Oct 18, 2008 - Just as HTML and ASP.NET provide. As with the Label, you need to be careful how you use Chunks. The following snippet shows how to set the text of a Chunk, then write it to the PDF document 3 times: string path = Server. When you call Convert (string) method to convert Msg file to Html File, each Msg will give you an Html file and a directory. The image of the Html page is in the directory. So when you create PDF file, itextsharp.dll will try to find the image, but failed and throw this exception. The easiest way to fix this issue is to use the Html all in one.

4.12 Creating PDFs with iTextSharp Adobe’s PDF format is one of the most widely accepted document formats in use today. Most users and clients expect that the software you write will be able to generate and work with PDFs. Unfortunately, however, Adobe does not offer a free SDK that you can download and use; you have to pay to license the API, and a fair amount of work is usually required to get it up and running. ITextSharp alleviates this problem. ITextSharp is a port of the iText Java PDF library that gives you the ability to add PDF functionality to your applications. Using iTextSharp, you can create and read PDF files without any costs or proprietary software, so you can deliver the functionality your users expect. Using iTextSharp To start, you’ll need to add a couple of using statements to your code: using iTextSharp.text; using iTextSharp.text.pdf; Then create a Document object: Document pdfDocument = new Document( ); Next, create an instance of the PdfWriter and point it to where you want to save this document.
In this example I’ll save to a file on the hard drive, but you can save it to any valid IO stream: PdfWriter.GetInstance(pdfDocument, new FileStream('C: WDPT.PDF', FileMode.Create)); Open the document and add some content: pdfDocument.Open( ); pdfDocument.Add(new Paragraph('Here is a test of creating a PDF')); Then close it. You don’t need to flush the stream or actually write out the document. Close( ) does it all for you in one call: pdfDocument.Close( ); The document created can be seen in. Figure 4-25. A simple PDF Of course, your requirements will rarely be so simple. ITextSharp offers a wide range of features to create more complex PDFs. In the previous example, we used a paragraph to add text to the document, but you can also use phrases and chunks to create the text you want.
A chunk is simply any piece of text with a consistent style; using it, you can specify independent fonts and colors. A phrase is a collection of chunks that includes a leading separator (the amount of vertical space between lines). Chunks and phrases can be added to paragraphs or added directly to documents. Let’s create a couple of chunks with different fonts: Chunk c = new Chunk('Some text in Verdana n', FontFactory.GetFont('Verdana', 12 )); Chunk c2 = new Chunk('More text in Tahoma', FontFactory.GetFont('Tahoma', 14)); and then create a paragraph and add those chunks: Paragraph p = new Paragraph( ); p.Add(c); p.Add(c2); You can see the results in, where both chunks have their respective fonts. Figure 4-26. Chunks with fonts iTextSharp also provides support for working with images and embedding those images in your documents. Images can be added through URLs: Image image = Image.GetInstance( 'or from the filesystem: Image image = Image.GetInstance('home_tarsier.jpg'); PNG, GIF, JPEG, and WMF images can be loaded in this way. You can now add the image to the document or paragraph with the following code: Document pdfDocument = new Document( ); PdfWriter.GetInstance(pdfDocument, new FileStream('C: WDPT.PDF', FileMode.Create)); pdfDocument.Open( ); Image image = Image.GetInstance( 'Chunk c = new Chunk('Check out this wicked graphic: n', FontFactory.GetFont('Verdana', 12 )); Paragraph p = new Paragraph( ); p.Add(c); p.Add(image); pdfDocument.Add(p); pdfDocument.Close( ); The generated PDF is shown in.
