Given this image of a jigsaw with 4 pieces, is there a technique to alter the shapes so they shrink away from each other but retain their interlocking nature?
I would describe it as dissolving or receding the edges, or adding a tolerance between the pieces.
Bumping up the stroke width gives me the visual result of creating a void between the pieces, but I'm looking to actually alter the underlying shapes. Ideally looking for a technique that will scale with more pieces.
EDIT: Just in case the SVG is not well visible in your browser, here's a screenshot of the image. The fill colors are selected randomly:
