Method Details

getGradientFrom

public static Color[] getGradientFrom(Color a,
 Color b,
 int stepsCount)

Creates a gradient from two colors.

Parameters:

a - color A

b - color B

stepsCount - how many colors will be added between color a and b (must be non-negative)

Returns:

gradient, the first element is color a and last element is color b

getColorWithAlpha

public static Color getColorWithAlpha(Color color,
 int alpha)

Creates a new Color with the same properties as the original, but with a modified alpha value.

Parameters:

color - source color

alpha - desired alpha value

Returns:

color with desired alpha value

getGradientWithAlpha

public static LinearGradientPaint getGradientWithAlpha(LinearGradientPaint gradient,
 int alpha)

Creates a new LinearGradientPaint identical to the original, except for modified alpha values of the source colors.

Parameters:

gradient - source gradient

alpha - desired alpha value

Returns:

gradient with desired alpha value

getColorWithSaturation

public static Color getColorWithSaturation(Color color,
 float saturation)

Creates a new Color with the same properties as the original, but with a modified saturation value.

Parameters:

color - source color

saturation - desired saturation

Returns:

color with desired saturation

setGradientColors

public void setGradientColors(Color[] colors)

Set colors that will be used to create a gradient.

Parameters:

colors - gradient source colors
