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.

adjustBoundsToNearestScale

public MapBounds adjustBoundsToNearestScale(ZoomLevels zoomLevels,
                                            double tolerance,
                                            ZoomLevelSnapStrategy zoomLevelSnapStrategy,

Description copied from class: MapBounds

Adjust these bounds so that they are adjusted to the nearest scale in the provided set of scales.

The center should remain the same and the scale should be adjusted

Specified by:

adjustBoundsToNearestScale in class MapBounds

Parameters:

zoomLevels - the list of Zoom Levels

tolerance - the tolerance to use when considering if two values are equal. For example if 12.0 == 12.001. The tolerance is a percentage

zoomLevelSnapStrategy - the strategy to use for snapping to the nearest zoom level.

geodetic - snap to geodetic scales.

paintArea - the paint area of the map.

dpi - the DPI.

getScale

Specified by:

getScale in class MapBounds

Parameters:

paintArea - the paint area of the map.

dpi - the dpi of the map

adjustBoundsToRotation
