From 7b86c0ad698a48584d48c561b62efeb35cdfca2c Mon Sep 17 00:00:00 2001 From: Kyle M Hall Date: Thu, 4 Dec 2014 07:48:35 -0500 Subject: [PATCH] Bug 13545 - Add barcode image generator service If we add a script to Koha that can be passed a barcode, we will be able to easily embed item and patron barcodes into html printable slips and notices. This can be very helpful for librarians, as it means scanning an image instead of typing in the barcode manually. This patch adds a barcode image generator that can be passed a barcode and an optional type ( defaults to Code39, all GD::Barcode types should work ). This image can be embedded in html slips and notices. ( e.g. ) Test Plan: 1) Apply this patch 2) Browse to /cgi-bin/koha/svc/barcode?barcode=123456789 on your server 3) Note the barcode image Signed-off-by: Brandon --- svc/barcode | 41 +++++++++++++++++++++++++++++++++++++++++ 1 file changed, 41 insertions(+) create mode 100755 svc/barcode diff --git a/svc/barcode b/svc/barcode new file mode 100755 index 0000000..8c4e745 --- /dev/null +++ b/svc/barcode @@ -0,0 +1,41 @@ +#!/usr/bin/perl + +# Copyright 2014 ByWater Solutions +# +# This file is part of Koha. +# +# Koha is free software; you can redistribute it and/or modify it under the +# terms of the GNU General Public License as published by the Free Software +# Foundation; either version 3 of the License, or (at your option) any later +# version. +# +# Koha is distributed in the hope that it will be useful, but WITHOUT ANY +# WARRANTY; without even the implied warranty of MERCHANTABILITY or FITNESS FOR +# A PARTICULAR PURPOSE.
