Crop before converting to JPG

[mansi-aggarwal-2504]

Hello! First of all, thank you for this repository.
I am using some ARW images for object detection. I want to fetch the detected objects from the ARW images and I need to further carry out an object detection task on the cropped images.
But since PIL and opencv can't read ARW format files, I have to convert the images to JPG first and then crop out the bounded objects which reduces quality. I tried Imaging Edge software and it gives me better resolution of the cropped images but it's a tedious task and I want to automate the process.
Is there anyway I can use arwjpg and before converting the images, I can use the bounding boxes (available in xml format) and crop out certain parts of the images and then convert the cropped portions to JPG?
