- pip install easy-captcha
- python setup.py install
from captcha.generator import DefaultGenerator
generator = DefaultGenerator()
captcha = generator.make_captcha(string='ABCD')
captcha.save('test-default.png')the make_captcha method return a PIL Image object, you can save it with your any type you wanted, easy to use.

class MyCaptchaGenerator(DefaultGenerator):
def _get_font(self, size):
p = Path('./fonts/test.otf')
font = self._load_font(path=p, size=size)
return fontif you just want to use your font instead of the default font, just reimplement the _get_font method, make the method return your font.
if you want to custom the captcha generator, you just need to subclass the captcha.generator.BaseGenerator class. when you subclass the BaseGenerator then you could use the method inside the BaseGenerator to make your own style captcha genrator.
if the default drawing methods are not well enough for you, you could just use the pillow staff to make your own generator. this whole package is based on pillow, so just feel free to modify it.
for more details just check the code below. the important thing is that when you subclass the BaseGenerator, you just need to implement the make_captcha method and _get_font method.
class DefaultGenerator(BaseGenerator):
FONT = 'TruenoBdOlIt.otf'
def make_captcha(self,
string: str = None,
font_size: int = 48,
image_size: tuple = None):
captcha = self._make_captcha(string, font_size)
size = image_size if image_size else self.size
captcha = self._resize(captcha, size)
return captcha
def _make_captcha(self, string, font_size):
font = self._get_font(font_size)
char_images = self._make_char_images(string,
font,
rotate=None,
color=self._rand_color)
image = self._composite_char_images(char_images,
color=self._get_color(255,
255,
255))
self._rand_noise_lines(image, number=3)
return image
def _get_font(self, size: int):
font = self._load_font(name=self.FONT, size=size)
