Increases/decreases lightness of the given color by the specified
difference. |
static Color |
convertHSLtoRGB(float h,
float s,
float l)
Converts the components of a color, as specified by the HSL model, to an equivalent set of values for the default RGB
model.
|
static float[] |
convertRGBtoHSL(int r,
int g,
int b)
Converts the components of a color, as specified by the default RGB model, to an equivalent set of values for hue,
saturation, and lightness that are the three components of the HSL model.
|
static Color |
overwriteAlpha(Color c,
float alpha)
Overwrites alpha value for given color.

r - the red component of the colorg - the green component of the colorb - the blue component of the colorpublic static Color convertHSLtoRGB(float h, float s, float l)
The saturation and lightness components should be floating-point values between zero and one
(numbers in the range 0.0-1.0). The hue component can be any floating-point number. The floor of this number
is subtracted from it to create a fraction between 0 and 1. This fractional number is then multiplied by 360 to produce
the hue angle in the HSB color model.
h - the hue component of the colors - the saturation of the colorl - the lightness of the colorpublic static Color adjustBrightness(Color c, float difference)
difference.
The difference values in the range (-1.0, 1.0): 1.0 - the brightest value; -1.0 - the dimmest value.

difference.
The difference values in the range (-1.0, 1.0): 1.0 - the lightest value; -1.0 - on the contrary.
