=head1 NAME
|
|
|
|
C4::Labels::Label - A class for creating and manipulating label objects in Koha
|
|
|
|
=head1 ABSTRACT
|
|
|
|
This module provides methods for creating, and otherwise manipulating single label objects used by Koha to create and export labels.
|
|
|
|
=head1 METHODS
|
|
|
|
=head2 new()
|
|
|
|
Invoking the I<new> method constructs a new label object containing the supplied values. Depending on the final output format of the label data
|
|
the minimal required parameters change. (See the implimentation of this object type in labels/label-create-pdf.pl and labels/label-create-csv.pl
|
|
and labels/label-create-xml.pl for examples.) The following parameters are optionally accepted as key => value pairs:
|
|
|
|
C<batch_id> Batch id with which this label is associated
|
|
C<item_number> Item number of item to be the data source for this label
|
|
C<height> Height of this label (All measures passed to this method B<must> be supplied in postscript points)
|
|
C<width> Width of this label
|
|
C<top_text_margin> Top margin of this label
|
|
C<left_text_margin> Left margin of this label
|
|
C<barcode_type> Defines the barcode type to be used on labels. NOTE: At present only the following barcode types are supported in the label creator code:
|
|
|
|
=over 9
|
|
|
|
=item .
|
|
CODE39 = Code 3 of 9
|
|
|
|
=item .
|
|
CODE39MOD = Code 3 of 9 with modulo 43 checksum
|
|
|
|
=item .
|
|
CODE39MOD10 = Code 3 of 9 with modulo 10 checksum
|
|
|
|
=item .
|
|
COOP2OF5 = A varient of 2 of 5 barcode based on NEC's "Process 8000" code
|
|
|
|
=item .
|
|
INDUSTRIAL2OF5 = The standard 2 of 5 barcode (a binary level bar code developed by Identicon Corp. and Computer Identics Corp. in 1970)
|
|
|
|
=back
|
|
|
|
C<printing_type> Defines the general layout to be used on labels. NOTE: At present there are only five printing types supported in the label creator code:
|
|
|
|
=over 9
|
|
|
|
=item .
|
|
BIB = Only the bibliographic data is printed
|
|
|
|
=item .
|
|
BARBIB = Barcode proceeds bibliographic data
|
|
|
|
=item .
|
|
BIBBAR = Bibliographic data proceeds barcode
|
|
|
|
=item .
|
|
ALT = Barcode and bibliographic data are printed on alternating labels
|
|
|
|
=item .
|
|
BAR = Only the barcode is printed
|
|
|
|
=back
|
|
|
|
C<guidebox> Setting this to '1' will result in a guide box being drawn around the labels marking the edge of each label
|
|
C<font> Defines the type of font to be used on labels. NOTE: The following fonts are available by default on most systems:
|
|
|
|
=over 9
|
|
|
|
=item .
|
|
TR = Times-Roman
|
|
|
|
=item .
|
|
TB = Times Bold
|
|
|
|
=item .
|
|
TI = Times Italic
|
|
|
|
=item .
|
|
TBI = Times Bold Italic
|
|
|
|
=item .
|
|
C = Courier
|
|
|
|
=item .
|
|
CB = Courier Bold
|
|
|
|
=item .
|
|
CO = Courier Oblique (Italic)
|
|
|
|
=item .
|
|
CBO = Courier Bold Oblique
|
|
|
|
=item .
|
|
H = Helvetica
|
|
|
|
=item .
|
|
HB = Helvetica Bold
|
|
|
|
=item .
|
|
HBO = Helvetical Bold Oblique
|
|
|
|
=back
|
|
|
|
C<font_size> Defines the size of the font in postscript points to be used on labels
|
|
C<callnum_split> Setting this to '1' will enable call number splitting on labels
|
|
C<text_justify> Defines the text justification to be used on labels. NOTE: The following justification styles are currently supported by label creator code:
|
|
|
|
=over 9
|
|
|
|
=item .
|
|
L = Left
|
|
|
|
=item .
|
|
C = Center
|
|
|
|
=item .
