The heart on the left in the example shown was done in another program (Affinity Designer) and shows perfect proportionally spaced borders in nest format.
The heart on the right was achieved by copying the shape a few times, enlarging each one separately and then centering them.
As can be seen, the simple copy & resizing is not a pretty result. It's the same with rectangles and other vector shapes.
Is there a way to achieve the result in PSP (I have 2023) that doesn't involve algebra? ?
