I have been able to reproduce this problem with trunk.
It seems to occur for gap lengths that are longer than
the length of the line. In that case, the arrows are
rendered for each line segment from the middle of the
line to the end of the line. Slightly different
behaviour for 6.0 and trunk.
Dear Stephen,
We've checked that vertices of line are not coincide. Please check the
attached MapInfo file. It's the problematic part taken out from the
original map.

Dear Jackey Cheung,
I am not sure what exactly you are trying to achieve.
Your arrows seem to point in the direction of the lines.
The topmost arrow in figure 1 is placed at a strange
position - is that the problem?
Some comments:
The result shown in image 2 is expected. The arrow
symbols are
Thanks for your comment, Havard Tveite.
As you suspected, the strange position (and also redundant) of arrows
is problem in figure 1. Since there is only one line there, we expect
only one set of (around 2~3) arrows were rendered. We can't figure out
why there are redundant arrows rendered at
Jackey,
I have seen this problem before and I think it is related to the fact
that you might have coincident points in your line. For example if the
first and second point in the linestring have the same value. This
causes problems when we try to compute the heading for that segment. If

Hi all,
We are trying to render line direction on 6.0.1. However, there are
something weird with it.
