一、安装pillow模块(PIL)
pip3 install pillow -i https://pypi.tuna.tsinghua.edu.cn/simple/
二、生成图片验证码
from PIL import Image, ImageDraw, ImageFont, ImageFilter
import random
def check_code(width=120, height=30, char_length=5, font_file='utils/Monaco.ttf', font_size=28):
code = []
img = Image.new(mode='RGB', size=(width, height), color=(255, 255, 255))
draw = ImageDraw.Draw(img, mode='RGB')
def rndChar():
"""
生成随机字母
:return:
"""
return chr(random.randint(65, 90))
def rndColor():
"""
生成随机颜色
:return:
"""
return (random.randint(0, 255), random.randint(10, 255), random.randint(64, 255))
font = ImageFont.truetype(font_file, font_size)
for i in range(char_length):
char = rndChar()
code.append(char)
h = random.randint(0, 4)
draw.text([i * width / char_length, h], char, font=font, fill=rndColor())
for i in range(40):
draw.point([random.randint(0, width), random.randint(0, height)], fill=rndColor())
for i in range(40):
draw.point([random.randint(0, width), random.randint(0, height)], fill=rndColor())
x = random.randint(0, width)
y = random.randint(0, height)
draw.arc((x, y, x + 4, y + 4), 0, 90, fill=rndColor())
for i in range(5):
x1 = random.randint(0, width)
y1 = random.randint(0, height)
x2 = random.randint(0, width)
y2 = random.randint(0, height)
draw.line((x1, y1, x2, y2), fill=rndColor())
img = img.filter(ImageFilter.EDGE_ENHANCE_MORE)
return img, ''.join(code)
if __name__ == '__main__':
image_object, code = check_code()
"""
img,code = check_code()
img.show()
"""
"""
with open('code.png', 'wb') as f:
image_object.save(f, format='png')
"""
"""
from io import BytesIO
stream = BytesIO()
image_object.save(stream, 'png')
stream.getvalue()
"""
三、基本操作
from PIL import Image
img = Image.new(mode='RGB', size=(120, 30), color=(255, 255, 255))
img.show()
with open('code.png', 'wb') as f:
img.save(f, format='png')
img = Image.new(mode='RGB', size=(120, 30), color=(255, 255, 255))
draw = ImageDraw.Draw(img, mode='RGB')
img = Image.new(mode='RGB', size=(120, 30), color=(255, 255, 255))
draw = ImageDraw.Draw(img, mode='RGB')
draw.point([100, 100], fill="red")
draw.point([300, 300], fill=(255, 255, 255))
img = Image.new(mode='RGB', size=(120, 30), color=(255, 255, 255))
draw = ImageDraw.Draw(img, mode='RGB')
draw.line((100, 100, 100, 300), fill='red')
draw.line((100, 100, 300, 100), fill=(255, 255, 255))
img = Image.new(mode='RGB', size=(120, 30), color=(255, 255, 255))
draw = ImageDraw.Draw(img, mode='RGB')
draw.arc((100, 100, 300, 300), 0, 90, fill="red")
img = Image.new(mode='RGB', size=(120, 30), color=(255, 255, 255))
draw = ImageDraw.Draw(img, mode='RGB')
draw.text([0, 0], 'python', "red")
img = Image.new(mode='RGB', size=(120, 30), color=(255, 255, 255))
draw = ImageDraw.Draw(img, mode='RGB')
font = ImageFont.truetype("kumo.ttf", 28)
draw.text([0, 0], 'python', "red", font=font)
