HTML::FormatRTF(3)					User Contributed Perl Documentation					HTML::FormatRTF(3)

NAME
HTML::FormatRTF - Format HTML as RTF VERSION
version 2.11 SYNOPSIS
use HTML::FormatRTF; my $out_file = "test.rtf"; open(RTF, ">$out_file") or die "Can't write-open $out_file: $! Aborting"; print RTF HTML::FormatRTF->format_file( 'test.html', 'fontname_headings' => "Verdana", ); close(RTF); DESCRIPTION
HTML::FormatRTF is a class for objects that you use to convert HTML to RTF. There is currently no proper support for tables or forms. This is a subclass of HTML::Formatter, whose documentation you should consult for more information on underlying methods such as "new", "format", "format_file" etc You can specify any of the following parameters in the call to "new", "format_file", or "format_string": lm Amount of extra indenting to apply to the left margin, in twips (twentieths of a point). Default is 0. So if you wanted the left margin to be an additional half inch larger, you'd set "lm => 720" (since there's 1440 twips in an inch). If you wanted it to be about 1.5cm larger, you'd set "lw => 850" (since there's about 567 twips in a centimeter). rm Amount of extra indenting to apply to the left margin, in twips (twentieths of a point). Default is 0. normal_halfpoint_size This is the size of normal text in the document, in half-points. The default value is 22, meaning that normal text is in 11 point. header_halfpoint_size This is the size of text used in the document's page-header, in half-points. The default value is 17, meaning that normal text is in 7.5 point. Currently, the header consists just of "p.pagenumber" in the upper-right-hand corner, and cannot be disabled. head1_halfpoint_size ... head6_halfpoint_size These control the font size of each heading level, in half-twips. For example, the default for head3_halfpoint_size is 25, meaning that HTML "<h3>...</h3>" text will be in 12.5 point text (in addition to being underlined and in the heading font). codeblock_halfpoint_size This controls the font size (in half-points) of the text used for "<pre>...</pre>" text. By default, it is 18, meaning 9 point. fontname_body This option controls what font is to be used for the body of the text -- that is, everything other than heading text and text in pre/code/tt elements. The default value is currently "Times". Other handy values I can suggest using are "Georgia" or "Bookman Old Style". fontname_code This option controls what font is to be used for text in pre/code/tt elements. The default value is currently "Courier New". fontname_headings This option controls what font name is to be used for headings. You can use the same font as fontname_body, but I prefer a sans-serif font, so the default value is currently "Arial". Also consider "Tahoma" and "Verdana". document_language This option controls what Microsoft language number will be specified as the language for this document. The current default value is 1033, for US English. Consult an RTF reference for other language numbers. hr_width This option controls how many underline characters will be used for rendering a "<hr>" tag. Its default value is currently 50. You can usually leave this alone, but under some circumstances you might want to use a smaller or larger number. no_prolog If this option is set to a true value, HTML::FormatRTF will make a point of not emitting the RTF prolog before the document. By default, this is off, meaning that HTML::FormatRTF will emit the prolog. This option is of interest only to advanced users. no_trailer If this option is set to a true value, HTML::FormatRTF will make a point of not emitting the RTF trailer at the end of the document. By default, this is off, meaning that HTML::FormatRTF will emit the bit of RTF that ends the document. This option is of interest only to advanced users. SEE ALSO
