How to process an image through CV2?

Question

Python

I take a screenshot of the screen and convert its image to a different color space. I need to create a new image without saving it to disk, and then work with it.
How to do?
I tried like this:

image = pyautogui.screenshot(region=(514, 495, 264, 12))
    image = cv2.cvtColor(np.array(image), cv2.COLOR_BGR2GRAY)
    im=Image.fromarray(image, 'RGB') # Выдает ошибку ValueError: not enough image data
    #cv2.imwrite("pic.png", image) так я делал раньше, но мне надо без создания файла
    #im = Image.open('pic.png')
  
    for i in range(1, 11):
        if i == 10:
            im_crop = im.crop((244, 1, 264, 12))
        else:
            im_crop = im.crop((jump * (i - 1)+2, 1, 27 * (i - 1) + 16, 12))

Answer 1

It's not clear what exactly you are trying to do. If you just translate the screenshot into a different color space ,
then these two lines enough. Further, it is better to do crop using cv2, since numpy arrays are enough for this (namely, this is how cv2 stores images).
