setWrapLimit

public static void setWrapLimit(int wrapLimit)

Programmatically sets the number of wraps per direction the wrapping projection handlers will apply

getHandler

public static ProjectionHandler getHandler(ReferencedEnvelope renderingArea,
                                           CoordinateReferenceSystem sourceCrs,
                                           boolean wrap)
                                    throws FactoryException

Returns a projection handler for the specified rendering area, or null if not found

Parameters:

renderingArea - The area to be painted (mind, the CRS must be property set for projection handling to work)

wrap - Enable continuous map wrapping if it's possible for the current projection

Throws:

FactoryException

getHandler

public static ProjectionHandler getHandler(ReferencedEnvelope renderingArea,
                                           CoordinateReferenceSystem sourceCrs,
                                           boolean wrap,
                                           Map<String,Object> projectionParameters)
                                    throws FactoryException

Returns a projection handler for the specified rendering area, or null if not found

Parameters:

renderingArea - The area to be painted (mind, the CRS must be property set for projection handling to work)

wrap - Enable continuous map wrapping if it's possible for the current projection

projectionParameters - map of options for the projection handler, allows finer configuration of the handler from the final user of it

Throws:

FactoryException
