![]() ![]() Certainly I must be doing something wrong. I can't believe that this is the case for such an established platform. ![]() It would seem that registered fonts only allow one font to be registered at a time. In the example above, ALL FOUR fonts are rendered using the "Thin" font file. I set some options, build the new PDF, register my fonts, then create some VERY simple blocks of text. It would seem that when I register a custom font (.ttf) only the first declared font is used, even when I reference other registered fonts. My question is related to registering fonts. PDFKit is available under the MIT license.įirst off, i have to say how much i LOVE this platform. Documentationįor complete API documentation and more examples, see the PDFKit website. If you forget to install it, Browserify will print an error message. It is listed as a devDependency in PDFKit's package.json, so it isn't installed by default for Node users. Note that in order to Browserify a project using PDFKit, you need to install the brfs module with npm, which is used to load built-in font data into the package. You can see an interactive in-browser demo of PDFKit here. text ( 'Some text with an embedded font!', 100, 100 ) // Add an image, constrain it to a given size, and center it vertically and horizontally doc. createWriteStream ( 'output.pdf' ) ) // Embed a font, set the font size, and render some text doc. Even more awesomeness, perhaps written by you! Please fork this repository and send me pull requests.Ĭonst PDFDocument = require ( 'pdfkit' ) const fs = require ( 'fs' ) // Create a document const doc = new PDFDocument ( ) // Pipe its output somewhere, like to a file or HTTP response // See below for browser usage doc.Higher level APIs for creating tables and laying out content.Accessibility support (marked content, logical structure, Tagged PDF, PDF/UA).Access privileges (printing, copying, modifying, annotating, form filling, content accessibility, document assembly).Supports JPEG and PNG files (including indexed PNGs, and PNGs with transparency).See fontkit for more details on advanced glyph layout support.Supports TrueType (.ttf), OpenType (.otf), WOFF, WOFF2, TrueType Collections (.ttc), and Datafork TrueType (.dfont) fonts.Just type the following command after installing npm. ![]() ![]() Installation uses the npm package manager. You can also try out an interactive in-browser demo of PDFKit here. If you'd like to see how it was generated, check out the README in the docs folder. The PDFKit API is designed to be simple, so generating complex documents is often as simple as a few function calls.Ĭheck out some of the documentation and examples to see for yourself! You can also read the guide as a self-generated PDF with example output displayed inline. The API embraces chainability, and includes both low level functions as well as abstractions for higher level functionality. PDFKit is a PDF document generation library for Node and the browser that makes creating complex, multi-page, printable documents easy. Configuring the ContextĪs a next step, we are going to implement a function that takes a cocktail, extracts all the relevant information, and using the previous extensions, adds it to the context.A JavaScript PDF generation library for Node and the browser. After doing so, we use the function 4 ( checkContext()) that will check if our text is exceeding the bounds of the page, and if so, start a new page dynamically and reset the cursor.įinally, the function 5 calculates the height of a multi-line sentence, so that we know where the text ends and where to start the next paragraph. We then use the indent and Page Size parameters to place our string in a CGRect described by the function definition (centered, single line left aligned, and multi-line left aligned). In the implementation of functions 1, 2 and 3, attributes are assigned to our text in an Attributed String variable. These methods are added as an extension to UIGraphicsPDFRendererContext, which is the context that is going to render our PDF.Īll we have to do is dictate to the context everything we need our PDF to have (PDF metadata, PDF dimensions, page breaks, and of course the text we are going to present on the document). ![]()
