Python3第三方模块之Pillow模块的使用详解

pip install pillow

from PIL import Image
#打开一个jpg文件，注意是当前路径：
im = Image.open('test.jpg')
#获得图像尺寸：
w,h = im.size
print('Original image size: %sx$s'%(w,h))
#缩放到50%：
im.thumnail((w//2,h//2))
print('Resize image to: %sx%s'%(w//2,h//2))
#把缩放后的图像用jpeg格式保存
im.sava('thumbnall.lph')

from PIL import Image, ImageFilter
#打开一个jpg图像文件，注意是当前路径：
im= Image.open('test.jpg')
#应用模糊滤镜：
im2 =im.filter(ImageFilter.BLUR)
im2.save('blur.jpg','jpeg')

from PIL import Image, ImageDraw, ImageFont, ImageFilter
import random
#随机字母
def rndChar():
    return chr(random.randint(65,90))
#随机颜色:
def rndColor():
    return (random.randint(64, 255), random.randint(32,127))
# 240 x 60:
width = 60 * 4
height = 60
image = Image.new('RGB', (width, height), (255, 255, 255))
# 创建Font对象:
font = ImageFont.truetype('Arial.ttf', 36)
# 创建Draw对象:
draw = ImageDraw.Draw(image)
# 填充每个像素:
for x in range(width):
    for y in range(height):
        draw.point((x, y), fill=rndColor())
# 输出文字:
for t in range(4):
    draw.text((60 * t + 10, 10), rndChar(), font=font, fill=rndColor2())
# 模糊:
image = image.filter(ImageFilter.BLUR)
image.save('code.jpg', 'jpeg')
