NAME

       PDF::API2::Basic::PDF::Dict - Low-level dictionary and stream objects

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

   $type = $d->type($type)
       Get/Set the standard Type key.  It can be passed, and will return, a text value rather
       than a Name object.

   @filters = $d->filter(@filters)
       Get/Set one or more filters being used by the optional stream attached to the dictionary.

   $d->outobjdeep($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.
