a-cv2-imshow-thread

Solution for the "window - not responding" problem with cv2.imshow()

pip install a-cv2-imshow-thread

    Usage:



    import glob

    import os

    from a_cv2_imshow_thread import add_imshow_thread_to_cv2 

    add_imshow_thread_to_cv2() #monkey patching

    import cv2

    image_background_folder=r'C:\yolovtest\backgroundimages'

    pics=[cv2.imread(x) for x in glob.glob(f'{image_background_folder}{os.sep}*.png')]

    cv2.imshow_thread( image=pics[0], window_name='screen1',sleep_time=None, quit_key='q') #single picture

    cv2.imshow_thread( image=pics, window_name='screen1',sleep_time=.2, quit_key='e') #sequence of pics like a video clip



        Parameters:

            image: Union[list, np.ndarray]

                You can pass a list of images or a single image

            window_name: str

                Window title

                (default = "")

            sleep_time: Union[float, int, None] = None

                Useful if you have an image sequence.

                If you pass None, you will have to press the quit_key to continue

                (default = None)

            quit_key: str = "q"

                key to close the window

        Returns:

            None
