thanks, when implements function createArc with 3 point (center, point1,
point2), i send you the function and it's up to you insert example in guide.
But, one cuestion: I create geometry whit library jst, I render geometry as
follows:
- Create Geometry with GeometryFactory.
- Create Featuretype:
FeatureType polyType =
FeatureTypes.newFeatureType(typesNew, "circlefeature");
Feature polyFeature = polyType.create(new Object[] {
polygon});
- Render: Create MapLayer with FeatureCollection and style.
MapLayer layer = new
DefaultMapLayer(featureCollectionLine,style);
this is my way of creating and painting figures.
I crate CurveImpl of the package
org.geotools.geometry.iso.primitive.CurveImpl (gt2-geometry)
How render CurveImpl in MapLayer?
thanks.
