This article example for you to share the python batch processing image specific code for your reference, the specific content is as follows
A company project requires all 4096x4096 pictures are converted into 2048x2048 pictures, this batch conversion of picture size software online a lot of my coworkers originally used the United States to see the batch conversion, but a little bit of trouble, each time you also need to specify the picture to be converted to the input path and the output path, and each time can only deal with a folder, it's very cumbersome! So I thought of the almighty Python, and then wrote a script to batch processing of pictures, the same root directory of all the folders of the sub-files, etc., all the pictures will be processed.
The code also adds a lot of exception catching mechanisms and hints, which I hope will be helpful.
Remarks:
1. Imported the PIL library, is used to deal with pictures, very powerful;
2. imported win32 library, is to determine the hidden files with our project needs to delete the hidden files, do not need to directly find the deletion.
3. import send2trash library, is the deleted files into the trash, rather than permanently deleted, this I just prevent the deletion of useful files and get, a little strict right, do not need to be deleted ah.
4. I this script is Python2.7 written, but in dealing with the Chinese encoding is very disgusting, although I finally solved the solution, this solution, I will then write a separate article, but at the moment I am recommending that we do not use the version of python. I've been told that the encoding problem has been solved in some versions of python. I hope you'll take my advice.
