Question

I am having trouble doing some barcode reading. All of my barcodes are encoded in Code 39.

Here is the code I got from the zbar site and endless googling has returned Null.

from sys import argv
import zbar
import Image

if len(argv) < 2: exit(1)

# create a reader
scanner = zbar.ImageScanner()

# configure the reader
scanner.parse_config('enable')

# obtain image data
pil = Image.open(argv[1]).convert('L')
width, height = pil.size
raw = pil.tostring()

# wrap image data
image = zbar.Image(width, height, 'Y800', raw)

# scan the image for barcodes
scanner.scan(image)
# extract results
for symbol in image:
# do something useful with results
print 'decoded', symbol.type, 'symbol', '"%s"' % symbol.data

# clean up
del(image)

Any kind of help would be greatly appreciated.

Answer 1

It appears that my barcodes are just bad. Also to note that if the barcode is on a document with other data it wont pickup either unless I enable my webcam to scan the barcode. Seems like a limitation or just bad barcodes.
