Re: Name for barcode-reading module?

The rest I would have to open to read what they do exactly. Barcode::OCR is sself explanatory, IMHO. But doing OCR of barcodes is ambiguous. Optical character recognition often captures style info as well as character sequences, at least the one that came with my scanner a few years ago does, and very well too -- scanning magazine articles into pdfs resulted in images that looked just like the pages, except that the text in the middle of the page was clipboardable while towards the spine, where things got skewed, there was a big vertical image -- I was, and remain, impressed. Based on that as an experience with OCR, I might expect Barcode::OCR to somehow allow barcodes to pass through an OCR process intact, perhaps by adjsuting image compression parameters within their boundaries. I think Barcode::Decoder depicts by the name exactly what it does. It decodes barcodes. Perfect. The rest I would have to open to read what they do exactly. Barcode::Decoder is sself explanatory, IMHO. -- Freedom's colors are red, white and black and blue.

Of those, Recognizer is better IMO, because you're actually aiming to *understand* the barcode and turn it into a number, just like OCR turns an image into a bunch of characters, and not merely find the part of the image that contains the barcode. -- David Cantrell | Godless Liberal Elitist Vegetarian: n: a person who, due to malnutrition caused by poor lifestyle choices, is eight times more likely to catch TB than a normal person
Re: Name for barcode-reading module?
Okay, it seems like Barcode is the best namespace for it. As Bill says, the module is essentially OCR for barcodes, so if there were a good space for OCR-related modules it might fit there, but there doesn't seem to be one. I've thought about Barcode::Reader, but that could give people the idea that it's for use with barcode readers, when the whole point is that it allows you to use images of barcodes created by a camera or scanner *without* having a barcode reader. Right now, I'm leaning toward Barcode::Finder, or maybe Barcode::Recognizer. Anyone have any better ideas? -- Keith C. Ivey ke...@iveys.org Washington, DC

There's an article in the latest Linux Journal about a library and command-line tool for parsing 2D barcodes (I use quotes because it's pixels, not bars). I don't remember offhand what it's called, but as I was reading the article I was thinking of you and how someone ought to write a Perl interface to it if there isn't one already

Re: Name for barcode-reading module?
As the author of Barcode::Code128 (though I haven't done anything with barcodes in many years) I don't see anything wrong with the Barcode namespace. I think it predates the others, but I'm too lazy to dig up the dates on each. Anyway, I think filing it under Business is silly, since there are plenty of non-business uses of barcodes, and unless your barcode is nothing but an extension of GD I wouldn't put it there. If I understand, your code is something like OCR for barcodes?

Re: Name for barcode-reading module?
Hi Keith: I have to say, I am pleased that people are working on enriching CPAN's offerings. Currently it does lack Barcode handling support, from what I can tell. I would be totally behind a project that would bring everything under a consistent Barcode:: interface - that is, the processing/input, creation, checking, etc. of barcodes. So, while new namespaces are generally a bad idea, I think that Barcode processing support can't realistically exist under anything else. So, go ahead and register the Barcode namespace from PAUSE, and commit away. As a side project, I think it would be beneficial to contact the authors of the other Barcode-related modules and see if you can bring them under the Barcode:: namespace. Please do feel free to contact me if you have more specific questions, and thanks for consulting module-authors :-) Unfortunately I don't personally have a whole lot of experience working with barcodes, but I definitely think this sort of thing is something others will find extremely useful!
