VERSION

version 0.006

EXTENDS

ATTRIBUTES

filename

A required File attribute that represents the location of the PDF file.

string

A required Str attribute that represents the raw string output from mutool show.

is_toplevel

An optional Bool attribute that tells whether the data is top-level or not. This influences the parsing by removing the header from the mutool show output.

Default: true

data

A Str containing the parsed data.

type

Contains the type parsed in the data attribute. See "Types" for more information.

CLASS METHODS

unescape_ascii_string

classmethod unescape_ascii_string((Str) $pdf_string )

A class method that unescapes the escape sequences in a PDF string.

Returns a Str.

decode_hex_utf16be

classmethod decode_hex_utf16be( (Str) $pdf_string )

A class method that decodes data stored in angle brackets.

Currently only implements Unicode character encoding for what is called a UTF-16BE encoded string with a leading byte order marker using ASCIIHexDecode:

  • first two bytes must be the Unicode byte order marker (U+FEFF),

  • one byte per each pair of hex characters (/[0-9A-F]{2}/))

  • whitespace is ignored

See the following parts of PDF Reference 1.7:

  • Section 3.3.1 ASCIIHexDecode Filter (pg. 69) and

  • Section 3.8.1 Text String Type (pg. 158)

Returns a Str.

METHODS

BUILD

Initialises the object by parsing the input data.

resolve_key

method resolve_key( (Str) $key )

A method that follows the reference IDs contained in the data for the until a non-reference type is found.

Returns a Renard::API::MuPDF::mutool::ObjectParser instance.

new_from_reference

method new_from_reference( (InstanceOf['Renard::API::MuPDF::mutool::ObjectParser']) $ref_obj )

Returns an instance of Renard::API::MuPDF::mutool::ObjectParser that follows the reference ID contained inside $ref_obj.
