You can use the ``[]`` operator to access elements by index. This operator will raise an :py:exc:`IndexError` if you try to access a nonexistent frame. :param im: An image object. z Image.Image)imcCs0t|dsd}t|||_t|jdd|_dS)Nseekzim must have seek methodZ _min_framer)hasattrAttributeErrorrgetattrposition)selfrmsgr5/tmp/pip-unpacked-wheel-xela2va7/PIL/ImageSequence.py__init__$s  zIterator.__init__int)ixreturnc CsJz|j||jWStk rD}zd}t||W5d}~XYnXdS)Nend of sequence)rrEOFError IndexError)r rerrrr __getitem__+s  zIterator.__getitem__)rcCs|S)Nr)r rrr__iter__3szIterator.__iter__c CsZz$|j|j|jd7_|jWStk rT}zd}t||W5d}~XYnXdS)Nrr)rrr r StopIteration)r rrrrr__next__6szIterator.__next__N)__name__ __module__ __qualname____doc__rrrrrrrrrs  rNzImage.Image | list[Image.Image]z+Callable[[Image.Image], Image.Image] | Nonezlist[Image.Image])rfuncrcs`t|ts|g}g}|D],}|}|ddt|D7}||qr\fdd|DS|S)a Applies a given function to all frames in an image or a list of images.
