Add support to dynamic symbols.

[v@…]

I'd like to see a SymbolObj in PHP/Mapscript.

I need to create symbology on the fly, and this would be very helpful to avoid 
messing with new symbolfiles, etc.

This is a very legit request, but unfortunately given our long list of 
priorities I'm not sure we can make this happen for 3.7.  I just wanted to warn 
you in advance... but if we can find time to do it then we will.

No time in 4.0, let's try to do this in 4.1

PHP/Mapscript has now a support for createing and setting a symbol object. 
Please refer to the README for details.

Meking this bug as Fixed.

I don't believe SWIG/MapScript has been updated though. Re-opening bug until 
that can be confirmed. The implementations should match as well.

Nice catch, Steve.  :)

I'm working on this in SWIG mapscript under issue 579.

Steve, you want the implementations to match, and I'm doing my
best, but there is one break that I am making.

PHP-mapscript has setpoints() and getpointsarray() that use
arrays of x, y values.  Now, arrays are problematic for SWIG
since they require a different implementation for every
language.  So we're not using arrays in the SWIG mapscript,
but are instead using lineObj for the POINTS of a vector
symbol.  Makes good syntactic sense as well, IMO.

You can see the API for the new classes and methods as they
develop in mapscript/doc/mapscript.txt or online at

I believe this bug was reopened for Sean to update SWIG. Has this been done?

[sgillies@…]

Yes, SWIG mapscripts have had dynamic symbols since 4.2.0.

[dmorissette]

Marking fixed then.
