otherwise we simply remove it

=head1 NAME
C4::Patroncards::Lib - A shared library of linear functions used in the Patroncard Creator module in Koha
=head1 ABSTRACT
This library provides functions used by various sections of the Patroncard Creator module.
=head1 FUNCTIONS
=head2 C4::Patroncards::Lib::unpack_UTF8()
This function returns a reference to an array of hex values equivalent to the utf8 values of the string passed in. This assumes, of course, that the string is
indeed utf8.
example:
my $hex = unpack_UTF8($str);
=cut
=head2 C4::Patroncards::Lib::text_alignment()
This function returns $Tx and $Tw values for the supplied text alignment. It accepts six parameters:
C<origin_llx> = the x value for the origin of the text box to align text in
C<text_box_width> = the width in postscript points of the text box
C<text_llx> = the x value for the lower left point of the text to align
C<string_width> = the width in postscript points of the string of text to align
C<line> = the line of text to align (this may be set to 'undef' for all alignment types except 'Justify')
C<alignment> = the type of text alignment desired:
=item .
B<L> Left align
=item .
B<C> Center align
=item .
B<R> Right align
=item .
B<J> Justify
example:
my ($Tx, $Tw) = text_alignment($origin_llx, $text_box_width, $text_llx, $string_width, $line, $alignment);
=cut
=head2 C4::Patroncards::Lib::leading()
This function accepts a single parameter, font postscript point size, and returns the amount of leading to be added.
example:
my $leading = leading($font_size);
=cut
=head2 C4::Patroncards::Lib::box()
This function will create and insert a "guide box" into the supplied pdf object. It accepts five arguments:
C<llx> = the x value of the lower left coordinate of the guide box
C<lly> = the y value of the lower left coordinate of the guide box
C<width> = the width of the guide box
C<height> = the height of the guide box
C<pdf> = the pdf object into which to insert the guide box
example:
box($llx, $lly, $width, $height, $pdf);
=cut
