import barcode
from barcode.writer import ImageWriter
code=input("Enter Code")
EAN = barcode.get_barcode_class('ean8')
ean = EAN(code, writer=ImageWriter())
imag = ean.save('barcode')

Sometimes these unequal lines appears in my image. Why is that so? They are not that visible though, but it seems quite odd when they appear multiple times. The same thing happens when I try to print code 128 and code 39.

My output:

Get Same issue.

Code : 00000

itf = ITF(u'00000', writer=ImageWriter())

itf
<ITF('000000')>

itf.build()
['11001100110011001111100000111110000011001100110011111000001111100000110011001100111110000011111000001100111110011']

fullname = itf.save('itf_barcode')

Image:

We can see in the 3 last bar, that the tiny bar have not the good width.

But if i use the SVGWriter instead of the ImageWriter, the bar have the correct width.

But if i use the `SVGWriter` instead of the `ImageWriter`, the bar have the correct width.

You probably want guardbars: EAN(code, writer=ImageWriter(), guardbars=True)

You probably want `guardbars`: `EAN(code, writer=ImageWriter(), guardbars=True)`

@WhyNotHugo Probably yes, but the guardbars option is not available in itf.py
