[mapguide-users] Custom Symbols...

Here is some more information, from Walt, who is more familiar with that code.
================
Here's what I think is happening. The repeat for his shield symbol is set to 100 mm in device units. As you zoom out the length of the polyline features get shorter (in device units). Eventually none of them are longer than 100 mm, and so no more shield symbols are drawn.
An ideal way to handle this is to change the shield symbol's LineUsage.UnitsControl to "Parametric", and then specify StartOffset / EndOffset / Repeat parametrically. But we haven't yet implemented support for the UnitsControl parameter.
Another way he might be able to handle this is to set the Offsets / Repeat to an expression based on the length of each feature. Maybe he has a length attribute in his data set? Or does the new ExpressionEngine offer an intrinsic Length function?
A final workaround is to create multiple scale ranges, and adjust the Offsets / Repeat to appropriate values for each range.
================
Hope this helps.
