Create only barcode without Text using Code39?

[Rapid1898-code]

Hello - create a barcode using the following code:

from barcode import Code39
from barcode.writer import ImageWriter
with open("somefile.png", "wb") as f:
  Code39(str(5234), writer=ImageWriter()).write(f)

Generally this works fine - but is there any way so only the barcode without the text under it is outputted?

    options = {
        "write_text": False,
    }
    bio = BytesIO()
    Code39(str(5234), writer=ImageWriter()).write(bio, options=options)

You can modify the options for the write (render), or you can just create a subclass of Code39 and customize it however you want.

Hope it helps, Max

Thanks - i tried your code snippet and it creates a somefile.png - but i can´t open the file - it has 0 bytes

from barcode import Code39
from barcode.writer import ImageWriter
from io import BytesIO
options = {
    "write_text": False,
}
bio = BytesIO()
with open("somefile.png", "wb") as f:
  Code39(str(5234), writer=ImageWriter()).write(bio, options=options)

I am not completely sure, to be honest.
But for the ImageWriter, as it needs Pillow python dependency, I think that could happen.

I had Pillow installed, what if you switch from the ImageWriter to the SVGWriter which is the default writer?

I tested the chunk of code I shared with you, and it worked fine.

Still, although I don't think that's the reason, you can copy the default options from here and tweak it property by property, incrementally, it should work fine out of the box with the default options, if not, then there's some config issue with your python-barcode package, or the environment where you're trying to render using Python, would be my guess.

Hope it helps, Max

I ran your code - but when i want to open the created somefile.png i just get an error (and the file has 0kb) -
