I’m an artist with a stupid question, the answer to which might easy…

I have need of a process that can segment an image into a specified number of equal-sized tiles, that will then go through a separate image processor (it can't handle large files in one go; splitting them up into discreet tiles allows this), to be stitched-back together later (I was going to use PhotoStitcher or something like it).

Any ideas as to how to achieve this? I have racked my brains without an answer!

Thanks, guys

    That sounds horribly messy & most probably an XY Problem ... what type of image files? How big is the image? What process are you trying to achieve that cannot be done to a whole image? – Tetsujin Jul 27 '17 at 9:11

    Looks like imagemagick could probably do this, but it's a bit of a faff to install if you're not already using MacPorts or Homebrew. There are third-party apps offering similar functionality, e.g. Tile Photos FX (never used it and have no opinion on it). The cropping capability of the built-in sips command may also be of use, but would require some bash- or Apple-scripting to generate every tile. – calum_b Jul 27 '17 at 9:44
