NAME
RTF::Document - Perl extension for generating Rich Text (RTF) Files
DESCRIPTION
RTF::Document is a module for generating Rich Text Format (RTF) documents that can be used
by most text converters and word processors.
For a listing of properties, consult the %DOCINFO and %PROPERTIES hashes in the source
code.

EXAMPLE
use RTF::Document;
# Document properties
$rtf = new RTF::Document(
{
doc_page_width => '8.5in',
doc_page_height => '11in'
}
);
# Font definitions
$fAvantGarde = $rtf->add_font ("AvantGarde",
{ family=>swiss,
default=>1
} );
$fCourier = $rtf->add_font ("Courier",
{ family=>monospace, pitch=>fixed,
alternates=>["Courier New", "American Typewriter"]
} );
# Color definitions
$cRed = $rtf->add_color ( { red=>255 } );
$cGreen = $rtf->add_color ( { green=>128 } );
$cCustm = $rtf->add_color ( { red=>0x66, blue=>0x33, green=>0x33 } );
$cBlack = $rtf->add_color ( { name=>'black' } );
$cWhite = $rtf->add_color ( { gray=>'100%' } );
$cNavy = $rtf->add_color ( { blue=>'100%', gray=>'50%' } );
# style definitions
$sNormal = $rtf->add_style( "Normal",
{ font=>$fAvantGarde, font_size=>'12pt',
color_foreground=>$cBlack },
{ type=>paragraph, default=>1 }
);
$sGreen = $rtf->add_style( "Green",
{ color_foreground=>$cGreen },
{ type=>character, additive=>1 }
);
# Mix any combo of properties and text...
$rtf->add_text( $rtf->root(),
"Default text\n\n",
{ bold=>1, underline=>continuous },
"Bold/Underlined Text\n\n",
{ font_size=>'20pt', font=>$fCourier,
color_foreground=>$cRed },
"Bigger, Red and Monospaced.\n\n",
{ style_default=>paragraph },
{ style_default=>character },
"This is ",
[ { style=>$sGreen }, "green" ],
" styled.\n\n"
);
open FILE, ">MyFile.rtf";
binmode FILE;
print FILE $rtf->rtf();
close FILE;
DOCUMENT STRUCTURE
For purposes of using this module, a Rich Text (RTF) Document can be subdivided into
groups. Groups can be considered containers for text and controls (controlling document
and text properties).
For all intents and purposes, a group limits the scope of controls. So if we set the
"bold" character property within a group, the text will be bold only within that group
(until it is turned off within that group).
When generating a RTF document using this module, we are only concerned with the root
group (also called the "Document Area"). (The "Header" groups are taken care of
automatically by this module.)
The Document Area is subdivided into sections. Each section is subdivided into paragraphs.
METHODS
Some of the methods are documented below. (Methods not documented here may be changed in
future versions.)
new
$rtf = new RTF::Document( \%DocumentProperties );
Creates a new RTF document object.
root
$gRoot = $rtf->root();
Returns the "root" group in the RTF document.
new_group
$gMyGroup = $rtf->new_group();
Creates a new group (not inside of the RTF document).
add_group
$gChildOfRoot = $rtf->add_group();
$gChildOfChild = $rtf->add_group( $gChild );
Adds a child group to the specfied group. If no group is specified, the "root" group is
assumed.
$rtf->add_group( $rtf->root(), $gMyGroup );
Adds a group to the specified parent group (in this case, the root group).
add_raw
$rtf->add_raw( $group, '\par', "Some Text" );
Adds raw controls and text to the group. This method is intended for internal use only.
add_text
$rtf->add_text( $group, "Some text ", { bold=>1 }, "more text" );
Adds text and controls to a group. Text is escaped.
add_font
add_color
add_style

KNOWN ISSUES
This module should be considered in the "alpha" stage. Use at your own risk.
There are no default document or style properties produced by this module, with the
exception of the character set. If you want to make sure that a specific font, color, or
style is used, you must specify it. Otherwise you rely on the assumptions of whatever RTF
reader someone is using.
This module does not insert newlines anywhere in the text, even though some RTF writers
break lines before they exceed 225 characters. This may or may not be an issue with some
reader software.
Unknown font or style properties will generally be ignored without warning.
This module supports some newer RTF controls (used in Word 95/Word 97) that may are not
understood by older RTF readers.
Once a Font, Color or Style is added, it cannot be changed. No checking for redundant
entries is done.
Generally, it is not possible to reference a not-yet-created Style with the next or
basedon attributes. However, you can use the constances "last", "self" or "next" to
reference the last style added, the current style being added, or the next style that will
be added, respectively.
Specifying properties in a particular order within a group does not guarantee that they
will be emitted in that order. If order matters, specify them separetly. For instance,
$rtf->add_text($rtf->root, { style_default=>character, bold=>1 } );
should be (if you want to ensure character styles are reset before setting bold text):
$rtf->add_text($rtf->root, { style_default=>character }, { bold=>1 } );
Also note that duplicate properties within the same group won't work. i.e., If you want to
set "style_default" for both paragraphs and characters, you must do so in separate groups.
This isn't so much as a bug as the way Perl handles hashes.
Unimplemented Features
A rather large number of features and control words are not handled in this version. Among
the major features:
Annotations and Comments
Bookmarks
Bullets and Paragraph Numbering
Some support has been added. The backwards-compatability controls for numbered
paragraphs used by older readers has not been added because it is not properly handled
by newer readers.
Character Sets and Internationalization
Non-"ANSI" character sets (i.e., Macintosh) and Unicode character sets are not
supported (at least not intentionally). There is no support for Asian character sets
in this version of the module.
Unicode character escapes are not implemented.
Language codes (defining a default language, or a language for a group of characters)
are not implemented.
Bi-directional and text-flow controls are not implemented.
Embedded Images and OLE Objects
File Tables
Footnotes and Endnotes
Forms
Headers and Footers
Hyphenation Control
Some minimal controls have been added.
Lists and List Tables
Not implemented: List Tables are really a kind of style sheet for lists. Priority
will be given to support generic bullets and paragraph numbering.
Page Numbering
Minimal definition, untested.
Printer Bin Controls
Revision Tables
Special Characters and Document Variables
Most special characters not not implemented, with the exception of tabs. Double
newline characters are converted to a new paragraph control, and single newlines are
converted to a new line control.
Tabs
Tables and Frames
