Python 模擬生成動態(tài)產(chǎn)生驗證碼圖片的方法

$ pip install pillow

from PIL import Image

# 打開圖片,注意路徑
img = Image.open('pitbull.jpeg')
# 獲得圖片尺寸
weight, height = img.size
print('原圖片尺寸：{}x{}'.format(weight, height))

# 進行縮放，縮放 50%
img.thumbnail((weight//2, height//2))
print('調整后的圖片尺寸：{}x{}'.format(weight//2, height//2))

# 將縮放后的圖片保存
img.save('thumbnail.jpg', 'jpeg')

from PIL import Image,ImageFilter

# 打開圖片文件，注意路徑

img = Image.open('pitbull.jpeg')

# 應用模糊濾鏡
img2 = img.filter(ImageFilter.BLUR)

img2.save('blur.jpg', 'jpeg')
