python自动化生成IOS的图标

本文实例为大家分享了python自动化生成IOS的图标，供大家参考，具体内容如下

每次上架之前都要生成十几个图片感觉无聊麻烦，考虑使用脚本处理

脚本使用python 和一部分shell 处理的，python部分主要是使用PIL库处理图片，和调用shell脚本，shell 主要是操作文件

#coding=utf-8
import os ,threading
from PIL import Image
import subprocess
import json
class ImgManager(object):
 thread_lock = threading.Lock()
 @classmethod
 def sharedinstance(cls):
   with ImgManager.thread_lock:
     if not hasattr(ImgManager,"instance"):
       ImgManager.instance = ImgManager()
   return ImgManager.instance

# 运行shell命令
 def runshellCMD(self,cmd,dsr):
   progress = subprocess.Popen(cmd,shell=True)
   progress.wait()
   result = progress.returncode
   if result !=0:
     print("％s失败"％(dsr))
   else:
     print("％s成功"％(dsr))

#创建图片
 def createImg(self,model):
   path = '％s/AppStore.png'％(os.getcwd())
   currentPath = "％s/Images/％s"％(os.getcwd(),model.filename)
   print(currentPath)
   im = Image.open(path,'r')
   # w,h=im.size
   # print("％s,％s"％(str(w),str(h)))
   #
   im.thumbnail((float(model.get_wh()),float(model.get_wh())))
   if model.filename.endswith('.png'):
     im.save("％s" ％ (currentPath),"png")
   else:
     # self.runshellCMD("sudo cp ％s ％s" ％ (path, currentPath), "拷贝")
     self.addTransparency(im)
     im.save("％s" ％ (currentPath), "jpeg")
     # r, g, b, alpha = im.split()
     # print("％s"％(str(im.split()[0])))

#修改透明度
 def addTransparency(img, factor=0.0):
   img = img.convert('RGBA')
   img_blender = Image.new('RGBA', img.size, (0, 0, 256, 256))
   img = Image.blend(img_blender, img, factor)
   return img

#解析Contents.json，这个文件每一个Images.xcassets 的AppIcon文件夹都有，直接复用就可以了
 def handle_icon_images(self):

jsonpath = os.getcwd() +"/Contents.json"
   if not os.path.exists(jsonpath):
     print("Contents.json path not exite")
     return
   with open(jsonpath,'r') as f:
     jsonstr = f.read()
   modle = json.loads(jsonstr)
   arrs = modle['images']
   # print(arrs)
   icon_models=[]
   for obj in arrs:
     size=obj["size"]
     idiom=obj["idiom"]
     filename=obj["filename"]
     scale=obj["scale"]
     icom =iconImg(size=size,idiom=idiom,filename=filename,scale=scale)
     # icon_models.append(icom)
     self.createImg(icom)

"""

"size" : "29x29",
  "idiom" : "iphone",
  "filename" : "Icon-Small@3x.png",
  "scale" : "3x"
 """
 #json 数据里面有效数据的类
class iconImg(object):
 def __init__(self,size,idiom,filename,scale):
   self.size = size
   self.idiom = idiom
   self.filename = filename
   self.scale = scale

def show(self):
   print("％s,％s,％s,％s"％(self.size,self.idiom,self.filename,self.scale))

def get_wh(self):
   return (float(self.size.split('x')[0]))*(float(self.scale.split('x')[0]))

if __name__ == '__main__':
 ImgManager.sharedinstance().handle_icon_images()
