Thanks both, very helpful!

If I wanted to adjust that so that I only have say a 32px overlap between crops, how would I manage it?

I tried but this results in a command that takes a very long time to run.

Sorry, yes that's correct, shifting by X not Y so +1+0.

Ok, I guess I'll have to do it with a script. I'm not quite sure what you mean by the second part. Could you give an example command? Surely if I do the 256x256 crop and then roll it I will go outside of the newly cropped area?

My image is 30000x256px. I want to create 30k 256x256px images using a crop every 1px horizontally.

So first crop is 256x256+0+0
Second crop is 256x256+0+1
...

convert original.png -crop 256x256 segments/segment.png

This gets me part of the way there in that it gives me a crop every 256px. But ...

The artefacts I mean are the 1px columns that appear every 20px or so and don't fit in the sequence.

But +append has solved it, thank you! I have the full image now.

What I have - image with whitespace at top and bottom

What I want - image with no whitespace and content is distorted to fit space. This was done in photoshop
