The effect can also use an ordinary png image to generate the displacement.

Not being a technical person I can't explain the exact maths, but the visual appearance of the image or normal map should give you an idea of what the displacement will look like.

I love it :)

Might need a few place names, but nothing too 'shouty' or it will overpower the map.

I had this problem myself not that long ago, and it was caused by the lack of a map note.

If you open the map notes |CC2NOTES| there should be one there called "Resize".

If its not there create a new map note and call it Resize

Ok will bring up an Edit Text box, into which you need to type the command "Stretch".

Ok makes everything vanish, but if you open the map notes again you will see the Resize map note has been added.

Now try resizing your map again.

I agree! I can't see much difference, but I also prefer A. It's thinner, isn't it?

Looks like you're really getting on well.

Another way to do it is to keep the plain white fill and put the parchment over the top of everything else and use a Blend Mode sheet effect set to Multipy 100% on that sheet. It's how I add parchment texture to other black and white styles.
