Here's my code:

def barcode_to_html(order_id, box_num):
 from barcode import Code128
 from barcode.writer import ImageWriter
 from io import BytesIO
 import base64
 file_like_object = BytesIO()
 writer = ImageWriter()
 writer.set_options({ 'module_height': 10.0 }) ## NOT WORKING
 value = f'{order_id}-{box_num}'
 Code128(value, writer=writer).write(file_like_object)
 encoded = base64.b64encode(file_like_object.getvalue()).decode("ascii")
 return f'<img src="data:image/png;base64,{encoded}" />'

Here's my code: ``` def barcode_to_html(order_id, box_num): from barcode import Code128 from barcode.writer import ImageWriter from io import BytesIO import base64 file_like_object = BytesIO() writer = ImageWriter() writer.set_options({ 'module_height': 10.0 }) ## NOT WORKING value = f'{order_id}-{box_num}' Code128(value, writer=writer).write(file_like_object) encoded = base64.b64encode(file_like_object.getvalue()).decode("ascii") return f'<img src="data:image/png;base64,{encoded}" />' ```

I had this issue aswell, its not totally clear in the documentation but you can pass the options to .write() instead:

Code128(value, writer=writer).write(file_like_object, options={'<option>': <value>})

Use the options this way ,

 from barcode import ITF
 from io import BytesIO
 stream = BytesIO()
 options = {
 "module_width": 0.1,
 "module_height": 2,
 "quiet_zone": 0.1,
 "write_text": False,
 "text_distance": 2,
 }
 Code128(code_str, writer=writer1, narrow=1, wide=3).write(stream, options)
