Is there an option to generate the barcode without the plain text?

You can subclass writers and override the text render method. It probably makes sense to add a flag for this though, since it's a rather common request.

class ImageWitoutTextWriter(ImageWriter):
 def _paint_text(self, xpos, ypos):
 pass

I'm added in class ImageWriter variable print_text. Default value is True, if need create barcode without text, writer=ImageWriter(False)

`class ImageWriter(BaseWriter):

 def __init__(self, print_text=True):
 BaseWriter.__init__(self, self._init, self._paint_module,
 self._paint_text, self._finish)
 self.format = 'PNG'
 self.dpi = 300
 self._image = None
 self._draw = None
 self.print_text = print_text 
 def _init(self, code):
 size = self.calculate_size(len(code[0]), len(code), self.dpi)
 if not self.print_text:
 size = (size[0], int(size[1] * 0.7))
 self._image = Image.new('RGB', size, self.background)
 self._draw = ImageDraw.Draw(self._image)
 def _paint_module(self, xpos, ypos, width, color):
 size = [(mm2px(xpos, self.dpi), mm2px(ypos, self.dpi)),
 (mm2px(xpos + width, self.dpi),
 mm2px(ypos + self.module_height, self.dpi))]
 self._draw.rectangle(size, outline=color, fill=color)
 def _paint_text(self, xpos, ypos):
 if self.print_text:
 font = ImageFont.truetype(FONT, self.font_size * 2)
 width, height = font.getsize(self.text)
 pos = (mm2px(xpos, self.dpi) - width // 2,
 mm2px(ypos, self.dpi) - height // 4)
 self._draw.text(pos, self.text, font=font, fill=self.foreground)`

Would you like to make that into a PR?

For anyone reading this today, _paint_text has been renamed to _create_text.

Was this ever integrated into main? I don't see it in https://github.com/WhyNotHugo/python-barcode/blob/main/barcode/writer.py
