NAME
       GD::Text::Wrap -	Wrap strings in	boxes

SYNOPSIS
	 use GD;
	 use GD::Text::Wrap;

	 my $gd	= GD::Image->new(800,600);
	 # allocate colours, do	other things.

	 my $text = <<EOSTR;
	 Lorem ipsum dolor sit amet, consectetuer adipiscing elit,
	 sed diam nonummy nibh euismod tincidunt ut laoreet dolore
	 magna aliquam erat volutpat.
	 EOSTR

	 my $wrapbox = GDTextWrap->new(	$gd,
	     line_space	 => 4,
	     color	 => $black,
	     text	 => $text,
	 );
	 $wrapbox->set_font(gdMediumBoldFont);
	 $wrapbox->set_font('arial', 12);
	 $wrapbox->set(align =>	'left',	width => 120);
	 $wrapbox->draw(10,140);

	 $gd->rectangle($wrap_box->get_bounds(10,140), $color);

DESCRIPTION
       GD::Text::Wrap provides an object that draws a formatted	paragraph of
       text in a box on	a GD::Image canvas, using either a builtin GD font or
       a TrueType font.

METHODS
       This class doesn't inherit from GD::Text	directly, but delegates	most
       of its work to it (in fact to a GD::Text::Align object. That means that
       most of the GD::Text::Align methods are available for this class,
       specifically "set_font" and "font_path".	Other methods and methods with
       a different interface are described here:

   GD::Text::Wrap->new(	$gd_object, attribute => value,	... )
       Create a	new object. The	first argument to new has to be	a valid
       GD::Image object. The other arguments will be passed to the set()
       method for initialisation of the	attributes.

   $wrapbox->set( attribute => value, ... )
       set the value for an attribute. Valid attributes	are:

       width
	   The width of	the box	to draw	the text in. If	unspecified, they will
	   default to the width	of the GD::Image object.

       line_space
	   The number of pixels	between	lines. Defaults	to 2.

       para_space, paragraph_space
	   The number of extra pixels between paragraphs, above	line_space.
	   Defaults to 0.

       color, colour
	   Synonyms. The colour	to use when drawing the	font. Will be
	   initialised to the last colour in the GD object's palette.

       align, alignment
	   Synonyms. One of 'justified'	(the default), 'left', 'right' or
	   'center'.

       text
	   The text to draw. This is the only attribute	that you absolutely
	   have	to set.

       preserve_nl
	   If set to a true value, newlines in the text	will cause a line
	   break.  Note	that lines will	still be justified. If only one	word
	   appears on the line,	it could get ugly.  Defaults to	0.

       As with the methods, attributes unknown to this class get delegated to
       the GD::Text::Align class.

   $wrapbox->get( attribute );
       Get the current value of	an attribute. All attributes mentioned under
       the "set()" method can be retrieved

   $wrapbox->get_bounds()
       Returns the bounding box	of the box that	will be	drawn with the current
       attribute settings as a list. The values	returned are the coordinates
       of the upper left and lower right corner.

	       ($left, $top, $right, $bottom) =	$wrapbox->get_bounds();

       Returns an empty	list on	error.

       NOTE: The return	list of	this method may	change in a future
       implementation that allows angled boxes.

   $wrapbox->draw(x, y)
       Draw the	box, with (x,y)	as the top right corner.  Returns the same
       values as the "getbounds()" method.

       NOTE: The return	list of	this method may	change in a future
       implementation that allows angled boxes.

NOTES
       As with all Modules for Perl: Please stick to using the interface. If
       you try to fiddle too much with knowledge of the	internals of this
       module, you may get burned. I may change	them at	any time.

       You can only use	TrueType fonts with version of GD > 1.20, and then
       only if compiled	with support for this. If you attempt to do it anyway,
       you will	get errors.

       Even though this	module lives in	the GD::Text namespace,	it is not a
       GD::Text. It does however delegate a lot	of its functionality to	a
       contained object	that is	one (GD::Text::Align).

BUGS
       None that I know	of, but	that doesn't mean much.	There may be some
       problems	with exotic fonts, or locales and character encodings that I
       am not used to.

TODO
       Angled boxes.

       At the moment, the only bit of the box that is allowed to be
       unspecified and in fact must be unspecified, is the bottom. If there is
       enough need for it, I might implement more flexibility, in that that
       you need	to only	specify	three of the four sides	of the box, and	the
       fourth will be calculated.

       Automatic resizing of a TrueType	font to	fit inside a box when four
       sides are specified, or maybe some other	nifty things.

       More flexibility	in the interface. Especially draw needs	some thought.

       More and	better error handling.

       Warnings	for lines that are too long and	stick out of the box.  Warning
       for emptyish lines?
