571 C4::Labels::Label - A class for creating and manipulating label objects in Koha
575 This module provides methods for creating, and otherwise manipulating single label objects used by Koha to create and export labels.
581 Invoking the I<new> method constructs a new label object containing the supplied values. Depending on the final output format of the label data
582 the minimal required parameters change. (See the implimentation of this object type in labels/label-create-pdf.pl and labels/label-create-csv.pl
583 and labels/label-create-xml.pl for examples.) The following parameters are optionally accepted as key => value pairs:
585 C<batch_id> Batch id with which this label is associated
586 C<item_number> Item number of item to be the data source for this label
587 C<height> Height of this label (All measures passed to this method B<must> be supplied in postscript points)
588 C<width> Width of this label
589 C<top_text_margin> Top margin of this label
590 C<left_text_margin> Left margin of this label
591 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:
599 CODE39MOD = Code 3 of 9 with modulo 43 checksum
602 CODE39MOD10 = Code 3 of 9 with modulo 10 checksum
605 COOP2OF5 = A varient of 2 of 5 barcode based on NEC's "Process 8000" code
608 INDUSTRIAL2OF5 = The standard 2 of 5 barcode (a binary level bar code developed by Identicon Corp. and Computer Identics Corp. in 1970)
612 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:
617 BIB = Only the bibliographic data is printed
620 BARBIB = Barcode proceeds bibliographic data
623 BIBBAR = Bibliographic data proceeds barcode
626 ALT = Barcode and bibliographic data are printed on alternating labels
629 BAR = Only the barcode is printed
633 C<guidebox> Setting this to '1' will result in a guide box being drawn around the labels marking the edge of each label
634 C<font> Defines the type of font to be used on labels. NOTE: The following fonts are available by default on most systems:
648 TBI = Times Bold Italic
657 CO = Courier Oblique (Italic)
660 CBO = Courier Bold Oblique
669 HBO = Helvetical Bold Oblique
673 C<font_size> Defines the size of the font in postscript points to be used on labels
674 C<callnum_split> Setting this to '1' will enable call number splitting on labels
675 C<text_justify> Defines the text justification to be used on labels. NOTE: The following justification styles are currently supported by label creator code:
690 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
691 to your MARC frameworks. Specify MARC subfields as a 4-character tag-subfield string: ie. 254a Enclose a whitespace-separated list of fields
692 to concatenate on one line in double quotes. ie. "099a 099b" or "itemcallnumber barcode" Static text strings may be entered in single-quotes:
693 ie. 'Some static text here.'
694 C<text_wrap_cols> Defines the column after which the text will wrap to the next line.
696 =head2 get_label_type()
698 Invoking the I<get_label_type> method will return the printing type of the label object.
701 C<my $label_type = $label->get_label_type();>
703 =head2 get_attr($attribute)
705 Invoking the I<get_attr> method will return the value of the requested attribute or -1 on errors.
708 C<my $value = $label->get_attr($attribute);>
710 =head2 create_label()
712 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
713 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
714 code is responsible to properly format the text for insertion into the pdf stream as well as the actual insertion.
717 my $label_text = $label->create_label();
719 =head2 draw_label_text()
721 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
722 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)
724 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)
725 C<lly> The lower-left y coordinate for the text block
726 C<top_text_margin> The top margin for the text block.
727 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)
728 C<font> The font to use for this label. See documentation on the new() method for supported fonts.
729 C<font_size> The font size in points to use for this label.
730 C<justify> The style of justification to use for this label. See documentation on the new() method for supported justification styles.
733 C<my $label_text = $label->draw_label_text(
736 top_text_margin => $label_top_text_margin,
737 line_spacer => $text_leading,
739 font_size => $text_font_size,
740 justify => $text_justification,
745 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
746 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
747 type of the current template being used.):
749 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)
750 C<lly> The lower-left y coordinate for the barcode block
751 C<width> The width of the barcode block
752 C<y_scale_factor> The scale factor to be applied to the y axis of the barcode block
753 C<barcode_data> The data to be encoded in the barcode
754 C<barcode_type> The barcode type (See the C<new()> method for supported barcode types)
760 width => $barcode_width,
761 y_scale_factor => $barcode_y_scale_factor,
762 barcode_data => $barcode,
763 barcode_type => $barcodetype,
768 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.
771 C<my $csv_data = $label->csv_data();>
