Best way to accomplish "edge striping," but with a tile/bitmap fill?
I'm making a parchment style map, and I'd like to shade the areas around the coastline with a pen-and-ink hatching fill. So far I haven't been able to figure out a tool or command to do this in CC3+, but would love advice or insights on what might work.
The look I'm going for is essentially what you'd get if you took the polygon region that edge striping creates, but just filled it with a tileable bitmap texture (in this case, a hatching pattern) rather than radiating out a filter ray orthogonal to the coastline.
Things I've tried that DON'T work include:
-- Edge striping. This marks off the right polygonal area surrounding the land mass, but I can't simulate a texture fill using the striping filters.
-- Draw / Offset. Not the intended use case, obviously, but thought I'd see what happens trying to "trace around" an existing closed polygon entity rather than an open line/curve. No dice.
-- Scaling out the polygon on a lower sheet. If I could get the right shape polygon on a different sheet, I'd just tile it in behind the landmass. And this would work great for a simple geometry, but my landmasses aren't simple, so the capes/bays/etc. don't line up between the original and scaled versions.
Currently my best solution is to move over to GIMP, select my landmasses one by one, convert each selection to Border, then fill the resulting border selection with a hatching pattern and put that on a drawing layer behind my original landmasses. That's certainly better than hand-tracing every coastline, but I was hoping to find something a little more automated (a la edge striping) and ideally within CC3+. Any thoughts?
