<DIV>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.</DIV>

<P><FONT size=2>Hi Stefan,<BR><BR>See below response from Walt (developer / style guru)<BR><BR>For numbers 1 and 2, if you could put together reproducible test cases<BR>and submit as bugs, that would be great. This process is documented<BR>here:<BR><BR><A href="http://trac.osgeo.org/mapguide/wiki/SubmitTicket">http://trac.osgeo.org/mapguide/wiki/SubmitTicket</A><BR><BR>Jason<BR><BR>-----Original Message-----<BR>From: Walt Welton-Lair<BR>Subject: RE: [mapguide-internals] FW: [mapguide-users]<BR>Cartographicsymbolsproblems<BR><BR>Well, line styles with the new symbolization are not yet officially<BR>supported (i.e. there are bugs) You're right though - nice to see<BR>someone looking at this.<BR><BR>1 & 2 most likely bugs<BR><BR>3. All properties, including line thickness, are in millimeters. You<BR>won't see much difference between 0.12mm and 0.25mm - both probably one<BR>pixel.<BR><BR>4. This gives you a circle (using two arcs):<BR> <Geometry>M -1,0 A 1,1 0 1 1 1,0 A 1,1 0 1 1 -1,0</Geometry><BR> Here's what the parameters mean:<BR> - move to (-1,0)<BR> - arc to #1 (lower half of circle)<BR> x/y radii (1,1)<BR> x-axis rotation in degrees (0)<BR> use a large arc sweep (1)<BR> draw clockwise (1)<BR> end point (1,0)<BR> - arc to #2 (lower half of circle)<BR> ...<BR><BR>5.

Cool to see someone trying<BR>to use the new symbol stuff...<BR><BR>-----Original Message-----<BR>From: Stefan Dalakov<BR>Subject: [mapguide-users] Cartographic symbols problems<BR><BR>Hi all,<BR><BR>I have some problems with complex line styles. If anyone can help with<BR>information, a workaround or at least with information if this is a<BR>known problem.<BR><BR>1. When placing symbols along a line there are problems in displaying<BR>them. See attached screenshots.<BR>2. When selecting a feature with such styling only symbols are marked as<BR>selected, not the main line. I tried changing the order in the<BR>definition, but this does not help.<BR>3. Line thickness on screen changes incorrectly. If there are 2 lines<BR>with width 0.12 and 0.25, they are displayed with same thickness, next<BR>visibly different line is with 1.25 and is very thick.<BR>4. How to draw a circle - I could not find a document with description<BR>of parameters of A (arc to) option ?<BR>5. Is there a way to place symbols only at vertices of a line - I need a<BR>simple, solid line with a circle at every vertex?<BR><BR>Thank you in advance<BR>Stefan Dalakov<BR>_______________________________________________<BR>mapguide-users mailing list<BR>mapguide-users@lists.osgeo.org<BR><A href="http://lists.osgeo.org/mailman/listinfo/mapguide-users">http://lists.osgeo.org/mailman/listinfo/mapguide-users</A><BR></FONT></P></BLOCKQUOTE></BODY></HTML>
