Hi all,
Can anyone recommend a solution for creating barcodes on a webserver. We're
looking for a solution that will work on a Windows webserver, but we could
always call a webservice on a Linux box.
Ideally the solution should be able to create the barcode as an image in
different resolutions and formats i.e. bitmap, jpeg and vector/SVG
Perhaps POV-Ray could be used???!!!
Thanks in advance
Reuben

You do *not* want to use JPEG for a barcode.

What needs to be able to read the barcode?
If it only needs to be readable by some software that you're going to
write yourself, then what you have is a simple pattern matching problem.
If, on the other hand, it's supposed to be readable by an existing
system, you need to look up what standard(s) it conforms to, and take it
from there...

What kind of barcodes? 1D? 2D? What standards?
The easiest is probably to google for "generate barcodes" and pick one. It
was a well-solved problem when I last looked at it several years ago.

A barcode in jpeg format? Jpeg would be approximately the worst possible
format you could *ever* choose for a 2-color image which has thin vertical
bars of random width.
(Besides, there would be no size advantage whatsoever. On the contrary.
A jpeg of sufficient quality will most probably be at least a hundred times
larger than an optimized png. At least.)

Actually, it doesn't work at all if you make the image the same size as the
barcode. I.e., if the barcode is a 140 pixels wide, and you make a jpeg
image 140 pixels wide (say, for display on a device with 140 pixels across),
you won't have a usable barcode. You'd have to make the jpeg several
multiples larger.
