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

|
|
See L for suggestions. |

106
|
|
|
|
|
|
|
|
|
107
|
|
|
|
|
|
|
PDF::Builder can make use of some optional libraries, which are not I |
|
108
|
|
|
|
|
|
|
for a successful installation, but improve speed and capabilities. See |
|
109
|
|

|
L for more information. |

112
|
|
|
|
|
|
|
|
|
113
|
|
|
|
|
|
|
There are some things you should know about character encoding (for text), |
|
114
|
|
|
|
|
|
|
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 |
|
119
|
|
|
|
|
|
|
different ordering of output than intended). See L for more information. |

|

|
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If you need to use this module on a server with an extremely out-of-date version |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. |

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. |

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

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. |

|

|
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. |

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. |
|

|
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. |

|
|
|
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). |

C was formerly known as C (and even before that, |

579

|
|
|
|
|
|
as C), and this older name is still |
|
580
|
|

valid as an alternative to C. It is I that C |
|
581
|
|

|
|
|
|
will be deprecated and then removed some time in the future, so it may be |
|
582
|
|
|
|
|

advisable to use C in new work. |

C was formerly known as C, and this older name is still |

698
|
|
|
|
|
|
|
valid as an alternative to C. It is I that C |
|
699

will be deprecated and then removed some time in the future, so it may be |
|
700

advisable to use C in new work. |

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. |
