Hey Jukka,
It might be possible to detect that less than 5 polygons are touching at a
point and treat that particular area as through the features were adjacent
to get the behavior in the 0.4 version of the plugin. However, it would
complicate the code quite a bit and slow it down.
Regarding

Regarding packaging the plugin into a libfolder in lib\ext\ojmapcoloring-0.5,
I used to do that with the DB Query plugin, and prefer it also, but recent
versions of OJ don't load plugins unless they are in the lib\ext directory.

Hi ,
I was rather thinking that users could select the v. 0.4 path at their own risk
for example by checking a box “Disjoint colors” with a tooltip hint “Tries to
prevent same colors from touching at any point”. But that is not especially
important feature and I do like simple and fast
Hi Larry,
Version 0.5 colors now all the Finnish municipalities and all the multi-slice
pizzas which I digitized fine. However, I think that when there are at maximum
5 areas touching on one point the version 0.4 does better coloring. The new
version may give the same color for areas which
Well, no matter how many times you slice it, a pizza is always (mostly)
planar :-). The problem with map coloring occurs when you can't draw a
line on a plane from a fixed point on all features to a fixed point on
their adjacent features without the lines crossing. You have to lift the
lines off
Hi Larry,
I should have actually guessed what happened. There used to be 8 municipalies
sharing a common landmark but because of some fusions there are only 6 left now.
I tried to find a document that says that pizza is no more planar when it is
sliced into 6 pieces. However, I found some
Hey Michaël,
I was using intersect, and I tried crosses, but that didn't work. I'm
taking a look at relate now, although I'm having a hard time deciphering
DE-9IM.

I agree it is not very intuitive.
To solve the problem for homogeneous geometries (same dimension), I

Hey Jukka,
Just got a chance to look at this. The region that is not coloring is
interesting.
It's like a pizza sliced into six pieces, each touching at the point.
You can't color this portion of the map with only five colors without two
adjacent (maybe just adjacent at one point in the
Hi Larry,
Do you compute relations between geomeries with intersect predicate ?
I wonder if you could remove edges between polygons adjacent at one point
from the graph by using relate operator (which makes it possible to check
intersection dimension).

Wasn't sure if you figured out the problem yourself. :]
I will try to look at the data today. If I can repeat your problem we
should file a bug report at least.
