ImageMagick crop huge image

Question

I am trying to create tiles from a huge image say 40000x40000

i found a script on line for imagemagick he crops the tiles. it works fine on small images like say 100

Answer 1

ImageMagick is simply not made for this kind of task. In situations like yours I recommend using the VIPS library and the associated frontend Nip2

VIPS has been designed specifically to deal with very large images.
