- Description copied from interface:
ExternalGraphicFactory
- Turns the specified URL into an Icon, eventually using the Feature
attributes to evaluate CQL expressions embedded in the url.
The size
parameter defines the size of the image (so that
vector based symbols can be drawn at the specified size directly), or may
be zero or negative if the size was not specified (in that case the "natural" size of
the image will be used, which is the size in pixels for raster images, and
16 for any format that does not have a specific size, according to the SLD spec).
null
will be returned if this factory cannot handle the
provided url.
