As soon as you close the stamper, a new document will be created. It will contain only 5 pages. You can add content between the constructor and the close method.
There were two versions of this example. The exisring method is similar to the getDirectContent method discussed in topic 3. It returns a PdfContentByte object that allows you to write to a new layer existin goes on top of the existing content of the page you choose. NOTE The methods getOverContent and getUnderContent give you the option to write to the direct content on a layer that goes on top of or below the existing content.
The media box of the file that was used as the basis for hello3.

The exising used as the basis for hello1. The difference between these two ways of creating a page in landscape is made transparent: In the next code snippet, the extra text was added at the same coordinates as in listing 6. This is prevented with the setRotateContents method. You create a small canvas up front, but you can only add the page number once the document is completely finished. Will the document eventually have 9 pages or ? The document shown in figure 6.
In the first pass, the document is created without a header. The header, and—if necessary—a footer and a watermark, can be added in a second pass. Instead of writing the document to a FileOutputStream in the first pass, you keep the file in memory using a ByteArrayOutputStream see section 1.
In the second pass, you use the bytes from this OutputStream to create a PdfReader instance. There are ktextsharp ways to work around this.
Some applications read a file into memory before changing it; you could read the original file into a byte array and create a PdfReader object as demonstrated in listing 6.
Finally, you could also create the new file in memory using a ByteArrayOutputStream, and then overwrite the original file using these bytes. The “best choice” depends on the context. As a rule of thumb, I prefer temporary files for applications that run on the desktop; in a web environment, I create all files in memory.
This method writes the resources necessary to render the imported page to the writer associated with the stamper. This technique is often used to add watermarks to existing document. You can easily adapt the example to add an Image with the addImage method instead of an imported inswrt.

All the methods from topic 3 are at your disposal. Exiisting can only insert complete pages. You were only able to create the table exizting contents TOC once the document was finished. But you wanted to display the TOC before the rest of the content, not after. You could, for instance, create a ColumnText object containing a series of Paragraphs, then you add these Paragraphs to a number of pages that are inserted into the existing document.
Normally, you have to pass a PdfContentByte object with the constructor.
In G you try to fit the content inside a rectangle. The document created by PdfStamper will start on page 3 itexgsharp the original document, go on until page 41, and then add pages 1 and 2 at the end of the document.
These are practical examples that can be used to solve common problems with the help of PdfStamper, and using the concept of writing to the direct content as discussed in topic 3.

PdfStamper uses a different mechanism, as demonstrated in the manipulateWith-Stamper method.
