Description Barton Chittenden 2018-04-27 21:30:43 UTC
svc/barcode currently generates the barcode using

    $image = GD::Barcode->new( $type, $barcode )->plot()->png();

From perldoc GD::Barcode

  plot()
    $oGd = $oGdBar->plot([Height => $iHeight, NoText => 0 | 1]);

    creates GD object with barcode image for the $sTxt specified at new
    method. $iHeight is height of the image. If NoText is 1, the image has no
    text image of $sTxt.

     ex.
      my $oGdB = GD::Barcode->new('EAN13', '123456789012');
      my $oGD = $oGdB->plot(NoText=>1, Height => 20);
      # $sGD is a GD image with Height=>20 pixels, with no text.

This was just removing warnings that I was using for debugging.

Bug 20676: svc/barcode should allow barcode to be printed without text

Test plan:

1) Point web browser to
   <staff url>/cgi-bin/koha/svc/barcode?barcode=*12345*&notext=1

   This will display a png image of the barcode *12345* with the
   text *12345* printed below the scannable barcode.

2) Apply patch
3) Refresh the browser. The human readable text no longer appears.
