This patch adds a new page providing an interface for generating
barcodes using svc/barcode. A form allows the user to choose various
parameters and see the resulting barcode image.
To test, apply the patch and rebuild the staff interface SCSS
(https://wiki.koha-community.org/wiki/Working_with_SCSS_in_the_OPAC_and_staff_client).
- Go to the "Tools" home page. Follow the link to "Barcode image
generator."
- On the barcode image generator page, confirm that there is a "Barcode
image generator" link in the sidebar and that it is displayed with
bold text.
- Test the features of the form:
- Enter a numeric value in the "Barcode" field and tab out of the
field or click "Show barcode" button. A barcode of type "Code39"
should be shown with the text of the barcode included in the
image below the barcode.
- A text area below the barcode image should show the HTML used to
generate the preview image.
- Clicking in this textarea should automatically add the contents to
the clipboard. You should be shown a message, "HTML copied to the
clipboard."
- Check the "hide text" checkbox. The barcode should be redisplayed
without the text.
- Check that changing the "barcode height" value is reflected
correctly in the barcode image.
- Try adding non-numeric data in the "Barcode" field. You should be
shown an error message, "Barcodes of type [type] must be numeric."
- Test these other numeric barcode types: Code39, COOP2of5, EAN13,
EAN8, IATA2of5, Industrial2of5, ITF, Matrix2of5, NW7, UPCA, and
UPCE.
Note that EAN13, EAN8, UPCA, and UPCE expect specific patterns. Test
values (found here: https://barcode.tec-it.com/en/UPCE):
EAN13: 978020137962
EAN8: 9031101
UPCA: 72527273070
UPCE: 0123456
- Change the barcode type to "QRcode."
- The form should change, hiding the "Hide text" checkbox and
showing a new ranger slider for "QR Code module size."
- The barcode field should now be labeled "Text, URL, or barcode,
etc"
- The barcode field hint should change to a hint about QRcode
dimensions.
- Changing the "module size" slider should change the size of the
generated QR code. As you change the slider the selected value
should be reflected in the box.
