	Creates a new pdf report object.
        If no %opts are specified the module
        will use the factory defaults.

	my $pdf = new PDF::Report(PageSize => "letter",
                                  PageOrientation => "Landscape");

        my $pdf = new PDF::Report(File => $file);

PDF::API2 Removes all space between every word in the string you pass
and then rejoins each word with one space.  If you want to use a string with
more than one space between words for formatting purposes, you can either use
the hack below or change PDF::API2 (that's what I did ;).  The code below may
or may not work according to what font you are using.  I used 2 \xA0 per space
because that worked for the Helvetica font I was using.

B<To use a fixed width string with more than one space between words, you can do something like:>

    sub replaceSpace {
      my $text = shift;
      my $nbsp = "\xA0";
      my $new = '';
      my @words = split(/ /, $text);
      foreach my $word (@words) {
        if (length($word)) {
          $new.=$word . ' ';
        } else {
          $new.=$nbsp . $nbsp;
        }
      }
      chop($new);
      return $new;
    }

=head2 setAddTextPos

$pdf->setAddTextPos($hPos, $vPos);

Set the position on the page.  Used by the addText function.

=cut

sub setAddTextPos {
  my ($self, $hPos, $vPos) = @_;
  $self->{hPos}=$hPos;
  $self->{vPos}=$vPos;
}

=head2 getAddTextPos

($hPos, $vPos) = $pdf->getAddTextPos();

Return the (x, y) value of the text position.

=cut

sub getAddTextPos {
  my ($self) = @_;
  return($self->{hPos}, $self->{vPos});
}

=head2 setAlign

$pdf->setAlign($align);

Set the justification of the text.  Used by the addText function.

=cut

sub setAlign {
  my $self = shift;
  my $align = lc(shift);

  if ($align=~m/^left$|^right$|^center$/) {
    $self->{align}=$align;
    $self->{hPos}=undef;        # Clear addText()'s tracking of hPos
  }
}

=head2 getAlign

$align = $pdf->getAlign();

Returns the text justification.

=cut

sub getAlign {
  my $self= shift @_;
  return($self->{align});
}

=head2 wrapText

$newtext = $pdf->wrapText($text, $width);

This is a helper function called by addText, which can be called by itself.
wrapText() wraps $text within $width.

=cut

sub wrapText {
  my $self = shift;
  my $text = shift;
  my $width = shift;

  $text = '' if !length($text);

  return $text if ($text =~ /\n/);  # We don't wrap text with carriage returns
  return $text unless defined $width;  # If no width was specified, return text

  my $txt = $self->{page}->text;
  $txt->font($self->{font}, $self->{size});

  my $ThisTextWidth=$txt->advancewidth($text);
  return $text if ( $ThisTextWidth <= $width);

  my $widSpace = $txt->advancewidth('t');  # 't' closest width to a space

  my $currentWidth = 0;
  my $newText = "";
  foreach ( split / /, $text ) {
    my $strWidth = $txt->advancewidth($_);
    if ( ( $currentWidth + $strWidth ) > $width ) {
      $currentWidth = $strWidth + $widSpace;
      $newText .= "\n$_ ";
    } else {
      $currentWidth += $strWidth + $widSpace;
      $newText .= "$_ ";
    }
  }

  return $newText;
}

=head2 addText

$pdf->addText($text, $hPos, $textWidth, $textHeight);

Takes $text and prints it to the current page at $hPos.  You may just want
to pass this function $text if the text is "pre-wrapped" and setAddTextPos
has been called previously.  Pass a $hPos to change the position the text
will be printed on the page.  Pass a  $textWidth and addText will wrap the
text for you.  $textHeight controls the row height.

=head2 addParagraph

$pdf->addParagraph($text, $hPos, $vPos, $width, $height, $indent, $lead);

This is really not that complicated, trust me! ;) I am pretty unfamiliar with
barcode lingo and types so if I get any of this wrong, lemme know!
This is a very flexible way to draw a barcode on your PDF document.
$x and $y represent the center of the barcode's position on the document.
$scale is the size of the entire barcode 1 being 1:1, which is all you'll
need most likely.  $type is the type of barcode which can be codabar, 2of5int,
3of9, code128, or ean13.  $code is the alpha-numeric code which the barcode
will represent.  $extn is the
extension to the $code, where applicable.  $umzn is the upper mending zone and
$lmzn is the lower mending zone. $zone is the the zone or height of the bars.
$quzn is the quiet zone or the space between the frame and the barcode.  $spcr
is what to put between each number/character in the text.  $ofwt is the
overflow width.  $fnsz is the fontsize used for the text.  $text is optional
text beneathe the barcode.
