python自动生成iOS各尺寸规格icon

使用python自动生成iOS各尺寸规格icon(基于一张1024大图),代码如下:

import PIL.Image
imgNames = [((72,72),"icon-72.png"),((40,40),"icon-40.png"),((80,80),"icon-40@2x.png"),((50,50),"icon-50.png"),((100,100),"icon-50@2x.png"),((60,60),"icon-60.png"),((120,120),"icon-60@2x.png"),((180,180),"icon-60@3x.png"),((72,72),"icon-72.png"),((114,114),"icon-72@2x.png"),((152,152),"icon-76@2x.png"),((76,76),"icon-76.png"),((58,58),"icon-small@2x.png"),((29,29),"icon-small.png"),((57,57),"icon.png"),((114,114),"icon@2x.png")]

im = PIL.Image.open("1024.png")
i = 0
for i in range(len(imgNames)):
imt = im
size = imgNames[i][0]
#print size
name = imgNames[i][1]
#print name+type(name)
imt_r = imt.resize(size,PIL.Image.LANCZOS)
imt_r.save(name)
i = i+1

mac内置python环境(可能不包含PIL库,需下载),使用终端相关命令即可生成:

1.cd至1024图所在目录,将以上代码在相同目录下用vi保存为**.py

2.python **.py即可

3.其他尺寸需求,可自由在imgNames中修改
