Constructor Detail

SLDRenderedGeometries

public SLDRenderedGeometries(GeometryCollection geometry)

Construct a layer for the specified geometry.

Parameters:

geometry - The geometry, or null if none.

See Also:

RenderedGeometries.setGeometry(org.geotools.renderer.geom.GeometryCollection)

Method Detail

paint

protected void paint(RenderingContext context)
              throws org.opengis.referencing.operation.TransformException

Draw the geometry.

Overrides:

paint in class RenderedGeometries

Parameters:

context - The set of transformations needed for transforming geographic coordinates (longitude,latitude) into pixels coordinates.

Throws:

org.opengis.referencing.operation.TransformException - If a transformation failed.

Task:

REVISIT: The scale computation done here is inacurate. It uses only the scale along X axis, fails under rotation, ignore the physical device size and do not comply to the usual definition of map scale (for example 1:10000 meaning "10000 meters in the real world = 1 meter on the screen"). A more accurate scale would be Renderer.getScale().

paint

protected void paint(java.awt.Graphics2D graphics,
                     java.awt.Shape shape,
                     Style2D style)

Invoked automatically when a polyline is about to be draw. This implementation paints the polyline according to the rendered style

Overrides:

paint in class RenderedGeometries

Parameters:

graphics - The graphics in which to draw.

style - The style to apply, or null if none.

shape - The polyline to draw.
