module Parsers
#
# Within the markdown file the image paths are relative to the markdown
# file. This parser will convert any image paths specified within the
# markdown and convert them to relative to the presentation root.
#
# This parsing functionality ensures that the image path when this is
# later rendered to HTML will have the correct path.
#
# @example 
#
# "" # => ""
#
class MarkdownImagePaths
#
# Convert all the image paths within the markdown content with the
# specified path parameter.
#
# @example Update all image paths to be prefixed with 'section'
#
# MarkdownImagePaths.parse(markdown_content, :path => 'section')
#
#
# @param [String] content markdown content that may or may not contain
# image tags.
# @param [Hash] options that contains parameters to help to properly
# convert the image path.
