Hi,
one common way to make labels stand out, other than halos (which are
often quite cheesy) is to trop a shadow, which looks especially good
if it's really small.
See the TypeBrewer online utility for an example (the major labels
have a tiny white shadow that they call highlight).
I would like to add that effect to our renderer. Rendering wise
it's trivial, what is not trivial is adding it to the API....
In theory I'd like to add the ability to parse the following:
<xsd:element name="Shadow">
<xsd:annotation>
<xsd:documentation>
A "Shadows" draws the same label with an offset and a different
color
</xsd:documentation>
</xsd:annotation>
<xsd:complexType>
<xsd:sequence>
<xsd:element ref="sld:Displacement" minOccurs="0"/>
<xsd:element ref="sld:Fill" minOccurs="0"/>
</xsd:sequence>
</xsd:complexType>
</xsd:element>
A shadow has a fill color, displacementX, displacementY.
Easy, end of story...
However, that also means adding a new interface, a new
implementating, and changing the style visitor interface
and all implementations. Sounds material for a proposal...
Bleck!!!
I don't see much of an alternative though... any bright idea?
Cheers
Andrea
