=head1 SYNOPSIS
|
|
|
|
use C4::Barcodes::PrinterConfig;
|
|
|
|
=head1 DESCRIPTION
|
|
|
|
This package is used to deal with labels in a pdf file. Giving some parameters,
|
|
this package contains several functions to handle every label considering the
|
|
environment of the pdf file.
|
|
|
|
=head1 FUNCTIONS
|
|
|
|
=head2 my @positionsForX;
|
|
|
|
Takes all the X positions of the pdf file.
|
|
|
|
=head2 my @positionsForY;
|
|
|
|
Takes all the Y positions of the pdf file.
|
|
|
|
=head2 my $firstLabel = 1;
|
|
|
|
Test if the label passed as a parameter is the first label to be printed into the pdf file.
|
|
|
|
=head2 setPositionsForX
|
|
|
|
C4::Barcodes::PrinterConfig::setPositionsForX($marginLeft, $labelWidth, $columns, $pageType);
|
|
|
|
Calculate and stores all the X positions across the pdf page.
|
|
|
|
C<$marginLeft> Indicates how much left margin do you want in your page type.
|
|
|
|
C<$labelWidth> Indicates the width of the label that you are going to use.
|
|
|
|
C<$columns> Indicates how many columns do you want in your page type.
|
|
|
|
C<$pageType> Page type to print (eg: a4, legal, etc).
