NAME

       Barcode::DataMatrix::PNG - Generate PNG graphical representations of Data Matrix barcodes

SYNOPSIS

           use Barcode::DataMatrix::PNG;
           my $data = Barcode::DataMatrix::PNG->new->(barcode=>'test_barcode');
                                                                                               # Minimal call for a new object.
               $data->encode();                                                # Encode the Barcode data.
               $data->render();                                                # Default:  Render the image to <STDOUT>
               $data->target = 'pass';                                 # C<return()> the image.
               my $barcode = $data->render();                  # Return a PNG representation of a DataMatrix Barcode.
               my $my_barcode = $data->echo_barcode(); # Return a human-readable string of the encoded data.

               $data->barcode = "A new barcode.";              # To render a new barcode with the same object.
               $data->target = 'stdout';
               $data->encode();
               $data->render();                                                # etc.

DESCRIPTION

       This class is used to create graphical representations of data matrix barcodes.  It is an
       extension of the Barcode::DataMatrix class.  Potential applications include graphically
       oriented documents such as PDF, printable web documents, invoices, packing lists, shipping
       labels, etc....

METHODS

   new (%attributes)
       Minimal initiation of a barcode object is new(barcode=>"yourtext").  Options may be added
       via the %attributes in any order.

       Default settings of output to "STDOUT" with a resolution of 3 pixels will be used unless
       changed.

   encode ()
       Encode the barcode string into DataMatrix format.  An "encode()" must be completed prior
       to rendering a barcode.

   render ()
       Render a PNG image of the created barcode.  The graphic will be rendered based on settings
       selected.

       An exception may be thrown by foundation classes if they are unable to generate the
       barcode data or graphics.

   echo_barcode()
       Echo a human-readable representation of the barcode data stored in $this->{"barcode"}

ATTRIBUTES

   barcode
       Ascii string data to be inserted into the barcode.

   resolution
       The resolution (in pixels) of the barcode to be generated.   The default setting is 3
       pixels resolution.

   target
       Default output is "stdout".  Options are "stdout" or "pass".  Pass will "return()" the
       barcode PNG data for use.
