Image cropping is very easy using python library Pillow. Following is simple program to crop image in required parts.
Most important part of cropping is to know pixel size of your image, you can crop required portion using .crop method of Image module of Pillow.

| image_name_output = '06_crop_image_01_output_01.jpg' | |
| im.save(image_path_output + image_name_output) | |
| print('im.size', im.size) | |
| ###################################################### right half of the image | |
| im = Image.open(image_path_input + image_name_input) | |
| im = im.crop((im_width/2, 0, im_width, im_height)) | |
| image_name_output = '06_crop_image_01_output_02.jpg' | |
| im.save(image_path_output + image_name_output) | |
| print('im.size', im.size) | |
| ###################################################### right top half of the image | |
| im = Image.open(image_path_input + image_name_input) | |
| im = im.crop((im_width/2, 0, im_width, im_height/2)) | |
| image_name_output = '06_crop_image_01_output_03.jpg' | |
| im.save(image_path_output + image_name_output) | |
| print('im.size', im.size) | |
| print('*** Program Ended ***') |
Please note that crop takes tuple having four values as input. These four values represent left, upper, right, lower point .
Original image
Left Half of the image
Right Half of the image
Top Right corner of the image
Here is the output of the program, please note the pixel size of each cropped image.
$ python3.6 06_crop_image_01.py *** Program Started *** im.size (1920, 1318) im.size (960, 1318) im.size (960, 1318) im.size (960, 659) *** Program Ended ***
