opts

A hash of options that may be supplied to the underlying text method call.

Examples:

pdf.icon 'fa-beer'
pdf.icon '<icon color="0099FF">fa-arrows</icon>',

  Text::Formatted::Box.new(content, opts)
end

#make_icon(key, opts = {}) ⇒ Object

Initialize a new icon object, but do not render it to the document.

Parameters:

key

Contains the key to a particular icon within a font family. If :inline_format is true, then key may contain formatted text marked with <icon></icon> tags and any tag supported by Prawn’s parser.

def make_icon(key, opts = {})
  if opts[:inline_format]
    inline_icon(key, opts)
  else
    Icon.new(key, self, opts)
  end
end

#table_icon(key, opts = {}) ⇒ Object

Initialize a new Prawn::Icon, but don’t render the icon to a document. Intended to be used as an entry of a data array when combined with Prawn::Table.

Parameters:

key

Contains the key to a particular icon within a font family. The key may contain a string with format tags if inline_format: true in the opts hash.

opts

A hash of options that may be supplied to the underlying text call.

Returns:

A Hash containing +font+ and +content+ keys
that match the data necessary for the
specified icon.

eg. { font: 'fa', content: '\uf047' }

Note that the +font+ key will not be set
if +inline_format: true+.

Examples:

require 'prawn/table'

data = [
  # Explicit brackets must be used here
  [pdf.table_icon('fa-arrows'), 'Cell 1'],
  ['Cell 2', 'Cell 3']
]

pdf.table(data) => (2 x 2 table)
