自动生成Android不同分辨率下的图片

Android屏幕分辨率适配的图标处理比较麻烦，让UI做不同尺寸的图片也挺浪费时间的，并且容易出错，于是用Python写了个工具自动化处理图片，UI只需要做好1080*1920分辨率下的图片就可以了，其它分辨率的图片自动生成。

import os.pathimport sysfrom PIL import Image"""自动生成不同分辨率下的App图片UI设计1080*1920分辨率图片，放在drawable-xxhdpi目录下，自动生成其它的分辨率图片"""__author__ = [‘"Xitao":<offbye@gmail.com>’]def image_resize(img_file, target, percent):"""resize image and save to target path:param img_file: image file path:param target: save path:param percent: resize percent:return:"""img = Image.open(img_file)print(img.size)width, height = img.sizetarget_img = img.resize((int(width * percent), int(height * percent)), Image.ANTIALIAS)target_img.save(target)img.close()target_img.close()print(" save target image to " + target)def path_resize(src, target, percent):if not os.path.isdir(src):print(src + " must be a dir")return -1os.chdir(src)cwd = os.getcwd()dirs = os.listdir(cwd)for file_name in dirs:print file_nameif file_name.endswith(‘.9.png’):continuesrc_file = os.path.join(cwd, file_name)if not os.path.exists(target):os.mkdir(target)image_resize(src_file, target + ‘/’ + file_name, percent)def android(res_dir):xxhdpi_path = res_dir + "/drawable-xxhdpi/"if not os.path.isdir(xxhdpi_path):print("xxhdpi_path must be a dir")return -1path_resize(xxhdpi_path, res_dir + ‘/drawable-xhdpi’, 0.667)path_resize(xxhdpi_path, res_dir + ‘/drawable-hdpi’, 0.444)path_resize(xxhdpi_path, res_dir + ‘/drawable-mdpi’, 0.296)if __name__ == "__main__":print(‘please input your androd res dir path’)print(sys.argv)if sys.argv[1]:android(sys.argv[1])
