    $page->rotate($deg)

Rotates the page by the given degrees, which must be a multiple of 90. An angle that is not a multiple of 90 will be rounded to the nearest 90 degrees, with a message.

Note that the rotation angle is clockwise for a positive amount! E.g., a rotation of +90 (or -270) will have the bottom edge of the paper at the left of the screen. After rotating the page 180 degrees, "[0, 0]" (originally lower left corner) will be 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.

(This allows you to auto-rotate to landscape without changing the mediabox! There are other ways to accomplish this end, such as using the size() method, which will not change the coordinate system (move the origin).)

Note that some users have reported problems with using "rotate", that the dimensions were limited to the smaller of the original height or width. If you experience this, be sure to check whether you are doing some sort of crop box or other clipping, that might not rotate as expected with the rest of the page. In other words, you might need to manually adjust the crop box dimensions.

Do not confuse this rotate() call with the graphics context rotation (Content.pm) rotate(), which permits any angle, is of opposite direction, and does not shift the origin!

Alternate name: "rotation"

This has been added for PDF::API2 compatibility.

    $page->size($size)  # Set
    @rectangle = $page->size()  # Get

Set the physical page size or return the coordinates of the rectangle enclosing the physical page size. This is an alternate method provided for compatibility with PDF::API2.

    # Set the physical page (media) size using a common size 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();

See Page Sizes below for possible values. The size method is a convenient shortcut for setting the PDF's media box when other prepress (print-related) page boundaries aren't required. It's equivalent to the following:

    # Set
    $page = $page->boundaries('media' => $size);
    # Get
    @rectangle = $page->boundaries()->{'media'}->@*;

    $page = $page->boundaries(%boundaries)
    \%boundaries = $page->boundaries()

Set prepress page boundaries to facilitate printing. Returns the current page boundaries if called without arguments. This is an alternate method provided for compatibility with PDF::API2.

    # Set
    $page->boundaries(
        # 13x19 inch physical sheet size
        'media' => '13x19',
        # sheet content is 11x17 with 0.25" bleed
        'bleed' => [0.75 * 72, 0.75 * 72, 12.25 * 72, 18.25 * 72],
        # 11x17 final trimmed size
        'trim'  => 0.25 * 72,
    );
    # Get
    %boundaries = $page->boundaries();
    ($x1,$y1, $x2,$y2) = $page->boundaries('trim');

The %boundaries hash contains one or more page boundary keys (see Page Boundaries) to set or replace, each with a corresponding size (see Page Sizes).

If called without arguments, the returned hashref will contain (Get) all five boundaries. If called with one string argument, it returns the coordinates for the specified page boundary. If more than one boundary type is given, only the first is processed, and a warning is given that the remainder are ignored.

    $gfx = $page->gfx(%opts)
    $gfx = $page->gfx($prepend)
    $gfx = $page->gfx()

Returns a graphics content object, for drawing paths and shapes.

You may specify the "prepend" flag in the old or new way. The old way is to give a single boolean value (0 false, non-zero true). The new way is to give a hash element named 'prepend', with the same values.

gfx(boolean_value $prepend)

gfx('prepend' => boolean_value)

If $prepend is true, or the option 'prepend' is given with a true value, the content will be prepended to the page description (at the beginning of the page's content stream). Otherwise, it will be appended. The default is false.

gfx('compress' => boolean_value)

You may specify a compression flag saying whether the drawing instructions are to be compressed. If not given, the default is for the overall PDF compression setting to be used (on by default).

You may have more than one gfx object. They and text objects will be output as objects and streams in the order defined, with all actions pertaining to this gfx object appearing in one stream. However, note that graphics and text objects are not fully independent of each other: the exit state (linewidth, strokecolor, etc.) of one object is the entry state of the next object in line to be output, and so on.

If you intermix multiple gfx and text objects on a page, the results may be confusing. Say you have $gfx1, $text1, $gfx2, and $text2 on your page (created in that order). PDF::Builder will output all the $gfx1->action calls in one stream, then all the $text1->action calls in the next stream, and likewise for $gfx2 usage and finally $text2.

Then it's PDF's turn to confuse you. PDF will process the entire $gfx1 object stream, accumulating the graphics state to the end of the stream, and using that as the entry state into $text1. In a similar manner, $gfx2 and $text2 are read, processed, and rendered. Thus, a change in, say, the dash pattern in the middle of $gfx1, after you have output some $gfx2, $text1, and $text2 material, may suddenly show up at the beginning of $text1 (and continue through $gfx2 and $text2)!

It is possible to use multiple graphics objects, to avoid having to change settings constantly, but you may want to consider resetting all your settings at the first call to each object, so that you are starting from a known base. This may most easily be done by using $type->restore() and ->save() just after creating $type:

    $text1 = $page->text(); 
      $text1->save();
    $grfx1 = $page->gfx();
      $grfx1->restore();
      $grfx1->save();
    $text2 = $page->text();
      $text2->restore();
      $text2->save();
    $grfx2 = $page->gfx();
      $grfx1->restore();

Alternate name: "graphics"

This has been added for PDF::API2 compatibility.

    $text = $page->text(%opts)
    $text = $page->text($prepend)
    $text = $page->text()

Returns a text content object, for writing text. See PDF::Builder::Content for details.

You may specify the "prepend" flag in the old or new way. The old way is to give a single boolean value (0 false, non-zero true). The new way is to give a hash element named 'prepend', with the same values.

text(boolean_value $prepend)

text('prepend' => boolean_value)

If $prepend is true, or the option 'prepend' is given with a true value, the content will be prepended to the page description (at the beginning of the page's content stream). Otherwise, it will be appended. The default is false.

text('compress' => boolean_value)

You may specify a compression flag saying whether the text content is to be compressed. If not given, the default is for the overall PDF compression setting to be used (on by default).

Please see the discussion above in gfx() regarding multiple graphics and text objects on one page, how they are grouped into PDF objects and streams, and the rendering consequences of running through one entire object at a time, before moving on to the next.

The text object has many settings and attributes of its own, but shares many with graphics (gfx), such as strokecolor, fillcolor, linewidth, linedash, and the like. Thus there is some overlap in attributes, and graphics and text calls can affect each other.

    $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.

If $x and $y are omitted, the object will be placed at "[0, 0]".

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::Builder::Content after making the appropriate transformations.

    $ant = $page->annotation()

Returns a new annotation object.

    $page->resource($type, $key, $obj)

Adds a resource to the page-inheritance tree.

Example:

    $co->resource('Font', $fontkey, $fontobj);
    $co->resource('XObject', $imagekey, $imageobj);
    $co->resource('Shading', $shadekey, $shadeobj);
    $co->resource('ColorSpace', $spacekey, $speceobj);

Note: You only have to add the required resources if they are NOT handled by the *font*, *image*, *shade* or *space* methods.
