This python package (availabe on PyPI athttps://pypi.org/project/numpngw/) defines the functionwrite_pngthat writes a numpy array to a PNG file, and the functionwrite_apngthat writes a sequence of arrays to an animated PNG (APNG) file. Also included is the classAnimatedPNGWriterthat can...
Create an array (a) of shape 3, 4, 8 (K=3, J=4, I=8). tidx is an array of the same length as a.shape[1], i.e. contains J = 4 elements where each index denotes which element of K should be chosen. Write a NumPy program to select from the first axis (K) by the indi...
