Open Source PDF

  1. Open Source PDF Libraries in Java
    iText is a library that allows you to generate PDF files on the fly. The iText classes are very useful for people who need to generate read-only, platform independent documents containing text, lists, tables and images. The library is especially useful in combination with Java(TM) technology-based Servlets: The look and feel of HTML is browser dependent; with iText and PDF you can control exactly how your servlet's output will look.It provides a simple API to create pdf files and print using subclasses of java.awt.Graphics and java.awt.PrintJob. The PDF classes write to an OutputStream in pdf format instead of a typical Graphics object, but the method calls are the same as they would be in any Applet or Application drawing to a canvas.
     
  2. Portable Document Format
    Portable Document Format (PDF) is an open standard file format, proprietary to Adobe Systems, for representing two dimensional documents in a device independent and resolution independent format. Each PDF file encapsulates a complete description of a 2D document (and, with the advent of Acrobat 3D, embedded 3D documents) that includes the text, fonts, images, and 2D vector graphics that compose the document. Importantly, PDF files do not encode information that is specific to the application software, hardware, or operating system used to create or view the document. This feature ensures that a valid PDF will render exactly the same regardless of its origin or destination.
    PDF is also an open standard in the sense that anyone may create applications that read and write PDF files without having to pay royalties to Adobe Systems; Adobe has a number of patents relating to the PDF format, but licenses them on a royalty-free basis for use in developing software that complies with the PDF specification.

  3. Open Source Development with CVS
    The complete Open Source Development with CVS, 3rd Edition is available under the GNU General Public License The electronic copy of the 3rd edition comes directly from the publisher's PDF files. Due to certain complexities of the publishing process, there are no source files from which the PDFs were generated. Therefore, I simply distribute the PDFs as masters; they serve as both source and binary format. I am no longer fixing bugs in the book, due to lack of time. However, if you spot errors in these web pages.
      
  4. Open Source Software
    Open source software (OSS) is computer software that has its underlying ?source-code? made available under a licence. This can allow developers and users to adapt and improve it. Policy on the use of OSS in governmen was updated in 2004. This briefing explains how OSS
    works, outlines current and prospective uses and examines recent policy developments. It discusses its advantages and disadvantages and examines factors affecting uptake. Computer software can be broadly split into two
    development models (see Box 1 for definitions):
    ? Proprietary, or ?closed? software, owned by a company or individual. Copies of the ?binary? are made public; the ?source-code? is not  usually made public1.
    ? Open source software (OSS), where the source-code is released with the binary. Users and developers can be licenced to use and modify the code, and to distribute any improvements they make2.

       
  5. Open Source And Open Innivation
    Fostering economic growth has long been at the heart of the mission of the Committee for Economic Development (CED). As the ?digital economy? became a reality, CED established the Digital Connections Council to help it better understand the implications of this new economic frontier. In 2004, the Digital Connections Council issued a report addressing the ?special problem? of digital intellectual property and its impact on innovation and economic growth. The report noted three important trends: the increasing digitization of all forms of information; the growing importance of intangible property; and the replacement of the sale of digital information in its many forms by various licensing agreements made between the rights holder and the consumer.
