This page provides Java code examples for singmoundupanvie.ml PdfOptions. The examples are extracted from open source Java projects. Apache POI Tutorial in PDF - Learn Apache POI in simple and easy steps starting from basic to advanced concepts with examples including Overview, Flavours. This tutorial provides a basic understanding of Apache POI library and its features. The API of Apache POI contains a number of methods and classes.

Then you must open it. After that you add content to the document. Finally you close the Document instance. In a paragraph you can set the paragraph alignment, indentation and spacing before and after the paragraph.

Your Answer

Chapter : This class represents a chapter in the PDF document. It is created using a Paragraph as title and an int as chapter number. Font : This class contains all specifications of a font, such as family of font, size, style, and color. Various fonts are declared as static constants in this class. List : This class represents a list, which, in turn, contains a number of ListItems.

PDFPTable : This is a table that can be put at an absolute position but can also be added to the document as the class Table.

Anchor : An Anchor can be a reference or a destination of a reference. A link like we have in HTML pages.

PdfWriter : When this PdfWriter is added to a certain PdfDocument, the PDF representation of every Element added to this Document will be written to the outputstream attached to writer file or network. Simple and clear. In this application, I will create a PDF file with a single statement in content. Usually user will iterates over main document part sections, paragraphs from sections and character runs from paragraph.

Each such interface is a pointer to document text subrange along with additional properties and they all extends same Range parent class.

Some structures like Bookmark or Field can also provide subranges pointers. Changing file content usually requires a lot of synchronized changes in those structures like updating property boundaries, position handlers, etc.

In addition, there is a "one pointer" rule for changing content. It means you should not use two different Range instances at one time. More precisely, if you are changing file content using some range pointer, all other range pointers except parents' ones become invalid. For example if you obtain overall range 1 , paragraph range 2 from overall range and character run range 3 from paragraph range and change text of paragraph, character run range is now invalid and should not be used, but overall range pointer still valid.

Each time you obtaining range pointer new instance is created.

It means if you obtained two range pointers and changed document text using first range pointer, second one became invalid. At the moment, XWPF covers many common use cases for reading and writing. Whilst this is a great thing, it does mean that XWPF does everything that the current POI committers need it to do, and so none of the committers are actively adding new features.

If you come across a feature in XWPF that you need, and isn't currently there, please do send in a patch to add the extra functionality! More details on contributing patches are available on the "Contribution to POI" page.

At the moment we unfortunately do not have someone taking care for HWPF and fostering its development. What we need is someone to stand up, take this thing under his hood as his baby and push it forward. A good starting point seems to be Ryan Ackley's overview. An introduction to the binary file formats is available from Microsoft , which has some good references and links.

After that, the full details on the word format are available from Microsoft , but the documentation can be a little hard to get into at first Try reading the overview first, and looking at the existing code, then finally look up the documentation for specific missing features. I have tried to put as many examples as I found useful to put here to help you all while you work on pdf files in Java. Through given examples use simple java programs, you can reuse this code in web applications.

On brighter side, iText is an open source API. Note that though iText is open source, you still need to download a commercial license if you want to use it for commercial purposes. You can choose from a variety of fonts to be used in the document. Also, the structure of iText allows you to generate any of the above-mentioned types of documents with the same code. The iText library contains classes to generate PDF text in various fonts, generate tables in PDF document, add watermarks to pages, and so on.

There are many more features available with iText which I will leave on you to explore. To add iText into your application, include following maven repository into your pom. Or you can download the latest jar files from maven repository. In this application, I will create a PDF file with a single statement in content.

This example shows how to set various attributes like author name , created date , creator name or simply title of the pdf file. An example to show how images can be added to PDF files.

Example contain adding images from file system as well as URLs. Also, I have added code to position the images within document. Below example will help you in understanding that how to write lists in pdf files using iText library.

Example contains the usage of Fonts as well as chapter and sections as well.

Here writer. In this example, I am setting few file permissions for a pdf file to limit access for other users. Following are several permission values:.

You can provide multiple permissions by ORing different values. For example PdfWriter. This is the last example in list and in this example, I am writing the content of created PDF file into output stream attached to HttpServletResponse object.

This will be needed when you want to stream the PDF file in a client-server environment. Leave a comment if something is not clear to you OR you would like to add any other example into this list.
