VERSION

### Attributes

debug[RW]

Whe set to true, Prawn will verify hash options to ensure only valid keys are used. Off by default.

Example:

    >> Prawn::Document.new(:tomato => "Juicy")
    Prawn::Errors::UnknownOption:
    Detected unknown option(s): [:tomato]
    Accepted options are: [:page_size, :page_layout, :left_margin, ...]

### Public Instance Methods

PdfObject(obj, in_content_stream = false) click to toggle source

Serializes Ruby objects to their PDF equivalents. Most primitive objects will work as expected, but please note that Name objects are represented by Ruby Symbol objects and Dictionary objects are represented by Ruby hashes (keyed by symbols)

    Examples:

       PdfObject(true)      #=> "true"
       PdfObject(false)     #=> "false"
       PdfObject(1.2124)    #=> "1.2124"
       PdfObject("foo bar") #=> "(foo bar)"
       PdfObject(:Symbol)   #=> "/Symbol"
       PdfObject(["foo",:bar, [1,2]]) #=> "[foo /bar [1 2]]"
