The goal of create pdf using itextsharp c# organization is to digitize and make available legacy biodiversity literature. One popular feature of the BHL web site is the ability for visitors to select up to 100 pages from a book and generate a PDF containing those pages.
More than 100 custom PDFs are created each day. As the primary developer of the site, I want to highlight the tool that we use to generate the PDFs. The official website for the component points you to the documentation for the original Java tool. I found that these discrepancies between the Java documentation and the .
NET implementation led to many instances of trial-and-error development. You can download the compiled assembly, or if you prefer, the source code. Included are examples of basic text layout and formatting, image insertion, page sizing, page labeling, metadata assignment, bullet lists, and linking. The rest of the code samples build on this one. Add metadata to the document.
Add Xmp metadata to the document. The code starts by setting up the fonts that will be used within the PDF. In fact, these are used in most of the following code samples. You can see that various font faces, sizes, weights, and colors can be specified.
Next, margins and page size are set. At this point the content of the document has been completely written. The only other thing to point out in this sample is the error handling. Notice that when adding a paragraph, you can specify the alignment and font to be used to render the paragraph contents. Next, a small JPG image is read from disk and inserted into the document.
The method finishes up by adding two more paragraphs to the page. Add the header page to the document. Note the use of fonts and alignment attributes. What kind of paper is the best for making paper airplanes? Add a paragraph object containing the specified element to the PDF document. Document to which to add the paragraph.
Font to assign to the paragraph. Object that is the content of the paragraph. These actions include setting the alignment, font, and content. Notice that the content is not restricted to text. IElement interface can form the content of a paragraph. This means that plain text, anchor tags, external links, and other objects can be used.
Notice that as with paragraphs and other text fragments, i add a PdfPTable as footer in last page? I tried doing this by converting an html page to PDF but as you found while this is easy in theory, the method is a simple one. We will create a list and store some data in the list. This time the PDF will be displayed instead of your view, add a page that includes a bullet list.
If you are familiar with how to link to anchor tags in an HTML document, then you should understand what is happening in this example. As you can see, the method is a simple one. These are references to named anchors are found in other locations in the finished PDF document. Creation of the named anchors is explained in the next code sample. Notice that as with paragraphs and other text fragments, you specify a font when creating the Anchor objects. After the Anchor objects are created, a new page is added to the document, a paragraph of text is added to the page, and then the three Anchor objects are added to the page.
Add a blank page to the document. It shows how to create the named anchors that were referenced by the anchors created in the previous example. In addition, it shows a new concept, a bulleted list. In this method, after adding a new page to the document, a new Anchor object is created and added to the page.
