Array2GIF provides a single top-level function, write_gif(), to write a 3-D NumPy array to a GIF, or a list of these arrays to an animated GIF. It works for me - just small animations of thermodynamics simulations - like the magnetization in the Ising model shown here.
Usage
Here is an example for a 2 pixel by 3 pixel animated GIF with two frames, switching 5 frames per second. All animations from this library will loop indefinitely.
import numpy as np
from array2gif import write_gif
dataset = [
np.array([
[[255, 0, 0], [255, 0, 0]], # red intensities
[[0, 255, 0], [0, 255, 0]], # green intensities
[[0, 0, 255], [0, 0, 255]] # blue intensities
]),
np.array([
[[0, 0, 255], [0, 0, 255]],
[[0, 255, 0], [0, 255, 0]],
[[255, 0, 0], [255, 0, 0]]
])
]
write_gif(dataset, 'rgbbgr.gif', fps=5)
# or for just a still GIF
write_gif(dataset[0], 'rgb.gif')Installation
Either:
pip install array2gif
or:
pip install git+https://github.com/tanyaschlusser/array2gif.git#egg=array2gif
Release History
1.0.4 (2018-06-22)
Bugfixes
Fixed issue where error was raised when non-integer dataset is used: instead now it is cast to uint8 and a warning is raised if there’s a difference between the two images.
Addressed issue where no error is raised when there are more colors than possible in a GIF (256 max). Although it is possible to have a separate palette for every single frame, this is not implemented right now, and the initial global palette is used for the entire animation.
1.0.3 (2018-06-02)
Bugfixes
Did not bump version in documentation last times.
1.0.1 (2018-06-02)
Bugfixes
Fixed issue where the width and height of an image are swapped. This is clear in image editors but was not obvious when viewed in Chrome.
1.0.0 (2018-05-23)
Improvements
It is now possible to use PIL ordering of data (rows x cols x rgb) in addition to the original ordering (rgb x rows x cols).
Bugfixes
Fixed issue where array2gif would raise ValueError when using a 4D NumPy array with perfectly valid data. Now it is possible to use either a list of 3D NumPy arrays, or a 4D NumPy array for animated gifs.
0.1.0 (2016-09-30)
Initial release
One single function, write_gif.
