There are four levels of involvement with PDF::Builder. Depending on what you |
102
|
|
|
|
|
|
|
want to do, different kinds of installs are recommended. |
103
|
|

|

PDF::Builder can make use of some optional libraries, which are not I |
108

|
for a successful installation, but improve speed and capabilities. See |

There are some things you should know about character encoding (for text), |

before you dive in to coding. Please go to L and have a read. |

Invoking "text" and "graphics" methods can lead to unexpected results (a |

122
|
|
|
|
|
|
|
|
123
|
|
|
|
|
|
|
PDF::Builder is mostly PDF 1.4-compliant, but there I complications you |
124
|
|
|
|
|
|
|
should be aware of. Please read L |
125
|
|
|
|
|
|
|
for details. |

=head2 SUPPORTED PERL VERSIONS (BACKWARDS COMPATIBILITY GOALS) |
128
|
|
|
|
|
|
|
|
129
|
|
|
|
|
|
|
PDF::Builder intends to support all major Perl versions that were released in |
130
|
|
|
|
|
|
|
the past six years, plus one, in order to continue working for the life of |
131
|
|
|
|
|
|
|
most long-term-stable (LTS) server distributions. |
132
|
|
|
|
|
|
|
See the L table |
133
|
|
|
|
|
|
|
B x.xxxx0 "Major" release dates. |
134
|
|
|
|
|
|
|
|
135
|
|
|
|
|
|
|
For example, a version of PDF::Builder released on 2018-06-05 would support |
136
|
|
|
|
|
|
|
the last major version of Perl released I 2012-06-05 (5.18), and |
137
|
|
|
|
|
|
|
then one before that, which would be 5.16. Alternatively, the last major |
138
|
|
|
|
|
|
|
version of Perl released I 2012-06-05 is 5.16. |
139
|
|
|
|
|
|
|
|
140
|
|
|
|
|
|
|
The intent is to avoid expending unnecessary effort in supporting very old |
141
|
|
|
|
|
|
|
(obsolete) versions of Perl. |

If you need to use this module on a server with an extremely out-of-date version |
162
|
|
|
|
|
|
|
of Perl, consider using either plenv or Perlbrew to run a newer version of Perl |
163
|
|
|
|
|
|
|
without needing admin privileges. |
164
|
|
|
|
|
|
|
|
165
|
|
|
|
|
|
|
On the other hand, any feature in PDF::Builder should continue to work |
166
|
|
|
|
|
|
|
unchanged for the life of most long-term-stable (LTS) server distributions. |
167
|
|
|
|
|
|
|
Their lifetime is usually about six (6) years. Note that this does B |
168
|
|
|
|
|
|
|
constitute a statement of warranty, but that we I to try to keep any |
169
|
|
|
|
|
|
|
particular release of PDF::Builder working for a period of years. Of course, |
170
|
|
|
|
|
|
|
it helps if you periodically update your Perl installation to something |
171
|
|
|
|
|
|
|
released in the recent past. |

There is a file INFO/KNOWN_INCOMP which lists known incompatibilities with |

|
|
|

|
|
PDF::API2, in case you're thinking of porting over something from that world, |
179
|
|
|
|
|
|
|
or have experience there and want to try PDF::Builder. There is also a file |
180
|
|
|
|
|
|
|
INFO/DEPRECATED, which lists things which are planned to be removed at some |
181
|
|
|

|

|
point. |

The history of PDF::Builder is a complex and exciting saga... OK, it may be |
186
|
|
|
|
|
|
|
mildly interesting. Have a look at L section. |

It is a waste of both your and our time and effort. Open a regular ticket |

(issue), and attach a Perl (.pl) program illustrating the problem, if possible. |

If you believe that you have a program patch, and offer to share it as a PR, we |

may give the go-ahead. Unsolicited PRs may be closed without further action. |

|
If you will be saving it as a file and |
258
|
|
|
|
|
|
|
already know the filename, you can give the 'file' option to minimize |
259
|
|
|
|
|
|
|
possible memory requirements later on (the file is opened immediately for |
260
|
|
|
|
|
|
|
writing, rather than waiting until the C). The C may also be |
261
|
|
|
|
|
|
|
a filehandle. |

=item compress |
264
|
|
|
|
|
|
|
|
265
|
|
|
|
|
|
|
The 'compress' option can be |
266
|
|
|
|
|
|
|
given to specify stream compression: default is 'flate', 'none' (or 0) is no |
267
|
|
|
|
|
|
|
compression. No other compression methods are currently supported. |
268

|
|
|

|
|
=item outver |
270
|
|
|
|
|
|
|
|
271
|
|
|
|
|
|
|
The 'outver' option defaults to 1.4 as the output PDF version and the highest |
272
|
|
|
|
|
|
|
allowed feature version (attempts to use anything higher will give a warning). |
273
|
|
|
|
|
|
|
If an existing PDF with a higher version is read in, C will be |
274
|
|
|
|
|
|
|
increased to that version, with a warning. |
275
|
|
|
|
|
|
|
|
276
|
|
|
|
|
|
|
=item msgver |
277
|
|
|
|
|
|
|
|
278
|
|
|
|
|
|
|
The 'msgver' option value of 1 (default) gives a warning message if the |
279
|
|
|
|
|
|
|
'outver' PDF level has to be bumped up due to either a higher PDF level file |
280
|
|
|
|
|
|
|
being read in, or a higher level feature was requested. A value of 0 |
281
|
|
|
|
|
|
|
suppresses the warning message. |
282
|
|
|
|
|
|
|
|

|
|
|
|
|
|
|
=item diaglevel |
284
|
|
|
|
|
|
|
|
285
|
|
|
|
|
|
|
The 'diaglevel' option can be |
286
|
|
|
|
|
|
|
given to specify the level of diagnostics given by IntegrityCheck(). The |
287
|
|
|
|
|
|
|
default is level 2 (errors and warnings). |
288
|
|

|

B now that C can take a filename as an argument, it effectively |
889

|
|
|
|
|
is interchangeable with C. This is strictly for compatibility with |
890

|
|
|
recent changes to PDF::API2. Unlike PDF::API2, we are not deprecating |
891
|
|
|
|
|
|
|
the C method, because in user interfaces, "save" normally means that |
892
|
|
|
|
|
|
|
the current filename is known and is to be used, while "saveas" normally means |
893
|
|
|
|
|
|
|
that (whether or not there is a current filename) a new filename is to be used. |

Returns a I page object. By default, the page is added to the end |

of the document. If you give an existing page number, the new page |

will be inserted in that position, pushing existing pages back by 1 (e.g., |
1940

C would insert an empty page 5, with the old page 5 now page 6, |
