pdf::api2::basic::pdf::dict

PDF::API2::Basic::PDF::Dict(3pm)			User Contributed Perl Documentation			  PDF::API2::Basic::PDF::Dict(3pm)

NAME

       PDF::API2::Basic::PDF::Dict - PDF Dictionaries and Streams. Inherits from PDF::Objind

INSTANCE VARIABLES

       There are various special instance variables which are used to look after, particularly, streams. Each begins with a space:

       stream
	   Holds the stream contents for output

       streamfile
	   Holds the stream contents in an external file rather than in memory. This is not the same as a PDF file stream. The data is stored in
	   its unfiltered form.

       streamloc
	   If both ' stream' and ' streamfile' are empty, this indicates where in the source PDF the stream starts.

METHODS

   $d->outobjdeep($fh)
       Outputs the contents of the dictionary to a PDF file. This is a recursive call.

       It also outputs a stream if the dictionary has a stream element. If this occurs then this method will calculate the length of the stream
       and insert it into the stream's dictionary.

   $d->read_stream($force_memory)
       Reads in a stream from a PDF file. If the stream is greater than "PDF::Dict::mincache" (defaults to 32768) bytes to be stored, then the
       default action is to create a file for it somewhere and to use that file as a data cache. If $force_memory is set, this caching will not
       occur and the data will all be stored in the $self->{' stream'} variable.

   $d->val
       Returns the dictionary, which is itself.
