PDF::API2::Basic::PDF::Dict - Low-level dictionary and stream objects
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.
Get/Set the standard Type key. It can be passed, and will return, a text value
rather than a Name object.
Get/Set one or more filters being used by the optional stream attached to the
dictionary.
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.
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.
Returns the dictionary, which is itself.
