PDF::API2::Page(3pm) User Contributed Perl Documentation PDF::API2::Page(3pm)
NAME
PDF::API2::Page - Methods to interact with individual pages
SYNOPSIS
my $pdf = PDF::API2->new();
# Add a page to a new or existing PDF
my $page = $pdf->page();
# Set the page size
$page->size('letter');
# Set prepress page boundaries
$page->boundaries(media => '12x18', trim => 0.5 * 72);
# Add an image
my $image = $pdf->image('/path/to/file.jpg');
$page->object($image, $x, $y, $w, $h);
# Add textual content
my $text = $page->text();
# Add graphical content (paths and shapes)
my $canvas = $page->graphics();
METHODS
size
# Set the page size using a common name
$page->size('letter');
# Set the page size using coordinates in points (X1, Y1, X2, Y2)
$page->size([0, 0, 612, 792]);
# Get the page coordinates in points
my @rectangle = $page->size();
Set the physical page size (a.k.a. media box) when called with an argument. See "Page
Sizes" below for possible values. Returns the $page object.
Returns the coordinates of the rectangle enclosing the physical page size when called
without arguments.
The size method is a convenient shortcut for setting the PDF's media box when print-
related page boundaries aren't required. It's equivalent to the following:
# Set
$page = $page->boundaries(media => $size);
# Get
@rectangle = $page->boundaries->{'media'}->@*;
boundaries
# Set
$page->boundaries(
media => '13x19',
bleed => [0.75 * 72, 0.75 * 72, 12.25 * 72, 18.25 * 72],
trim => 0.25 * 72,
);
# Get
%boundaries = $page->boundaries();
($x1, $y1, $x2, $y2) = $page->boundaries('trim');
Set prepress page boundaries when called with a hash containing one or more page boundary
definitions. Returns the $page object.
Returns the current page boundaries if called without arguments. Returns the coordinates
for the specified page boundary if called with one argument.
Page Boundaries
PDF defines five page boundaries. When creating PDFs for print shops, you'll most
commonly use just the media box and trim box. Traditional print shops may also use the
bleed box when adding printer's marks and other information.
o media
The media box defines the boundaries of the physical medium on which the page is to be
printed. It may include any extended area surrounding the finished page for bleed,
printing marks, or other such purposes. The default value is a US letter page (8.5" x
11").
o crop
The crop box defines the region to which the contents of the page shall be clipped
(cropped) when displayed or printed. The default value is the page's media box.
This is a historical page boundary. You'll likely want to set the bleed and/or trim
boxes instead.
o bleed
The bleed box defines the region to which the contents of the page shall be clipped
when output in a production environment. This may include any extra bleed area needed
to accommodate the physical limitations of cutting, folding, and trimming equipment.
The actual printed page (media box) may include printing marks that fall outside the
bleed box. The default value is the page's crop box.
o trim
The trim box defines the intended dimensions of the finished page after trimming. It
may be smaller than the media box to allow for production-related content, such as
printing instructions, cut marks, or color bars. The default value is the page's crop
box.
o art
The art box defines the extent of the page's meaningful content (including potential
white space) as intended by the page's creator. The default value is the page's crop
box.
Page Sizes
PDF page sizes are stored as rectangle coordinates. For convenience, PDF::API2 also
supports a number of aliases and shortcuts that are more human-friendly.
The following formats are available:
o a standard paper size
$page->boundaries(media => 'A4');
Aliases for the most common paper sizes are built in (case-insensitive).
US: Letter, Legal, Ledger, Tabloid
Metric: 4A0, 2A0, A0 - A6, 4B0, 2B0, and B0 - B6
o a "WxH" string in inches
$page->boundaries(media => '8.5x11');
Many US paper sizes are commonly identified by their size in inches rather than by a
particular name. These can be passed as strings with the width and height separated
by an "x".
Examples: "4x6", "12x18", "8.5x11"
o a number (in points) representing a reduction from the next-larger box
# Note: There are 72 points per inch
$page->boundaries(media => '12x18', trim => 0.5 * 72);
# Equivalent
$page->boundaries(media => [0, 0, 12 * 72, 18 * 72],
trim => [0.5 * 72, 0.5 * 72, 11.5 * 72, 17.5 * 72]);
This example shows a 12" x 18" physical sheet that will be reduced to a final size of
11" x 17" by trimming 0.5" from each edge. The smaller boundary is assumed to be
centered on the larger one.
The "next-larger box" follows this order, stopping at the first defined value:
art -> trim -> bleed -> media
crop -> media
This option isn't available for the media box since it is by definition the largest
boundary.
o [$width, $height] in points
$page->boundaries(media => [8.5 * 72, 11 * 7.2]);
For other page or boundary sizes, the width and height (in points) can be given
directly as an array.
o [$x1, $y1, $x2, $y2] in points
$page->boundaries(media => [0, 0, 8.5 * 72, 11 * 72]);
Finally, the raw coordinates of the bottom-left and top-right corners of a rectangle
can be specified.
rotation
$page = $page->rotation($degrees);
Rotates the page clockwise when displayed or printed. $degrees must be a multiple of 90
and may be negative for counter-clockwise rotation.
The coordinate system follows the page rotation. In other words, after rotating the page
180 degrees, [0, 0] will be in the top right corner of the page rather than the bottom
left, X will increase to the right, and Y will increase downward.
To create a landscape page without moving the origin, use "size".
graphics
my $canvas = $page->graphics(%options);
Returns a PDF::API2::Content object for drawing paths and shapes.
The following options are available:
o prepend (boolean)
If true, place the drawing at the beginning of the page's content stream instead of
the end.
o compress (boolean)
Manually specify whether the drawing instructions should be compressed. If
unspecified, the PDF's compression setting will be used, which is on by default.
text
my $text = $page->text(%options);
Returns a PDF::API2::Content object for including textual content.
The options are the same as the "graphics" method.
object
$page = $page->object($object, $x, $y, $scale_x, $scale_y);
Places an image or other external object (a.k.a. XObject) on the page in the specified
location.
For images, $scale_x and $scale_y represent the width and height of the image on the page
in points. If $scale_x is omitted, it will default to 72 pixels per inch. If $scale_y is
omitted, the image will be scaled proportionally based on the image dimensions.
For other external objects, the scale is a multiplier, where 1 (the default) represents
100% (i.e. no change).
If the object to be placed depends on a coordinate transformation (e.g. rotation or skew),
first create a content object using "graphics", then call "object" in PDF::API2::Content
after making the appropriate transformations.
annotation
my $annotation = $page->annotation();
Returns a new PDF::API2::Annotation object.
MIGRATION
See "MIGRATION" in PDF::API2 for an overview.
gfx Replace with "graphics".
rotate
Replace with "rotation".
mediabox
get_mediabox
Replace with "size" if not in a print shop environment or "boundaries" if more complex
page boundaries are needed.
If using page size aliases (e.g. "letter" or "A4"), check the Page Sizes section to
ensure that the alias you're using is still supported (you'll get an error if it
isn't).
cropbox
bleedbox
trimbox
artbox
get_cropbox
get_bleedbox
get_trimbox
get_artbox
Replace with "boundaries".
