For instance, there is a text field, a checkbox field, a combobox field, and more. Typically, the person. PDF on her computer interacts with the document's fields; however, it is possible to enumerate and fill a PDF's fields programmatically, as we saw in last. We start with an example of how to programmatically define and piece. PDF file. Following that, we explore how to use i. Text. Sharp's built- in capabilities to convert HTML into PDF.

Writer. object is responsible for serializing the PDF document you create to some store, such as in memory or to disk. Add various elements to the Document object - paragraphs, tables, images, and so on. Steps one and two are easy enough to implement and take just a couple of lines of code in total. Step 3, however, is where the bulk of the work is done. The code for Step 3 can be long - the bigger and more. PDF document you are trying to create, the more intricate this code will be. Step 3: Add elements to the document! In doing so we need to specify two bits of information - the Document object being created and a Stream. Document object's output should be serialized when it is closed. In the code above we are using a File. Stream, which will cause the. PDF document's contents to be serialized to a file on disk named My. First. PDF. pdf. At this point we're ready for Step 3 - adding the assorted elements to the document. Once all of the elements have been. Pdf. Writer object to . There are classes in. Text. Sharp library that model these various element types. To add an element type to the document you (typically) create an instance of the appropriate element type. Document object via the Add method. For example, the following code snippet adds a new Paragraph. There are individual. The. page contains user interface elements where the user can enter the Order number, price, and what items were ordered, and these selections are used to dynamically create. PDF receipt. Of course, in a real- world application this information would be pulled from a database and not hand- entered by a user. Here, we are creating a receipt for Order 1. Here, we are serializing the PDF to a Memory. Stream. Note that when creating a new Paragraph object we can optionally specify its font. In this case, we use the title. Font. which will display the receipt title in an 1. Arial bold font. Here we specify that the table has two columns. The code below creates a 2x. ID and total price. There's. also an ending message at the bottom of the receipt - . This image - 4guysfromrolla. Images folder. If you add the Image object to the document like the other text elements it. However, you can specify an absolute position for the image, which I do here, to locate it in the upper. This is accomplished. Close(); Response. Content. Type = . The next line of code adds the Content- Disposition HTTP header to the. This tells the browser to treat the content like an attachment, meaning the user will be prompted whether to open or save the PDF (rather than having it open. Note that we can tell the browser the name of the file being sent, which the browser will use as the suggested name should the user. PDF to their hard drive. Here we use the filename Receipt- Order. ID. pdf. Recall that output is the Memory. Stream. object we created when instantiating the Pdf. Writer object. Using this class you can, with just a few lines of code. HTML document into a PDF file. For example, rather than building the receipt programmatically, adding each element one at a time as we did in the previous demo. HTML template. This HTML file. Your order details are below. If you have any questions about your order, please contact us at. NORTH. There's a table for the order details, a . The idea here is that before we ask i. Text. Sharp to turn. PDF we will first replace those placeholders with the Order ID, total price, and other metrics for the order we are generating a receipt for. This returns a collection of elements. Add each element returned in Step 3 to the Document object. Steps 1 and 2 are identical to the first two steps for creating a PDF document from scratch. For our demo, Step 3 - reading in the HTML - involves two sub- steps. First. we must read in the HTML contents of the Receipt. Following that, we need to replace the placeholders with the appropriate values. These user- supplied values are what are used to. Receipt. htm. The code simply builds the markup for a < table> by looping through the Check. Box. List and. adding a table row (< tr> ) for each selected purchased item. Step 4 - calling i. Text. Sharp's HTMLWorker. Parse. To. List method - parses the HTML string. Step 5 enumerates this collection of elements, adding them to the Document object. Keep in mind that the HTML parser is simply converting HTML into elements that can be added to the PDF document. In addition to adding these. Create. PDFFrom. Scratch. For instance, we can add the.

NET component downloadable at http: //sourceforge. After we have downloaded and unzipped the i. Text. Sharp dll and created our project we need to add a reference to i. Text. Sharp. dll.

First we create a file stream object representing the actual file and name it to whatever you want.(By using the method Map. Path we target the folder we created earlier as this is a Web application) System. IO. File. Stream fs = new. File. Stream(Server. Map. Path(. Then use that object and the file stream to create the Pdf. Writer instance enabling us to output text and other elements to the PDF file.// Create an instance of the document class which represents the PDF document itself. Document document = new. Document(Page. Size. A4, 2. 5, 2. 5, 3. Create an instance to the PDF file by creating an instance of the PDF // Writer class using the document and the filestrem in the constructor. Pdf. Writer writer = Pdf. Writer. Get. Instance(document, fs); A good thing is always to add meta information to files, this does it easier to index the file in a proper way.
