Constructor Detail

BarScaleUI

public BarScaleUI(processing.core.PApplet p,
                  UnfoldingMap map,
                  float x,
                  float y)

BarScaleUI

public BarScaleUI(processing.core.PApplet p,
                  UnfoldingMap map)

Method Detail

draw

public void draw()

Draws a bar scale at given position according to current zoom level. Calculates distance at equator (scale is dependent on Latitude). Uses a distance to display from fixed set of distance numbers, so length of bar may vary.

setStyle

public void setStyle(int color,
                     int barWeight,
                     int barCapOffset,
                     processing.core.PFont font)

Set the style of the bar scale.

Parameters:

color - the color of the scale.

barWeight - the weight of the scale.

barCapOffset - the offset of the scale.

font - the font to use for the bar scale.

getClosestDistance

protected float getClosestDistance(float distance)

Returns the nearest distance to display as well as to use for calculation.

Parameters:

distance - The original distance

Returns:

A distance from the set of DISPLAY_DISTANCES

closest

protected float closest(float of,
                        java.util.List<java.lang.Float> in)
