Not all PointSymbolizer attributes accessible

[samueltc]

File, width, height and type should be accessible.

p = PointSymbolizer() dir(p)

['class', 'delattr', 'dict', 'doc', 'getattribute', 'hash', 'init', 'instance_size', 'module', 'new', 'reduce', 'reduce_ex', 'repr', 'setattr', 'str', 'weakref', 'allow_overlap']

r743 added:

PointSymbolizer().get_opacity
PointSymbolizer().set_opacity

What remains to be exposed in the python properties are the symbol file path, and sizes AFAICT.

Non essential properties, so I'm pushing off to 1.0.0

filename property patch

[mishok13]

Tada! Added filename property to PointSymbolizer. Dane, could you take a look at the patch? It looks kinda hackish to me.

[springmeyer]

Ya, the normal boost way would be to do something like:

        .add_property("filename",
            make_function(&point_symbolizer::get_filename,return_value_policy<copy_const_reference>()),
            &point_symbolizer::set_filename)

but that does not seem to work ad I'd expect due to the subclassing going on with symbolizer_with_image. So I'll need to look into this a bit more.

[springmeyer]

I still don't understand why the normal method mentioned above does not work, but your patch does and the set method does as well, so let's go with it.

applied your patch in r1295 - thanks!
