declare the Maven dependency shown below.
