最近，该公司有了新的要求，要精简代码。这个博客记录了如何压缩图片。
[En]
Recently, the company has a new requirement to slim down the code. This blog records how to compress pictures.
原则：
[En]
Principle:
编写一个脚本，遍历图片文件夹‘.xcsets’中的所有文件，然后使用第三方算法压缩图像并将其替换回来。
[En]
Write a script that traverses all the files in the picture folder ‘.xcassets’, and then uses a third-party algorithm to compress the images and replace them back.
结果：
[En]
Results:
由于项目中的PNG图像已被压缩，这次只压缩了后缀为JGP的图片。由此可见，它仍然有效。
[En]
As the png images in the project have been compressed, this time only the pictures with the suffix jgp are compressed. It can be seen that it is still effective.
代码如下：
[En]
The code is as follows:
import os
import tinify
import shutil
tinify.key = '5J54hg59ysAuhHFPxXB*******'
source_file = '/Users/user/Desktop/Hotel.xcassets'
dest_file = '/Users/user/Desktop/destimages'
def getPngFileNames(source_dir):
pngDicts = []
for (parent, dirnames, filenames) in os.walk(source_dir):
for filename in filenames:
if filename.endswith('.jpg'):
tempDict = {}
tempDict['name'] = filename
tempDict['path'] = os.path.join(parent, filename)
pngDicts.append(tempDict)
return pngDicts
def compressImages(uncompress_images):
for pngDict in uncompress_images:
source = tinify.from_file(pngDict['path'])
source.to_file(os.path.join(dest_file, pngDict['name']))
def replace_file(new_path, old_path):
pngs = getPngFileNames(source_file)
for name in os.listdir(new_path):
for pngDict in pngs:
if pngDict['name'] == name:
shutil.copyfile(os.path.join(new_path, name), pngDict['path'])
if __name__ == '__main__':
replace_file(dest_file, source_file)
# pngs = getPngFileNames(source_file)
# compressImages(pngs)
print('done')
