public ColoredShadingColors(ColoredShadingColors.ColorHelper[] colors)

Constructor to provide unique elevation cutoffs and colors.

Method Detail

setSlopeColorAdjustment

public void setSlopeColorAdjustment(int adj)

Set the color factor to subtract from the colors for level or negative slopes. Should be the same for each byte, or the colors will change drastically.

getSlopeColorAdjustment

getColors

public ColoredShadingColors.ColorHelper[] getColors()

Get an array of colors with elevation values.

setColors

public void setColors(ColoredShadingColors.ColorHelper[] clrs)

Set the list of ColorHelpers. The elevations of the ColorHelpers should be in order, from lowest to highest.

getColortable

public int[] getColortable()

Description copied from interface: ElevationColors

Get a colortable as an array of ints.

Specified by:

getColortable in interface ElevationColors

setWaterColor

public void setWaterColor(java.awt.Color water)

Set the color to use for water/invalid data, zero elevation.

getWaterColor

public java.awt.Color getWaterColor()

Get the color to use for water/invalid data, zero elevation.

getColor

public java.awt.Color getColor(int elevation,
                               Length units,
                               double slope)

Get the Color for the given elevation, with the provided units. The slope of the land, from the northwest to the southeast, is provided.

Specified by:

getColor in interface ElevationColors
