Convert PIL Image to byte array?

Question

I have an image in PIL Image format. I need to convert it to byte array.

img = Image.open(fh, mode='r')   roiImg = img.crop(box) 

Now I need the roiImg as a byte array.

Answer 1

Thanks everyone for your help.

Finally got it resolved!!

import io  img = Image.open(fh, mode='r') roi_img = img.crop(box)  img_byte_arr = io.BytesIO() roi_img.save(img_byte_arr, format='PNG') img_byte_arr = img_byte_arr.getvalue() 

With this i don't have to save the cropped image in my hard disc and I'm able to retrieve the byte array from a PIL cropped image.

Answer 2

This is my solution.Please use this function.

from PIL import Image import io  def image_to_byte_array(image:Image):   imgByteArr = io.BytesIO()   image.save(imgByteArr, format=image.format)   imgByteArr = imgByteArr.getvalue()   return imgByteArr
