""" writeGif(filename, images, duration=0.1, repeat=True, dither=False,
nq=0, subRectangles=True, dispose=None)
Write an animated gif from the specified images.
Parameters
----------
FP : the file pointer -
images : list
Should be a list consisting of PIL images or numpy arrays.
The latter should be between 0 and 255 for integer types, and
between 0 and 1 for float types.
duration : scalar or list of scalars
The duration for all frames, or (if a list) for each frame.
repeat : bool or integer
The amount of loops. If True, loops infinitetely.
dither : bool
Whether to apply dithering
nq : integer
If nonzero, applies the NeuQuant quantization algorithm to create
the color palette. This algorithm is superior, but slower than
the standard PIL algorithm. The value of nq is the quality
parameter. 1 represents the best quality. 10 is in general a
good tradeoff between quality and speed. When using this option,
better results are usually obtained when subRectangles is False.
subRectangles : False, True, or a list of 2-element tuples
Whether to use sub-rectangles. If True, the minimal rectangle that
is required to update each frame is automatically detected. This
can give significant reductions in file size, particularly if only
a part of the image changes. One can also give a list of x-y
coordinates if you want to do the cropping yourself. The default
is True.
dispose : int
How to dispose each frame. 1 means that each frame is to be left
in place. 2 means the background color should be restored after
each frame. 3 means the decoder should restore the previous frame.
If subRectangles==False, the default is 2, otherwise it is 1.
