563 C4::Labels::Label - A class for creating and manipulating label objects in Koha
567 This module provides methods for creating, and otherwise manipulating single label objects used by Koha to create and export labels.
573 Invoking the I<new> method constructs a new label object containing the supplied values. Depending on the final output format of the label data
574 the minimal required parameters change. (See the implimentation of this object type in labels/label-create-pdf.pl and labels/label-create-csv.pl
575 and labels/label-create-xml.pl for examples.) The following parameters are optionally accepted as key => value pairs:
577 C<batch_id> Batch id with which this label is associated
578 C<item_number> Item number of item to be the data source for this label
579 C<height> Height of this label (All measures passed to this method B<must> be supplied in postscript points)
580 C<width> Width of this label
581 C<top_text_margin> Top margin of this label
582 C<left_text_margin> Left margin of this label
583 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:
591 CODE39MOD = Code 3 of 9 with modulo 43 checksum
594 CODE39MOD10 = Code 3 of 9 with modulo 10 checksum
597 COOP2OF5 = A varient of 2 of 5 barcode based on NEC's "Process 8000" code
600 INDUSTRIAL2OF5 = The standard 2 of 5 barcode (a binary level bar code developed by Identicon Corp. and Computer Identics Corp. in 1970)
604 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:
609 BIB = Only the bibliographic data is printed
612 BARBIB = Barcode proceeds bibliographic data
615 BIBBAR = Bibliographic data proceeds barcode
618 ALT = Barcode and bibliographic data are printed on alternating labels
621 BAR = Only the barcode is printed
625 C<guidebox> Setting this to '1' will result in a guide box being drawn around the labels marking the edge of each label
626 C<font> Defines the type of font to be used on labels. NOTE: The following fonts are available by default on most systems:
640 TBI = Times Bold Italic
649 CO = Courier Oblique (Italic)
652 CBO = Courier Bold Oblique
661 HBO = Helvetical Bold Oblique
665 C<font_size> Defines the size of the font in postscript points to be used on labels
666 C<callnum_split> Setting this to '1' will enable call number splitting on labels
667 C<text_justify> Defines the text justification to be used on labels. NOTE: The following justification styles are currently supported by label creator code:
682 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
683 to your MARC frameworks. Specify MARC subfields as a 4-character tag-subfield string: ie. 254a Enclose a whitespace-separated list of fields
684 to concatenate on one line in double quotes. ie. "099a 099b" or "itemcallnumber barcode" Static text strings may be entered in single-quotes:
685 ie. 'Some static text here.'
686 C<text_wrap_cols> Defines the column after which the text will wrap to the next line.
688 =head2 get_label_type()
690 Invoking the I<get_label_type> method will return the printing type of the label object.
693 C<my $label_type = $label->get_label_type();>
695 =head2 get_attr($attribute)
697 Invoking the I<get_attr> method will return the value of the requested attribute or -1 on errors.
700 C<my $value = $label->get_attr($attribute);>
702 =head2 create_label()
704 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
705 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
706 code is responsible to properly format the text for insertion into the pdf stream as well as the actual insertion.
709 my $label_text = $label->create_label();
711 =head2 draw_label_text()
713 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
714 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)
716 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)
717 C<lly> The lower-left y coordinate for the text block
718 C<top_text_margin> The top margin for the text block.
719 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)
720 C<font> The font to use for this label. See documentation on the new() method for supported fonts.
721 C<font_size> The font size in points to use for this label.
722 C<justify> The style of justification to use for this label. See documentation on the new() method for supported justification styles.
725 C<my $label_text = $label->draw_label_text(
728 top_text_margin => $label_top_text_margin,
729 line_spacer => $text_leading,
731 font_size => $text_font_size,
732 justify => $text_justification,
737 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
738 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
739 type of the current template being used.):
741 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)
742 C<lly> The lower-left y coordinate for the barcode block
743 C<width> The width of the barcode block
744 C<y_scale_factor> The scale factor to be applied to the y axis of the barcode block
745 C<barcode_data> The data to be encoded in the barcode
746 C<barcode_type> The barcode type (See the C<new()> method for supported barcode types)
752 width => $barcode_width,
753 y_scale_factor => $barcode_y_scale_factor,
754 barcode_data => $barcode,
755 barcode_type => $barcodetype,
760 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.
763 C<my $csv_data = $label->csv_data();>
