.IX Title "Text::PDF::Dict 3pm"
.TH Text::PDF::Dict 3pm "2006-09-09" "perl v5.8.8" "User Contributed Perl Documentation"
.SH "NAME"
Text::PDF::Dict \- PDF Dictionaries and Streams. Inherits from PDF::Objind
.SH "INSTANCE VARIABLES"
.IX Header "INSTANCE VARIABLES"
There are various special instance variables which are used to look after,
particularly, streams. Each begins with a space:
.RE
.IP "stream"
.IX Item "stream"
Holds the stream contents for output
.RE
.IP "streamfile"
.IX Item "streamfile"
Holds the stream contents in an external file rather than in memory. This is
not the same as a \s-1PDF\s0 file stream. The data is stored in its unfiltered form.
.RE
.IP "streamloc"
.IX Item "streamloc"
If both ' stream' and ' streamfile' are empty, this indicates where in the
source \s-1PDF\s0 the stream starts.
.SH "METHODS"
.IX Header "METHODS"
.Sh "$d\->outobjdeep($fh)"
.IX Subsection "$d->outobjdeep($fh)"
Outputs the contents of the dictionary to a \s-1PDF\s0 file. This is a recursive call.
.PP
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.
.Sh "$d\->read_stream($force_memory)"
.IX Subsection "$d->read_stream($force_memory)"
Reads in a stream from a \s-1PDF\s0 file. If the stream is greater than
\&\f(CW\*(C`PDF::Dict::mincache\*(C'\fR (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 \f(CW$force_memory\fR is set, this caching will not
occur and the data will all be stored in the \f(CW$self\fR\->{' stream'}
variable.
.Sh "$d\->val"
.IX Subsection "$d->val"
Returns the dictionary, which is itself.
.ie n .Sh "$d\->copy($inpdf, $res\fP, \f(CW$unique\fP, \f(CW$outpdf\fP, \f(CW%opts)"
.el .Sh "$d\->copy($inpdf, \f(CW$res\fP, \f(CW$unique\fP, \f(CW$outpdf\fP, \f(CW%opts\fP)"
.IX Subsection "$d->copy($inpdf, $res, $unique, $outpdf, %opts)"
Copies an object. See \fIText::PDF::Objind::Copy()\fR for details
