591 C4::Labels::Label - A class for creating and manipulating label objects in Koha
595 This module provides methods for creating, and otherwise manipulating single label objects used by Koha to create and export labels.
601 Invoking the I<new> method constructs a new label object containing the supplied values. Depending on the final output format of the label data
602 the minimal required parameters change. (See the implimentation of this object type in labels/label-create-pdf.pl and labels/label-create-csv.pl
603 and labels/label-create-xml.pl for examples.) The following parameters are optionally accepted as key => value pairs:
605 C<batch_id> Batch id with which this label is associated
606 C<item_number> Item number of item to be the data source for this label
607 C<height> Height of this label (All measures passed to this method B<must> be supplied in postscript points)
608 C<width> Width of this label
609 C<top_text_margin> Top margin of this label
610 C<left_text_margin> Left margin of this label
611 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:
619 CODE39MOD = Code 3 of 9 with modulo 43 checksum
622 CODE39MOD10 = Code 3 of 9 with modulo 10 checksum
625 COOP2OF5 = A varient of 2 of 5 barcode based on NEC's "Process 8000" code
628 INDUSTRIAL2OF5 = The standard 2 of 5 barcode (a binary level bar code developed by Identicon Corp. and Computer Identics Corp. in 1970)
631 EAN13 = The standard EAN-13 barcode
635 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:
640 BIB = Only the bibliographic data is printed
643 BARBIB = Barcode proceeds bibliographic data
646 BIBBAR = Bibliographic data proceeds barcode
649 ALT = Barcode and bibliographic data are printed on alternating labels
652 BAR = Only the barcode is printed
656 C<guidebox> Setting this to '1' will result in a guide box being drawn around the labels marking the edge of each label
657 C<font> Defines the type of font to be used on labels. NOTE: The following fonts are available by default on most systems:
671 TBI = Times Bold Italic
680 CO = Courier Oblique (Italic)
683 CBO = Courier Bold Oblique
692 HBO = Helvetical Bold Oblique
696 C<font_size> Defines the size of the font in postscript points to be used on labels
697 C<callnum_split> Setting this to '1' will enable call number splitting on labels
698 C<text_justify> Defines the text justification to be used on labels. NOTE: The following justification styles are currently supported by label creator code:
713 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
714 to your MARC frameworks. Specify MARC subfields as a 4-character tag-subfield string: ie. 254a Enclose a whitespace-separated list of fields
715 to concatenate on one line in double quotes. ie. "099a 099b" or "itemcallnumber barcode" Static text strings may be entered in single-quotes:
716 ie. 'Some static text here.'
717 C<text_wrap_cols> Defines the column after which the text will wrap to the next line.
719 =head2 get_label_type()
721 Invoking the I<get_label_type> method will return the printing type of the label object.
724 C<my $label_type = $label->get_label_type();>
726 =head2 get_attr($attribute)
728 Invoking the I<get_attr> method will return the value of the requested attribute or -1 on errors.
731 C<my $value = $label->get_attr($attribute);>
733 =head2 create_label()
735 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
736 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
737 code is responsible to properly format the text for insertion into the pdf stream as well as the actual insertion.
740 my $label_text = $label->create_label();
742 =head2 draw_label_text()
744 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
745 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)
747 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)
748 C<lly> The lower-left y coordinate for the text block
749 C<top_text_margin> The top margin for the text block.
750 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)
751 C<font> The font to use for this label. See documentation on the new() method for supported fonts.
752 C<font_size> The font size in points to use for this label.
753 C<justify> The style of justification to use for this label. See documentation on the new() method for supported justification styles.
756 C<my $label_text = $label->draw_label_text(
759 top_text_margin => $label_top_text_margin,
760 line_spacer => $text_leading,
762 font_size => $text_font_size,
763 justify => $text_justification,
768 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
769 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
770 type of the current template being used.):
772 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)
773 C<lly> The lower-left y coordinate for the barcode block
774 C<width> The width of the barcode block
775 C<y_scale_factor> The scale factor to be applied to the y axis of the barcode block
776 C<barcode_data> The data to be encoded in the barcode
777 C<barcode_type> The barcode type (See the C<new()> method for supported barcode types)
783 width => $barcode_width,
784 y_scale_factor => $barcode_y_scale_factor,
785 barcode_data => $barcode,
786 barcode_type => $barcodetype,
791 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.
794 C<my $csv_data = $label->csv_data();>
