NAME
Text::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 CWPDF::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 CW$force_memory is set, this caching will not occur and the data will all be stored in the CW$self->{' stream'} variable.
$d->val
Returns the dictionary, which is itself. Copies an object. See Text::PDF::Objind::Copy() for details
