  This manual is a collection of examples categorized by theme and organized from the least to the most complex. While it covers most of the common use cases it is not a comprehensive guide.

  The best way to read it depends on your previous knowledge of Prawn and what you need to accomplish.

  If you are beginning with Prawn the first chapter will teach you the most basic concepts and how to create pdf documents. For an overview of the other features each chapter beyond the first either has a Basics section (which offer enough insight on the feature without showing all the advanced stuff you might never use) or is simple enough with only a few examples.

  Once you understand the basics you might want to come back to this manual looking for examples that accomplish tasks you need.

  Advanced users are encouraged to go beyond this manual and read the source code directly if any doubt is not directly covered on this manual.

  The title of each example is the relative path from the Prawn source manual/ folder.

  The first body of text is the introductory text for the example. Generaly it is a short description of the features illustrated by the example.

  Next comes the example source code block in fixed width font.

  Most of the example snippets illustrate features that alter the page in place. The effect of these snippets is shown right below a dashed line. If it doesn't make sense to evaluate the snippet inline, a box with the link for the example file is shown instead.

  Note that the <code>stroke_axis</code> method used throughout the manual is part of standard Prawn. It is defined in this file:
