Class ColorMap

java.lang.Object

net.nullved.pmweatherapi.util.ColorMap

public class ColorMap
extends Object

A builder-based representation of ColorTables. Should hopefully be able to produce identical results.

You can create a new ColorMap builder with ColorMap.Builder.of(Color). Use ColorMap.Builder.addPoint(Color, float) to add a new point to lerp between. Use ColorMap.Builder.override(Color, float) to add a new point to override the color at.

Method Details

minValue

public float minValue()

Gets the smallest value a color is defined for

Returns:

The minimum value

Since:

0.14.15.6

maxValue

public float maxValue()

Gets the largest value a color is defined for

Returns:

The maximum value

Since:

0.14.15.6

recomputeLookups

public void recomputeLookups(float resolution)

Recomputes the lookup table with the given resolution.

Parameters:

resolution - The new resolution

Since:

0.14.16.1

get

public Color get(float val)

Retrieves the color value using the closest value from the lookup table. If you need the accurate value, use getAccurate(float) instead

Parameters:

val - The value to get a color for

Returns:

The approximate color for this value

Since:

0.14.16.1

• getAccurate(float)

getAccurate

public Color getAccurate(float val)

Gets the Color for the specific value.
This method is SLOWER and oftentimes the same as get(float). Use that instead if you only need the approximate value

Parameters:

val - The value to get the Color of

Returns:

The Color for the given value

Since:

0.14.15.6

• get(float)

lerp

public static Color lerp(float delta,
 Color c1,
 Color c2)

Lerps between two colors

Parameters:

delta - The t-value from 0 to 1

c1 - The first Color

c2 - The second Color

Returns:

A Color lerped between c1 and c2

Since:

0.14.15.6
