You can change it to false when calling the text() function: pdfDoc.text( "very long text ". The PDFKit API is designed to be simple, so generating complex documents is often as simple as a few function calls. In other words, the lineBreak option is true by default. The pdfkit module automatically wraps lines so that they fit between the margins, or in the width provided (when writing text in columns). PdfDoc.text( "From Mon-Sat we will have a 10% discount on selected items!", 150, 150) This would also allow you to, for example, print text over other text: const PDFDocument = require( 'pdfkit') This is useful because it allows you to fine-tune the positioning of text, especially since PDF documents have a universal look regardless of the machine/OS they are opened on. You can change where the text is printed within the current page, by adding the x and y coordinates of the location where you want the text to be placed as arguments to the text() function.įor example: pdfDoc.text( "Text positioned at (200,200)", 200, 200) Positioning Textīy default, the pdfkit module keeps track of where text should be added to the document, essentially print each call to the text() function in a new line. Let's take a look at some of the features it offers. Of course, pdfkit allows us to do much more than just add unformatted text to a document. I.e - all windows with that PDF file must be closed or the program will throw an error. Note: Before attempting to overwrite an existing PDF file, it must be free. When we run the code, a PDF file called SampleDocument.pdf is created in the root folder of our project: $ node index.js Of course, we'll want to end() the stream in the end. Once created, we can add contents to it, via the text function. We're using the pipe() function to do this and save the resulting SampleDocument.pdf into our root directory. If you're not familiar with how streams work, check out our Introduction to Node.js Streams. We'll be piping that stream into a writeable stream to save the file. PdfDoc.pipe(fs.createWriteStream( 'SampleDocument.pdf')) įirst, we import the required modules, after which, we instantiate the PDFDocument. We'll pipe the contents of our PDF file into a fs's writeable stream to save it. To create a PDF document, we will need to import the fs (file system) module as well. To use the module in the project, we'll import it via require(): const PDFDocument = require( 'pdfkit') Then, let's install pdfkit: $ npm install pdfkit The paragraphs will be flowed inside these margins. Let's create a project directory, cd into it and initialize the Node project with default settings: $ mkdir pdfkit-project $ cd pdfkit-project $ npm init -y The margins of the pages can be set through the Margins properties of Section. PDFKit is a JavaScript PDF generation library for Node.js that provides an easy way to create multi-page, printable PDF documents. In this article, we will discuss how to generate PDF files in NodeJS using the NPM package pdfkit. In dynamic web applications, you might need to export data into a document and PDF is usually a popular option. This is the case if and only if there is exactly one fragment that has a zero font size.The PDF format is one of the most common document formats for transferring information. In addition, you can set the Height property but this is used if the multiline text shape is auto-sized. The text will be automatically split up into multiple lines based on the Width you specified. Using file As New FileStream(".\.\multilinetext.pdf", FileMode.Create, FileAccess.Write) ' Y corresponds to the top of the paragraph Translate.X = (page.Width - multilineText.Width) / 2 Using (FileStream file = new FileMode.Create, FileAccess.Write))ĭim page As New Page(PageSize.Letter, landscape)ĭim multilineText As New MultilineTextShape()ĭim translate As New TranslateTransform()ĭim fragment As New Fragment(text, Font.TimesRoman, 12) MultilineTextShape multilineText = new MultilineTextShape dock text to the top of the shapes collection - align leftįragment fragment = new Fragment(text, Font.TimesRoman, 16) Shapes.Transform = new TranslateTransform ShapeCollection shapes = new ShapeCollection it will be the container for multiline text shapes NET In the following code sample you can see how you can easily merge PDF files into one. add a shapes collection at the center of the page This code sample demonstrates how to use the event mechanism to calculate the height of a paragraph in a PDF. create a new document with a single page "Add pages, stamp content and fill forms."
