[mapguide-users] Custom Symbols...

[Martin Morrison]

Ok, next question...

I have the symbols working, they look great.  The road symbols just turn
off when I zoom out past about 7000 even though the road still shows up
with it's style.  I don't see a parameter that controls how far in and
out the symbol displays.  Where should this be changed at?

Thanks,
Martin

Hi Martin,

You are using incorrect format for the Content tag. The
"data:image/png;base64," piece is not necessary, just the png content
converted to base64.

Here is an example of correct usage:

<?xml version="1.0" encoding="UTF-8"?>
<SimpleSymbolDefinition

I'm trying to embed a PNG into a custom symbol.  When I use the code
below I get the error shown at the bottom.  If I remove this section it
works (without my PNG of course).  How should the <IMAGE> tag be used?
Any clues?

Thanks,
Martin
