[nbos] [req] expanded path constructionkeith.davies-at-kjdavies.orgThu Jun 25th, 2009
FM8 allows the user to combine polygons (using, oddly enough, the
Combine Polygons entry in the Actions menu). You can add, subtract, and
XOR the polygons.
Is there any chance you'd add the last set function? Intersect would
be really useful sometimes. It can be simulated with the existing
C = A && B = (A || B) ^^ (A - B) ^^ (B - A)
but doing that every time, especially when chunking up an existing
polygon, would get rather expensive.
Mind you, selective use of the polygon floodfill might actually do a
better job of this. Hide everything that might interfere with the fill
(such as rivers and various symbols), use a conflicting color (for pen,
leave brush/fill clear) to draw the region you want to intersect, then
fill. Grab the new polygon, delete the working one, done.
Easier than trying to use the Flush Against feature -- which also is a
cool addition, but somewhat tricky.
