    DeckTape

    DeckTape

    PDF exporter for HTML presentations

    DeckTape is a high-quality PDF exporter for HTML presentation frameworks. DeckTape is built on top of Puppeteer which relies on Google Chrome for laying out and rendering Web pages and provides a headless Chrome instance scriptable with a JavaScript API. DeckTape currently supports the following presentation frameworks out of the box. DeckTape also provides a generic command that works by emulating the end-user interaction, allowing it to be used to convert presentations from virtually any kind of framework. The generic mode is particularly useful for supporting HTML presentation frameworks that don’t expose an API or accessible state. DeckTape’s plugin-based architecture exposes an extension API, making it possible to add support for other frameworks or to tailor existing plugins to your specific needs.

    HTML to PDF converter that uses phantomjs

    HTML to PDF converter that uses phantomjs. html-pdf can read the header or footer either out of the footer and header config object or out of the HTML source. You can either set a default header & footer or overwrite that by appending a page number (1 based index) to the id="pageHeader" attribute of an HTML tag. You can use any combination of those tags. The library tries to find any element, that contains the page header or pageFooter id prefix. The full options object gets converted to JSON and will get passed to the phantomjs script as third argument. There are more options concerning the paperSize, header & footer options inside the phantomjs script.

    Use RMarkdown to generate PDF Conference Posters via HTML

    Welcome to Posterdown! This is my attempt to provide a semi-smooth workflow for those who wish to take their RMarkdown skills to the conference world. Many creature comforts from RMarkdown are available in this package such as Markdown section notation, figure captioning, and even citations like this one (Allaire, Xie, McPherson, et al. 2018). The rest of this example poster will show how you can insert typical conference poster features into your own document. Posterdown was created as a proof-of-concept (to myself) that it is possible to make a beautiful poster using open-source reproducible code.
