Hello stylers,
Things are cleaning up. The rendering and persistance issues have been
solved. This will allow you to actually program properly the against
the new api tommorow.
Translation we had a style workflow review.
The plan is to break out the bit that edits a SLD Symbolizer as a
separate extension point.
- A simple user interface will be constructed that focuses on *one*
FeatureTypeStyle and a *Single* Rule
- In the medium term we will look at breaking out the common case of
styling based on a attribute. (This is an example where multiple rules
are present, but the generation of the rules can be wrapped up in a nice
user interface)
Attribute: speed
Symbol Label Value
[] Slow 0-30
[] Town 30-50
[] Hiway1 50-70
[] Hiway2 70-90
[] Freeway 90+
- A more complicated user interface (like the one James sent us a screen
snapshot of) can be constructed at a later time.
The user interfaces we make now for Symbolizer editing can be reused in
the future where multiple rules are present.
It would be nice if the geotools AttributeType model provided such
information as min/max for numeric content, or a valid set for
qualitative data. This user interface would use sensible defaults taken
from the ColorBrewer project. Before I approach them with the request -
has anyone heard of this information being available in a FeatureType
model? I know how to ask such questions in SQL, perhaps an alternate
request would be for min/max functions?
For those concerned about full SLD support - you can drag a SLD file
onto a layer. I imagine a text editor on the SLD content could also be
made available.
The current renderer has two known rendering problems:
- it is willing to try rendering a LineString with a Polygon Symbolizer
- the text label resolution technique produces a internal JTS error
