新年要到了，明天就是2020了，还没人送你头像装饰？让Serverless架构送你吧！
先分享一下地址：(http://serverless.0duzhan.com/app/new_year_add_photo_decorate/)
整体预览：
主要功能就是选择一个图片，上传自己的头像，然后点击生成就可以：
代码也很简单：
import base64, json
from PIL import Image
import uuid
def return_msg(error, msg):
return_data = {
"uuid": str(uuid.uuid1()),
"error": error,
"message": msg
}
print(return_data)
return return_data
def do_circle(base_pic):
icon_pic = Image.open(base_pic).convert("RGBA")
icon_pic = icon_pic.resize((500, 500), Image.ANTIALIAS)
icon_pic_x, icon_pic_y = icon_pic.size
temp_icon_pic = Image.new('RGBA', (icon_pic_x + 600, icon_pic_y + 600), (255, 255, 255))
temp_icon_pic.paste(icon_pic, (300, 300), icon_pic)
ima = temp_icon_pic.resize((200, 200), Image.ANTIALIAS)
size = ima.size
# 因为是要圆形，所以需要正方形的图片
r2 = min(size[0], size[1])
if size[0] != size[1]:
ima = ima.resize((r2, r2), Image.ANTIALIAS)
# 最后生成圆的半径
r3 = 60
imb = Image.new('RGBA', (r3 * 2, r3 * 2), (255, 255, 255, 0))
pima = ima.load() # 像素的访问对象
pimb = imb.load()
r = float(r2 / 2) # 圆心横坐标
for i in range(r2):
for j in range(r2):
lx = abs(i - r) # 到圆心距离的横坐标
ly = abs(j - r) # 到圆心距离的纵坐标
l = (pow(lx, 2) + pow(ly, 2)) ** 0.5 # 三角函数 半径
if l < r3:
pimb[i - (r - r3), j - (r - r3)] = pima[i, j]
return imb
def add_decorate(base_pic):
try:
base_pic = "./base/%s.png" % (str(base_pic))
user_pic = Image.open("/tmp/picture.png").convert("RGBA")
temp_basee_user_pic = Image.new('RGBA', (440, 440), (255, 255, 255))
user_pic = user_pic.resize((400, 400), Image.ANTIALIAS)
temp_basee_user_pic.paste(user_pic, (20, 20))
temp_basee_user_pic.paste(do_circle(base_pic), (295, 295), do_circle(base_pic))
temp_basee_user_pic.save("/tmp/output.png")
return True
except Exception as e:
print(e)
return False
def main_handler(event, context):
try:
print("将接收到的base64图像转为pic")
imgData = base64.b64decode(json.loads(event["body"])["pic"].split("base64,")[1])
with open('/tmp/picture.png', 'wb') as f:
f.write(imgData)
basePic = json.loads(event["body"])["base"]
addResult = add_decorate(basePic)
if addResult:
with open("/tmp/output.png", "rb") as f:
base64Data = str(base64.b64encode(f.read()), encoding='utf-8')
return return_msg(False, {"picture": base64Data})
else:
return return_msg(True, "饰品添加失败")
except Exception as e:
return return_msg(True, "数据处理异常： %s" % str(e))
def test():
with open("test.png", 'rb') as f:
image = f.read()
image_base64 = str(base64.b64encode(image), encoding='utf-8')
event = {

print(main_handler(event, None))
if __name__ == "__main__":
test()
在我的目录下还有几个图片文件：
image
另外这个代码需要依赖pillow，但是我电脑时mac的，pillow又有二进制，所以之前的项目就派上用场了：
http://serverless.0duzhan.com/app/new_year_greeting_card/

下载之后，直接放目录下：
image
然后还需要有一个前端页面，用mui，index页面：
