Yes it would help to get the underlying SymbolDef xml. Sometimes it is possible
to massage those to work around some of the bugs. This is particularly true in
the case of line styles.

Hi Stefan,
See below response from Walt (developer / style guru)
For numbers 1 and 2, if you could put together reproducible test cases
and submit as bugs, that would be great. This process is documented
here:

Cartographicsymbolsproblems
Well, line styles with the new symbolization are not yet officially
supported (i.e. there are bugs) You're right though - nice to see
someone looking at this.
1 & 2 most likely bugs
3. All properties, including line thickness, are in millimeters. You
won't see much difference between 0.12mm and 0.25mm - both probably one
pixel.
4. This gives you a circle (using two arcs):
<Geometry>M -1,0 A 1,1 0 1 1 1,0 A 1,1 0 1 1 -1,0</Geometry>
Here's what the parameters mean:
- move to (-1,0)
- arc to #1 (lower half of circle)
x/y radii (1,1)
x-axis rotation in degrees (0)
use a large arc sweep (1)
draw clockwise (1)
end point (1,0)
- arc to #2 (lower half of circle)
...
5. This will eventually be supported
Walt

Any of you have any insight into this one? Cool to see someone trying
to use the new symbol stuff...

Subject: [mapguide-users] Cartographic symbols problems
Hi all,
I have some problems with complex line styles. If anyone can help with
information, a workaround or at least with information if this is a
known problem.
1. When placing symbols along a line there are problems in displaying
them. See attached screenshots.
2. When selecting a feature with such styling only symbols are marked as
selected, not the main line. I tried changing the order in the
definition, but this does not help.
3. Line thickness on screen changes incorrectly. If there are 2 lines
with width 0.12 and 0.25, they are displayed with same thickness, next
visibly different line is with 1.25 and is very thick.
4. How to draw a circle - I could not find a document with description
of parameters of A (arc to) option ?
5. Is there a way to place symbols only at vertices of a line - I need a
simple, solid line with a circle at every vertex?
Thank you in advance
Stefan Dalakov
