615 C4::Labels::Label - A class for creating and manipulating label objects in Koha
619 This module provides methods for creating, and otherwise manipulating single label objects used by Koha to create and export labels.
625 Invoking the I<new> method constructs a new label object containing the supplied values. Depending on the final output format of the label data
626 the minimal required parameters change. (See the implimentation of this object type in labels/label-create-pdf.pl and labels/label-create-csv.pl
627 and labels/label-create-xml.pl for examples.) The following parameters are optionally accepted as key => value pairs:
629 C<batch_id> Batch id with which this label is associated
630 C<item_number> Item number of item to be the data source for this label
631 C<height> Height of this label (All measures passed to this method B<must> be supplied in postscript points)
632 C<width> Width of this label
633 C<top_text_margin> Top margin of this label
634 C<left_text_margin> Left margin of this label
635 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:
643 CODE39MOD = Code 3 of 9 with modulo 43 checksum
646 CODE39MOD10 = Code 3 of 9 with modulo 10 checksum
649 COOP2OF5 = A variant of 2 of 5 barcode based on NEC's "Process 8000" code
652 INDUSTRIAL2OF5 = The standard 2 of 5 barcode (a binary level bar code developed by Identicon Corp. and Computer Identics Corp. in 1970)
655 EAN13 = The standard EAN-13 barcode
659 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:
664 BIB = Only the bibliographic data is printed
667 BARBIB = Barcode proceeds bibliographic data
670 BIBBAR = Bibliographic data proceeds barcode
673 ALT = Barcode and bibliographic data are printed on alternating labels
676 BAR = Only the barcode is printed
680 C<guidebox> Setting this to '1' will result in a guide box being drawn around the labels marking the edge of each label
681 C<font> Defines the type of font to be used on labels. NOTE: The following fonts are available by default on most systems:
695 TBI = Times Bold Italic
704 CO = Courier Oblique (Italic)
707 CBO = Courier Bold Oblique
716 HBO = Helvetical Bold Oblique
720 C<font_size> Defines the size of the font in postscript points to be used on labels
721 C<callnum_split> Setting this to '1' will enable call number splitting on labels
722 C<text_justify> Defines the text justification to be used on labels. NOTE: The following justification styles are currently supported by label creator code:
737 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
738 to your MARC frameworks. Specify MARC subfields as a 4-character tag-subfield string: ie. 254a Enclose a whitespace-separated list of fields
739 to concatenate on one line in double quotes. ie. "099a 099b" or "itemcallnumber barcode" Static text strings may be entered in single-quotes:
740 ie. 'Some static text here.'
741 C<text_wrap_cols> Defines the column after which the text will wrap to the next line.
743 =head2 get_label_type()
745 Invoking the I<get_label_type> method will return the printing type of the label object.
748 C<my $label_type = $label->get_label_type();>
750 =head2 get_attr($attribute)
752 Invoking the I<get_attr> method will return the value of the requested attribute or -1 on errors.
755 C<my $value = $label->get_attr($attribute);>
757 =head2 create_label()
759 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
760 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
761 code is responsible to properly format the text for insertion into the pdf stream as well as the actual insertion.
764 my $label_text = $label->create_label();
766 =head2 draw_label_text()
768 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
769 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)
771 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)
772 C<lly> The lower-left y coordinate for the text block
773 C<top_text_margin> The top margin for the text block.
774 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)
775 C<font> The font to use for this label. See documentation on the new() method for supported fonts.
776 C<font_size> The font size in points to use for this label.
777 C<justify> The style of justification to use for this label. See documentation on the new() method for supported justification styles.
780 C<my $label_text = $label->draw_label_text(
783 top_text_margin => $label_top_text_margin,
784 line_spacer => $text_leading,
786 font_size => $text_font_size,
787 justify => $text_justification,
792 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
793 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
794 type of the current template being used.):
796 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)
797 C<lly> The lower-left y coordinate for the barcode block
798 C<width> The width of the barcode block
799 C<y_scale_factor> The scale factor to be applied to the y axis of the barcode block
800 C<barcode_data> The data to be encoded in the barcode
801 C<barcode_type> The barcode type (See the C<new()> method for supported barcode types)
807 width => $barcode_width,
808 y_scale_factor => $barcode_y_scale_factor,
809 barcode_data => $barcode,
810 barcode_type => $barcodetype,
815 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.
818 C<my $csv_data = $label->csv_data();>