|
|
R = Right
|
|
|
|
=back
|
|
|
|
C<format_string> Defines what fields will be printed and in what order they will be printed on labels. These include any of the data fields that may be mapped
|
|
to your MARC frameworks. Specify MARC subfields as a 4-character tag-subfield string: ie. 254a Enclose a whitespace-separated list of fields
|
|
to concatenate on one line in double quotes. ie. "099a 099b" or "itemcallnumber barcode" Static text strings may be entered in single-quotes:
|
|
ie. 'Some static text here.'
|
|
C<text_wrap_cols> Defines the column after which the text will wrap to the next line.
|
|
|
|
=head2 get_label_type()
|
|
|
|
Invoking the I<get_label_type> method will return the printing type of the label object.
|
|
|
|
example:
|
|
C<my $label_type = $label->get_label_type();>
|
|
|
|
=head2 get_attr($attribute)
|
|
|
|
Invoking the I<get_attr> method will return the value of the requested attribute or -1 on errors.
|
|
|
|
example:
|
|
C<my $value = $label->get_attr($attribute);>
|
|
|
|
=head2 create_label()
|
|
|
|
Invoking the I<create_label> method generates the text for that label and returns it as an arrayref of an array contianing the formatted text as well as creating the barcode
|
|
and writing it directly to the pdf stream. The handling of the barcode is not quite good OO form due to the linear format of PDF::Reuse::Barcode. Be aware that the instantiating
|
|
code is responsible to properly format the text for insertion into the pdf stream as well as the actual insertion.
|
|
|
|
example:
|
|
my $label_text = $label->create_label();
|
|
|
|
=head2 draw_label_text()
|
|
|
|
Invoking the I<draw_label_text> method generates the label text for the label object and returns it as an arrayref of an array containing the formatted text. The same caveats
|
|
apply to this method as to C<create_label()>. This method accepts the following parameters as key => value pairs: (NOTE: The unit is the postscript point - 72 per inch)
|
|
|
|
C<llx> The lower-left x coordinate for the text block (The point of origin for all PDF's is the lower left of the page per ISO 32000-1)
|
|
C<lly> The lower-left y coordinate for the text block
|
|
C<top_text_margin> The top margin for the text block.
|
|
C<line_spacer> The number of pixels between text rows (This is actually leading: baseline to baseline minus font size. Recommended starting point is 20% of font size)
|
|
C<font> The font to use for this label. See documentation on the new() method for supported fonts.
|
|
C<font_size> The font size in points to use for this label.
|
|
C<justify> The style of justification to use for this label. See documentation on the new() method for supported justification styles.
|
|
|
|
example:
|
|
C<my $label_text = $label->draw_label_text(
|
|
llx => $text_llx,
|
|
lly => $text_lly,
|
|
top_text_margin => $label_top_text_margin,
|
|
line_spacer => $text_leading,
|
|
font => $text_font,
|
|
font_size => $text_font_size,
|
|
justify => $text_justification,
|
|
);>
|
|
|
|
=head2 barcode()
|
|
|
|
Invoking the I<barcode> method generates a barcode for the label object and inserts it into the current pdf stream. This method accepts the following parameters as key => value
|
|
pairs (C<barcode_data> is optional and omitting it will cause the barcode from the current item to be used. C<barcode_type> is also optional. Omission results in the barcode
|
|
type of the current template being used.):
|
|
|
|
C<llx> The lower-left x coordinate for the barcode block (The point of origin for all PDF's is the lower left of the page per ISO 32000-1)
|
|
C<lly> The lower-left y coordinate for the barcode block
|
|
C<width> The width of the barcode block
|
|
C<y_scale_factor> The scale factor to be applied to the y axis of the barcode block
|
|
C<barcode_data> The data to be encoded in the barcode
|
|
C<barcode_type> The barcode type (See the C<new()> method for supported barcode types)
|
|
|
|
example:
|
|
C<$label->barcode(
|
|
llx => $barcode_llx,
|
|
lly => $barcode_lly,
|
|
width => $barcode_width,
|
|
y_scale_factor => $barcode_y_scale_factor,
|
|
barcode_data => $barcode,
|
|
barcode_type => $barcodetype,
|
|
);>
|
|
|
|
=head2 csv_data()
|
|
|
|
Invoking the I<csv_data> method returns an arrayref of an array containing the label data suitable for passing to Text::CSV_XS->combine() to produce csv output.
|
|
|
|
example:
|
|
C<my $csv_data = $label->csv_data();>
