Method Detail

toReferencedEnvelope

public org.geotools.geometry.jts.ReferencedEnvelope toReferencedEnvelope(java.awt.Rectangle paintArea)

Description copied from class: MapBounds

Create a ReferencedEnvelope representing the bounds.

Specified by:

toReferencedEnvelope in class MapBounds

Parameters:

paintArea - the size of the map that will be drawn (at 72 DPI).

adjustedEnvelope

public MapBounds adjustedEnvelope(java.awt.Rectangle paintArea)

Description copied from class: MapBounds

Create a ReferencedEnvelope representing the bounds.

Specified by:

adjustedEnvelope in class MapBounds

Parameters:

paintArea - the size of the map that will be drawn.
