The header is usually just "I<modulename> p. I<pagenumber>". =item $parser->normal_halfpoint_size( I<halfpoint_integer> ); This method sets the size (in half-points, like 26 for 13-point) that normal paragraphic text will appear in. =item $parser->no_proofing_exemptions( I<true_or_false> ); Set this value to true if you don't want the formatter to try putting a hidden code on all Perl symbols (as best as it can notice them) that labels them as being not in English, and so not worth spellchecking. =item $parser->doc_lang( I<microsoft_decimal_language_code> ) This sets the language code to tag this document as being in. By default, it is currently the value of the environment variable C<RTFDEFLANG>, or if that's not set, then the value 1033 (for US English). Setting this appropriately is useful if you want to use the RTF to spellcheck, and/or if you want it to hyphenate right. Here are some notable values: 1033 US English 2057 UK English 3081 Australia English 4105 Canada English 1034 Spain Spanish 2058 Mexico Spanish 1031 Germany German 1036 France French 3084 Canada French 1035 Finnish 1044 Norwegian (Bokmal) 2068 Norwegian (Nynorsk) =back If you are particularly interested in customizing this module's output even more, see the source and/or write to me. =head1 SEE ALSO L<Pod::Simple>, L<RTF::Writer>, L<RTF::Cookbook>, L<RTF::Document>, L<RTF::Generator> =head1 SUPPORT Questions or discussion about POD and Pod::Simple should be sent to the pod-people@perl.org mail list.

=head1 NAME

Pod::Simple::RTF -- format Pod as RTF

=head1 SYNOPSIS

perl -MPod::Simple::RTF -e \
   "exit Pod::Simple::RTF->filter(shift)->any_errata_seen" \
   thingy.pod > thingy.rtf

=head1 DESCRIPTION

This class is a formatter that takes Pod and renders it as RTF, good for
viewing/printing in MSWord, WordPad/write.exe, TextEdit, etc.

This is a subclass of L<Pod::Simple> and inherits all its methods.

=head1 FORMAT CONTROL ATTRIBUTES

You can set these attributes on the parser object before you
call C<parse_file> (or a similar method) on it:

=over

=item $parser->head1_halfpoint_size( I<halfpoint_integer> );

=item $parser->head2_halfpoint_size( I<halfpoint_integer> );

=item $parser->head3_halfpoint_size( I<halfpoint_integer> );

=item $parser->head4_halfpoint_size( I<halfpoint_integer> );

These methods set the size (in half-points, like 52 for 26-point)
that these heading levels will appear as.

=item $parser->codeblock_halfpoint_size( I<halfpoint_integer> );

This method sets the size (in half-points, like 21 for 10.5-point)
that codeblocks ("verbatim sections") will appear as.

=item $parser->header_halfpoint_size( I<halfpoint_integer> );

This method sets the size (in half-points, like 15 for 7.5-point)
that the header on each page will appear in.  The header
is usually just "I<modulename> p. I<pagenumber>".

=item $parser->normal_halfpoint_size( I<halfpoint_integer> );

This method sets the size (in half-points, like 26 for 13-point)
that normal paragraphic text will appear in.

=item $parser->no_proofing_exemptions( I<true_or_false> );

Set this value to true if you don't want the formatter to try
putting a hidden code on all Perl symbols (as best as it can
notice them) that labels them as being not in English, and
so not worth spellchecking.

=item $parser->doc_lang( I<microsoft_decimal_language_code> )

This sets the language code to tag this document as being in. By
default, it is currently the value of the environment variable
C<RTFDEFLANG>, or if that's not set, then the value
1033 (for US English).

Setting this appropriately is useful if you want to use the RTF
to spellcheck, and/or if you want it to hyphenate right.

Here are some notable values:

1033  US English
  2057  UK English
  3081  Australia English
  4105  Canada English
  1034  Spain Spanish
  2058  Mexico Spanish
  1031  Germany German
  1036  France French
  3084  Canada French
  1035  Finnish
  1044  Norwegian (Bokmal)
  2068  Norwegian (Nynorsk)
