to view the email preview (note the PDF attachment included in the email):  ## Prawn PDF [Prawn PDF](https://github.com/prawnpdf/prawn) is a pure Ruby PDF- generation library that comes packed with features, such as PNG and JPG image embeds, generated file encryption, right-to-left text rendering, a way to incorporate outlines for easy document navigation, and a lot more. Prawn comes with its own DSL, which drives its powerful PDF generation abilities. ### When to Use Prawn Although it's not a fully featured report generation library like the well-known [Jasper Reports](https://community.jaspersoft.com/), with a bit of work using it's powerful DSL, you can generate some really cool and rather complex PDF documents with Prawn. Even so, it's important to note that Prawn isn't everything. If you want to generate PDFs from HTML, then you should look elsewhere, as the gem provides very limited support for inline styling, something of a hurdle if you're working with rich HTML documents. ### Installing and Using Prawn To get started with Prawn, install it with this command: ```bash gem install prawn
Like the WickedPDF gem, the PDFkit gem uses wkhtmltopdf on the backend to convert plain HTML and CSS files into PDF documents.
