[mapguide-users] trouble replicating interstate symbol definition

Thu Aug 7 12:48:38 EDT 2008

I created the symbols outside of Studio using a text editor and then
loaded them into the server.  I will say that the first attempt or two
at using online encoders to base64 didn't work the file was radically
different that what was shown below.  I did hit on one that worked well,
I have it bookmarked but I don't have access to that bookmark right now.
You can look at the symbols created by the xml below by going to
http://gis.edsi/com then follow the links to the Mecklenburg County
public site.

Thanks,

Martin

I have been using Studio to create my symbol definitions, and in its
current form, your symbol gave an error. However, removing the
<SimpleSymbol> and <RenderingPass> tags allowed me to save the symbol
definition. Yet, I got the same result with this--nothing showed up on
screen when I created the line. So, I tried substituting this into a
<CompoundSymbolDefinition> along with some lines drawn representing a
road, and only the road lines showed up on screen.

I have tried encoding my image as well, using a site I found that
converts a file to base64, and that hasn't worked for me either. 
One question though: when I encoded my image, the base64 string was a
lot longer, probably 10x or more as long. Does that seem normal? The
image itself is under 6k.

Thanks for your help.

As far as I know, yes. So far, I have had all other composite symbols I
have created work for me. But this is the first one where I am trying to
include an image in the symbol, and I have apparently not figured out
how that is supposed to work.

Just wondering aloud here...are composite symbol definitions supported
in 1.2?  I know I have them working in 2.x.

Thanks,

Has anyone else tried to implement interstate signs?

Thanks.

yellow

MGOS
