[Cut shapes with lines]

Thanks, this looks like it will work.

But I am getting two different non-ideal results.

If I use the subtract method, any changes I made to the size of the image are reset when I do the subtraction. This is solved by simply having the image be exactly the right size on import. But it would be good to be able to adjust it.

The other is that with the divide method I have to clean up the old lines that are left there.

 

In any case, the first subtraction method is workable. It would be good if I could resolve the scaling issue but fine if I can't. Thanks!

 

[Cut shapes with lines]

I have a workflow which requires me to take an image, overlay a set of lines or shapes, then slice, pull apart and arrange that image.

For example, see the attached image.

I would like to use those lines to slice the yellow square, then drag apart and arrange the resulting fragments of the square. (though in reality I would be using a JPG as a fill instead of a yellow square)

I am trying to convert over from Illustrator. There I could select all the shapes at once and as long as the square was the lowest layer, I could use the divide operation in the pathfinder to get the desired result. In Affinity Designer I can get a single division to work, but no more than that and it seems to only work once. Then it is converted into a curve and no longer divides as expected.

A typical image would have on the order of 200-500 pieces it would be divided into so this needs to be something that I can do quickly and efficiently.

Hopefully I am just missing an obvious divide setting or cut tool somewhere.
