I know I can resize a image with ImageMagick using 
But I want to have exactly the same number of pixels with exactly the same values in exactly the same order, but they will be *"re-flowed"* if that is a word into a different shape.
I have already worked out how to do it with Python Imaging Library and Numpy. My starting image is 80x80 and looks like this:
from PIL import Image
import numpy as np
image = Image.open('a.png').convert('RGB')
npArray = np.array(image)
Image.fromarray(npArray.reshape(-1,160,3)).save('largeur160.png')
Image.fromarray(npArray.reshape(-1,40,3)).save('largeur40.png')
Image.fromarray(npArray.reshape(-1,10,3)).save('largeur10.png')
I get these images with width 160, and 40 and 10:
-resize or -scale, but how can I ***reshape*** a image with ImageMagick? If I use -resize or -scale:
magick image.png -resize 160x a.png
magick image.png -scale 160x b.png
I will get this:
