Mars is an XML-friendly representation for PDF documents

Friday, July 27th, 2007 by rubypdf

The Mars (code name) Project is an XML-friendly representation for PDF documents. Already an open specification, PDF is the global standard for trusted, high fidelity electronic documentation. The Mars file format incorporates additional industry standards such as SVG, PNG, JPG, JPG2000, OpenType, Xpath and XML into ZIP-based document container. The Mars plug-ins enable creation and recognition of the Mars file format by Adobe Acrobat 8.1 Professional and reading of Mars-format files by Adobe Reader 8.1 software.

There are many exciting use cases where the XML friendly Mars file format makes the construction of applications much easier by:

Creating documents from databases or other enterprise applications.
Assembling documents from components.
Merging documents including structure, pages, and navigation.
Extracting document information such as comments, structure, content, and images.
Adding document navigation, interactive behavior, multimedia, and 3D content to increase document value.
Decomposing documents into parts for storage in libraries, databases, or content management systems.
Validating document representation, content, and structure.
Creating and processing forms.
Packaging sets of documents and coordinating their presentation and operation.

Update: Mars beta 2 was released on June 25, 2007. Get it now.

Using the iTextSharp library in Delphi .NET

Thursday, July 19th, 2007 by rubypdf

from http://www.noliturbare.com/iTextDelphi.php

This example, taken from from the iText tutorial,
demonstrates how easy the iTextSharp library can be used in Delphi .NET,
using the free (!) Explorer Edition of Turbo Delphi .NET, to create or manipulate PDF’s.
Note that there is also a difference between the original example and the Delpi one:
this C# example is a command line application and the Delphi application is a Windows application.
When run, this simple application creates a PDF file containing just the text “Hello World”.

C# Hello World example

using System; using System.IO; using iTextSharp.text;


using iTextSharp.text.pdf;
namespace iTextSharp.tutorial.Chap01

  {

  public class Chap0101

    {

    public Chap0101()

      {

      Console.WriteLine("Chapter 1 example 1: Hello World");

      // step 1: creation of a document-object

      Document document = new Document();

      try

        {

        // step 2:-->
        // we create a writer that listens to the document

        // and directs a PDF-stream to a file

        PdfWriter.GetInstance(document, new FileStream("Chap0101.pdf", FileMode.Create));

        // step 3: we open the document

        document.Open();

        // step 4: we Add a paragraph to the document

		document.Add(new Paragraph("Hello World"));

		}

      catch(DocumentException de)

        {

        Console.Error.WriteLine(de.Message);

		}

      catch(IOException ioe)

        {

        Console.Error.WriteLine(ioe.Message);

        }

      // step 5: we close the document
      document.Close();

      }

    }

  }

Turbo Delphi .NET Hello World example

{Create a new VCL Forms Application. Add a reference to the iTextSharp.dll. Add a button to the form and apply the following code to the button's onclick event}


uses

  Windows, Messages, SysUtils, ...., iTextSharp.text, iTextSharp.text.pdf;

....

.... 
procedure TForm1.Button1Click(Sender: TObject);

var

   MyDoc  : iTextSharp.text.Document;

   Writer : iTextSharp.text.pdf.PdfWriter;

begin

// step 1: creation of a document-object

MyDoc := Document.Create;

   try

   // step 2: we create a writer that listens to the

   // document and directs a PDF-stream to a file
   Writer := PdfWriter.GetInstance(MyDoc, TFileStream.Create('C:\Chap0101.pdf', fmCreate));

   // step 3: we open the document

   MyDoc.Open();

   // step 4: we Add a paragraph to the document

   MyDoc.Add(Paragraph.Create('Hello World'));

   except

   ShowMessage('Oops... exception');

   end;

// step 5: we close the document
MyDoc.Close();

end;
