34 C4::Barcodes::PrinterConfig - Koha module dealing with labels in a PDF.
38 use C4::Barcodes::PrinterConfig;
42 This package is used to deal with labels in a pdf file. Giving some parameters,
43 this package contains several functions to handle every label considering the
44 environment of the pdf file.
52 my @positionsForX; # Takes all the X positions of the pdf file.
53 my @positionsForY; # Takes all the Y positions of the pdf file.
54 my $firstLabel = 1; # Test if the label passed as a parameter is the first label to be printed into the pdf file.
56 =item setPositionsForX

60 Calculate and stores all the X positions across the pdf page.
62 C<$marginLeft> Indicates how much left margin do you want in your page type.
64 C<$labelWidth> Indicates the width of the label that you are going to use.
66 C<$columns> Indicates how many columns do you want in your page type.
68 C<$pageType> Page type to print (eg: a4, legal, etc).
