HEADS UP: Change to BWIPP that impacts frontends

t...@terryburton.co.uk (Terry Burton) — Tue, 05 Jan 2010 15:42:37 UT

Hi all,
After successful testing I have changed barcode.ps so that rather than
provide a set of procedure definitions it instead defines a set of
named resources. There are many advantages to deploying a Postscript
library using this mechanism which are described in this document [1].
Since named resources are a standard feature of LanguageLevel 2

Perl bindings

Hello group,
I am working on a [Perl binding for BWIPP]
[⁰]. As of 2009-12-10 the 2D barcodes are
implemented and I have already had a couple
of releases to shake out the teething
problems. Here's a taste of the API,
straight from [a module's synopsis] [¹]:
use PostScript::Barcode::qrcode qw();

You can accomplish this using the barcodewidth function I contributed a while back.

See here.

RE: [postscriptbarcode] Right aligning barcodes

j...@optifacts.com (John H) — Tue, 17 Nov 2009 17:32:15 UT

The way I've been achieving this lately is by rotating the barcode 180
degrees and setting x,y coords as needed... Basically printing it
'upside-down'. Barcode scanners don't seem to complain and our customer
base is happy.

Right aligning barcodes

googlegro...@redgrittybrick.org (RedGrittyBrick) — Tue, 17 Nov 2009 14:38:10 UT

I'm using Code-128 and wish to right align the barcode against the
right margin of the printable area.

When printing text using Postscript I can use the stringwidth function
to achieve this.

Is there any recommended or suggested way to achieve right alignment
with barcodewriter? The length of my barcode data is not fixed so I

Hi,
Thanks to some excellent work by Chapman Flack, in the form of
net.anastigmatix.Packager [1], the named resource delivery format for
BWIPP [2] is now more compact and contains DSC compliant comments,
which means that it should be more digestible for document management
software.
I've refreshed this example [3].

Issue with text positioning: textxalign, textyoffset

giul...@gmail.com (Giulio) — Wed, 11 Nov 2009 15:34:09 UT

I'm using barcode.ps from a tarball which carries 2009-11-06 as the
most recent date in CHANGES.

1) textxalign=center
I'm trying using textxalign=center but the output I get is weird, it
doesn't seem to be really centered, sometimes using textxalign=center
gets things worse than the default from a centering perspective.

Hi Nick,
I've purposefully not made it trivial for others to replicate the
online generator functionality since its high popularity provides a
(small) source of funding for the BWIPP project.
I will however provide the source to individuals who want to use it
for "internal-only" use. Let me know if this is the case.

Web front end example source code

nick...@gmail.com (Nick A) — Sat, 07 Nov 2009 00:25:48 UT

(I couldn't find anything in the archives or docs, so I thought I'd
ask.)

Is there any available source code (PHP, Perl, etc.) for a web front-
end to the PostScript Barcode Writer?

The PostScript Barcode Writer is probably the most impressive barcode
generating library I've seen (open source or commercial), but I've

Hi,
A non-zero number system is indeed undefined for UPC-E.
From a technical standpoint I think that your solution is fine,
however I have found in the past that designing the input in just such
a way results in confusion for the (non-technical) users of the
project.
I will however add a defensive check to ensure that the encoder fails

Are non-zero number systems allowed in UPC-E?

koalaatb81dot...@gmail.com (Koala) — Thu, 05 Nov 2009 08:36:28 UT

Dear Terry,

After searching via Google, I found that:

1. "A UPC-E barcode has 6 digits with an implied number system 0."
[[link]]

2. "UPC-E is a variation of the UPC-A symbol that is used for number
system 0."

ASCII85 encoding of named resources and a new LTO tape label example

t...@terryburton.co.uk (Terry Burton) — Tue, 13 Oct 2009 14:59:16 UT

Hi,
I've recently changed the packaging format for the PostScript named
resource delivery method [1] for BWIPP so that the resource files are
now ASCII85 encoded. This makes them a lot more suitable for copying
and pasting into PS documents.
They now look something like this:

Hi,
Just a quite note to say that I have recently updated the symbologies
documentation in the project wiki so that it is now up to date with
the options for 2D barcodes:

All the best,
