I have come to ask a little question, I installed some python modules to generate barcodes(python-barcode, pybarcode, treepoem, PyUPC-EAN etc.), however this image is generated:
image1:
I want is to know if there is some way or other module that generates the codes in this way:
image2:
this is the code is the one I used for image 1:
import barcode
from barcode.writer import ImageWriter
def genUPCA(code,coding,name):
cod = barcode.get(code, coding, writer=ImageWriter())
filename = cod.save(name)
genUPCA('upca', '123456789102', 'image')
EDIT
from __future__ import absolute_import, division, print_function, unicode_literals;
import upcean
barcode = upcean.oopfuncs.barcode('upce', '01234567')
print(barcode.validate_checksum())
barcode.validate_create_barcode("./IMAGE.png", 4)
output: False
eror:
