6 PDF::API2::NamedDestination - Add named destinations (views) to a PDF
7
9 new
10 $destination = PDF::API2::NamedDestination->new($pdf, ...);
11
12 Creates a new named destination object. If any additional arguments
13 are present, they will be passed to "destination()".
14
15 destination
16 $destination = $destination->destination($page, $location, @args);
17
18 A destination is a particular view of a PDF, consisting of a page
19 object, the location of the window on that page, and possible
20 coordinate and zoom arguments.
21
22 # The XYZ location takes three arguments
23 my $dest1 = PDF::API2::NamedDestination->new($pdf);
24 $dest->destination($pdf->open_page(1), 'xyz' => ($x, $y, $zoom));
25
26 # The Fit location doesn't require any arguments
27 my $dest2 = PDF::API2::NamedDestination->new($pdf);
28 $dest->destination($pdf->open_page(2), 'fit');
29
30 The following locations are available:
31
32 • xyz ($left, $top, $zoom)
33
34 Display the page with the coordinates ($left, $top) positioned at
35 the upper-left corner of the window and the contents of the page
36 magnified by the factor $zoom. An "undef" value for any of the
37 arguments specifies that the current value of that argument shall
38 be retained unchanged. A zoom factor of 0 has the same meaning as
39 "undef".
40
41 • fit
42
43 Display the page with its contents magnified just enough to fit the
44 entire page within the window both horizontally and vertically. If
45 the required horizontal and vertical magnification factors are
46 different, use the smaller of the two, centering the page within
47 the window in the other dimension.
48
49 • fith ($top)
50
51 Display the page with the vertical coordinate $top positioned at
52 the top edge of the window and the contents of the page magnified
53 just enough to fit the entire width of the page within the window.
54 An "undef" value for $top specifies that the current value of that
55 argument shall be retained unchanged.
56
57 • fitv ($left)
58
59 Display the page with the horizontal coordinate $left positioned at
60 the left edge of the window and the contents of the page magnified
61 just enough to fit the entire height of the page within the window.
62 An "undef" value for $left specifies that the current value of that
63 argument shall be retained unchanged.
64
65 • fitr ($left, $bottom, $right, $top)
66
67 Display the page with its contents magnified just enough to fit the
68 rectangle specified by the coordinates $left, $bottom, $right, and
69 $top entirely within the window both horizontally and vertically.
70 If the required horizontal and vertical magnification factors are
71 different, use the smaller of the two, centering the rectangle
72 within the window in the other dimension.
73
74 • fitb
75
76 Display the page with its contents magnified just enough to fit its
77 bounding box entirely within the window both horizontally and
78 vertically. If the required horizontal and vertical magnification
79 factors are different, use the smaller of the two, centering the
80 bounding box within the window in the other dimension.
81
82 • fitbh ($top)
83
84 Display the page with the vertical coordinate $top positioned at
85 the top edge of the window and the contents of the page magnified
86 just enough to fit the entire width of its bounding box within the
87 window. An "undef" value for $top specifies that the current value
88 of that argument shall be retained unchanged.
89
90 • fitbv ($left)
91
92 Display the page with the horizontal coordinate $left positioned at
93 the left edge of the window and the contents of the page magnified
94 just enough to fit the entire height of its bounding box within the
95 window. An "undef" value for $left specifies that the current
96 value of that argument shall be retained unchanged.
97
98 goto
99 $destination = $destination->goto($page, $location, @args);
100
101 A go-to action changes the view to a specified destination (page,
102 location, and magnification factor).
103
104 Parameters are as described in "destination".
105
106 uri
107 $destination = $destination->uri($uri);
108
109 A URI action indicates that a URI -- typically a web page -- should be
110 launched.
111
112 launch
113 $destination = $destination->launch($file);
114
115 A launch action runs an application or opens or prints a document.
116
117 $file contains the path to the application to be launched or the
118 document to be opened or printed.
119
120 pdf
121 $destination = $destination->pdf($file, $page_number, $location, @args);
122
123 Similar to "goto", but the destination is in a different PDF file
124 located at $file. $page_number is an integer rather than a page
125 object, and the other parameters are as described in "destination".
