图像处理Pillow库
本帖最后由 gzj137070928 于 2020-12-1 11:52 编辑# 缩略图：thumbnail函数:thumbnail(size, Image.ANTIALIAS)
# 参数size为一个元祖，指定生成缩略图的大小
# 对原图修改后需要保存，处理后的图片不会被拉伸
# 实例：PIL生成验证码

image = Image.new('RGB', (width, height),(255,255,255))
font = ImageFont.truetype('arial.ttf', 36)
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())
# 模糊处理：
image = image.filter(ImageFilter.BLUR)
image.save('code.jpg', 'jpeg')
怎么用啊 YoloM 发表于 2020-12-1 21:02
