ITEXTSHARP CLONE PDF

In this chapter, we'll do some more document manipulation, but there will be a subtle difference in approach. We manipulated a single document. In this chapter, we'll always create at least two PdfDocument instances: one or more for the source document s , and one for the destination document. Now we want to create a PDF file with three pages. In page one, the original page is scaled down to

You probably remember the Superman PDF from topic 5. The Hero example imported a plain text file containing PDF syntax into the direct content. Suppose you want to reuse the pages of this document and treat them as if every page were an image. Figure 6. The document in the front of figure 6.

What does this method do? In general, such a content stream contains references to external objects, images, and fonts. In section 3. The corresponding value was a reference to a stream object containing the bits and bytes of the image. The Hero example was an exception: the syntax to draw the vector image of Superman was self-contained, and this is very unusual. Instead, you should pass the reader object to the writer class, and ask the writer not the reader! A PdfImportedPage object is returned.

Behind the scenes, all the necessary resources such as images and fonts are retrieved and copied to the writer. In general, these features are called annotations.

They include links, text annotations, and form fields. The original dimensions of each imported page are the same as the original media box, but in this example, the PdfImportedPages are scaled to fit inside a table.

You can see the result in figure 6. Observe that cell and image rotations go counterclockwise. You can transform pages in iText , just like you can transform images. Do you remember figure 3. That was the image I used to explain the different content layers used by iText. I created this image by generating a document with four pages, and then importing those pages into a new one; see figure 6. The imported pages are added to the new PDF document using addTemplate.

The parameters are calculated so that each page is scaled and skewed. Superimposing means that you add different PDF pages on top of each other on the same page. You could do this with the four pages shown to the left in figure 6. Superimposing is often used to create documents with a standard header and footer. Suppose your company has preprinted paper containing the company name and logo in the letterhead, and maybe also a watermark. All letters are printed on this company stationery.

You can achieve something similar with PDF, as shown in figure 6. In figure 6. When creating a new document, as shown to the right, the template page is imported and added to the background of each new page using a page event. To cut paper costs by 50 percent when printing a PDF document, you can copy an existing PDF into a new one that has half the number of pages. All you have to do is put two pages next to each other on one page.

This is called 2-up copying. The opposite of W-up copying a PDF file is when you have one page, and you want to print it on different pages; see figure 6. The next bit of code takes one page from a PDF document and scales it so that the one page is "tiled" over 16 pages. You can take digital photocopies of existing pages, scale them up or down, and use them as if they were an image or an XObject.
