.SH "NAME"
PDF::API2::Basic::PDF::Pages \- Low\-level page tree object
.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
A Pages object is the parent to other pages objects or to page objects
themselves.
.SH "METHODS"
.IX Header "METHODS"
.ie n .SS "PDF::API2::Basic::PDF::Pages\->new($pdf, $parent)"
.el .SS "PDF::API2::Basic::PDF::Pages\->new($pdf, \f(CW$parent\fP)"
.IX Subsection "PDF::API2::Basic::PDF::Pages->new($pdf, $parent)"
This creates a new Pages object in a \s-1PDF.\s0 Notice that \f(CW$parent\fR here is
not the file context for the object but the parent pages object for
this pages. If we are using this class to create a root node, then
\&\f(CW$parent\fR should point to the file context, which is identified by not
having a Type of Pages.  \f(CW$pdf\fR is the file object (or a reference to an
array of file objects) in which to create the new Pages object.
.ie n .SS "$p\->find_page($page_number)"
.el .SS "\f(CW$p\fP\->find_page($page_number)"
.IX Subsection "$p->find_page($page_number)"
Returns the given page, using the page count values in the pages tree. Pages
start at 0.
.ie n .SS "$p\->add_page($page, $page_number)"
.el .SS "\f(CW$p\fP\->add_page($page, \f(CW$page_number\fP)"
.IX Subsection "$p->add_page($page, $page_number)"
Inserts the page before the given \f(CW$page_number\fR. \f(CW$page_number\fR can be negative to
count from the \s-1END\s0 of the document. \-1 is after the last page. Likewise
\&\f(CW$page_number\fR can be greater than the number of pages currently in the document,
to append.
.ie n .SS "@objects = $p\->\fBget_pages()\fP"
.el .SS "\f(CW@objects\fP = \f(CW$p\fP\->\fBget_pages()\fP"
.IX Subsection "@objects = $p->get_pages()"
Returns a list of page objects in the document in page order
.ie n .SS "$p\->find_prop($key)"
.el .SS "\f(CW$p\fP\->find_prop($key)"
.IX Subsection "$p->find_prop($key)"
Searches up through the inheritance tree to find a property.
.ie n .SS "$p\->add_font($pdf, $font)"
.el .SS "\f(CW$p\fP\->add_font($pdf, \f(CW$font\fP)"
.IX Subsection "$p->add_font($pdf, $font)"
Creates or edits the resource dictionary at this level in the hierarchy. If
the font is already supported even through the hierarchy, then it is not added.
.ie n .SS "$p\->bbox($xmin, $ymin, $xmax, $ymax, [$param])"
.el .SS "\f(CW$p\fP\->bbox($xmin, \f(CW$ymin\fP, \f(CW$xmax\fP, \f(CW$ymax\fP, [$param])"
.IX Subsection "$p->bbox($xmin, $ymin, $xmax, $ymax, [$param])"
Specifies the bounding box for this and all child pages. If the values are
identical to those inherited then no change is made. \f(CW$param\fR specifies the attribute
name so that other 'bounding box'es can be set with this method.
.ie n .SS "$p\->proc_set(@entries)"
.el .SS "\f(CW$p\fP\->proc_set(@entries)"
.IX Subsection "$p->proc_set(@entries)"
Ensures that the current resource contains all the entries in the proc_sets
listed. If necessary it creates a local resource dictionary to achieve this.
.ie n .SS "$p\->get_top"
.el .SS "\f(CW$p\fP\->get_top"
.IX Subsection "$p->get_top"
Returns the top of the pages tree
