First, create a NumPy array representing the image data you want to save. You can generate this array or load it from your data source. For the sake of this example, we’ll create a simple grayscale image array: image_data=np.array([[0,128,255],[64,192,32],[100,50,150]],dtype...

which can convert an N-D array to a linear 1-D array. Both these methods perform the same functionality. The difference is that theravel()method returns a reference view of the array and affects the original array, whereas theflatten()method works on a copy of the array. Due to this,...
