'''
Resize an image while keeping its original aspect ratio.
Return:
(1) the file size, width, height of the original image
(2) the file size, width, height of the resized image.
Parameters:
img_path: str. The file path to the original image.
resize_path: str. The file path where the resized image will be saved.
max_w (optional, default -99): int. If this variable is larger than 0, the image will be resized so that its width does not exceed max_w.
max_h (optional, default -99): int. If this variable is larger than 0, the image will be resized so that its height does not exceed max_h.
max_side (optional, default -99): int. If this variable is larger than 0, the image will be resized so that its width and height do not exceed max_side.
max_size (optional, default -99): int. If this variable is larger than 0, the image will be resized so its size does not exceed max_size.

'''
Calculate file size, width, height, aspect ratio, image size, image diagonal length, and file size scaled by image size.
