It may be that it scans paper/ink with a laser or something that doesn't reflect the same way on a screen. 


What it sounds like these guys are talking about is having cell  
phones take a picture of the barcode or 2D barcode, and then do image  
processing to get the barcode info. That would work fine on a screen.

I tested and yes my scanner is unable to read a barcode on screen.  
By curiosity, anybody has an idea why ? Do you think it's related

to my scanner or to the screen ?

Thanks

In France we have a saying : "Le client a toujours raison !"
I let you translate ;o)


I'm not sure for not scanning on screen, will try with my poor man  
scanner (Zebex 80) and my beautiful 20" Dell Flat Screen :o)

Why on earth would anyone want to display barcodes on the screen,  
since the
only purpose of a barcode is to provide machine readable data by  
scanning? I

don't think a scanner will work scanning a screen.


Or is there a new generation of computer user that can read  
barcodes without

a scanner? ;-)

Kind regards,

Andrew Ballantine.

It may be useful sometime to have a *quick* generation of a barcode.

For instance to make some test with the POS. But yes maybe  
current SVG stuff

in an XSL:FO file  is enough for such an use

A prospective customer also asked for this. He even suggested to  
use a

commercial tool before I explained that we were already using
Barcode4j.

It seemed that he wanted to show barcodes on screen hence the gif/ 
png

question.

So I presume your response is : no ;o)

Thanks David

Why do you want images for the barcodes? Is this for something  
other

than a printed document, so the current SVG stuff in an XSL:FO file
won't work for you?

Hi all,


I want to create a new functionnality to quickly produce GIF or  
PNG

Products BarCodes images usgin Barcode4j.
I want to add a new menu option that may be used after for more
functionnalties from Catalog/Product .


I know that Barcode4j is already used in PDF generation however  
I'm

not aware of any use for gif/png generation on the fly in OFBiz.
Is there alerady such functionnality somewhere hidden ?

Actually this is a 1st step toward a tool (in Webtools certainly)
to generate massive products barcodes for catalog(s) using  such
templates
as in http://www.worldlabel.com/ (hoping to use http://
www.worldlabel.com/Pages/openoffice-template.htm not sure just a
plan for
now)

Thanks

Jacques
