Refactor the following python code. Increase the readability of the code by having one function for every action. One function that handles Resize Images, one for Analyze Images, one for Find Color Images, one for Check For Corrupted Files, one for Automatic Color Correction and one function for Automatic Color Correction + Resize (in that case have the function refer to the automatic color correction and than the resize function). Do not split the code into to many functions if not necessary. This should change the structure so that the def process_file and def process_folder functions can be deleted. In the actions field use the new functions. Remember one function per action. Also build utility functions where necessary with common code logic to reduce redundancies. Use easy names like resize_images for the functions. Code: import ctypes
