Hi Ed,
Yes, you can do it.
First, QU has a Poster function that enables you to divide an image between any number of sheets, no need to use and editor for non wrapped images.
However, to make each quadrant with it's own wrap, you don't really need 4 images with QU. It can be done in Qimage with 4 different image crops of one image made in the editor.
You could copy the image to get 4 copies, each with the appropriate crop but that is not necessary if you a prepared to print each quadrant individually.
A very accurate crop is possible in the editor because you are given a read-out of the pixel size as you do it.
Make the 1st quadrant crop apply the wrap border & print.
Then MOVE the crop to the next quadrant and print again -- and so on for all 4 quadrants.
I've done this in the past to make 4 panels but without a wrap.
You just need to work out the dimensions of the image print and wrap border to get it right.
I know that Fred & Terry like challenges
easy peasy
