U Z$dPã@sGdd„dƒZddd„ZdS)c@s0eZdZdZdd„Zdd„Zdd„Zdd „Zd S) ÚIteratora- This class implements an iterator object that can be used to loop over an image sequence. You can use the ``[]`` operator to access elements by index. This operator will raise an :py:exc:`IndexError` if you try to access a nonexistent frame. :param im: An image object. cCs0t|dƒsd}t|ƒ‚||_t|jddƒ|_dS)NÚseekzim must have seek methodZ _min_frameé)ÚhasattrÚAttributeErrorÚimÚgetattrÚposition)ÚselfrÚmsg©r ú5/tmp/pip-unpacked-wheel-s9vr6rj9/PIL/ImageSequence.pyÚ__init__s  zIterator.__init__c CsBz|j |¡|jWStk r<}z t|‚W5d}~XYnXdS©N)rrÚEOFErrorÚ IndexError)r ÚixÚer r r Ú __getitem__&s  zIterator.__getitem__cCs|Srr )r r r r Ú__iter__-szIterator.__iter__c CsRz$|j |j¡|jd7_|jWStk rL}z t|‚W5d}~XYnXdS)Né)rrrrÚ StopIteration)r rr r r Ú__next__0s zIterator.__next__N)Ú__name__Ú __module__Ú __qualname__Ú__doc__r rrrr r r r rs  rNcs`t|tƒs|g}g}|D],}| ¡}|dd„t|ƒDƒ7}| |¡qˆr\‡fdd„|DƒS|S)a Applies a given function to all frames in an image or a list of images.
