python 根据大图片生成各种规格图片 生成ios需要的各个规格的icon
PIL库要安装,直接使用pip安装:
pip install pillow
可能会报错,我python是3.x版本的,好像2.x版本的没有pip(需要单独安装)
3.x版本的安装如果报一堆错出来,它会提示需先更新pip版本(命令也提示出来了,照着输入执行即可):
`pip install --upgrade pip`
然后再安装插件: `pip install pillow`
python脚本代码:
#!/usr/bin/python # -*- coding:utf-8 -*- # 生成ios需要的各个规格的icon(通过1024*1024的图片) from PIL import Image infile = './expand_iOSicon_by1024/2.png' # input('Please enter the image path: ') outPath = './expand_iOSicon_by1024/2' # input('Please enter the export path: ') print('infile:' + infile) img = Image.open(infile) (w, h) = img.size print('originW:' + str(w) + ',originH:' + str(h)) arr = [40, 60, 58, 87, 80, 120, 180] for index in arr: newW = index newH = int(h * newW / w) print('h:{},newW:{},w:{},newH:{}'.format(h, newW, w, newH)) outfile = outPath + '/' + 'Icon-' + str(index) + '.png' out = img.resize((newW, newH), Image.ANTIALIAS) # resize image with high-quality out.save(outfile) print('output file ' + 'Icon-' + str(index) + '.png...') print('Export all ICONS finished...')
