Description

The list of methods to do Color Brighten are organized into topic(s).

Method

StringbrighterColor(String hexValue)
brighter Color 
return brighterColor(hexValue, 0.1);
Colorbrightness(Color c, float scale)
Adjusts the brightness of the given color. 
int r = c.getRed();
int g = c.getGreen();
int b = c.getBlue();
if (r == 0 && g == 0 && b == 0 && scale > 0) {
    r = g = b = Math.min(255, (int) (255 * scale));
} else {
    r = Math.max(0, (int) (r * scale));
    g = Math.max(0, (int) (g * scale));
...
floatbrightness(java.awt.Color c)
brightness 
if (c == null)
    return 0;
final int r = c.getRed();
final int g = c.getGreen();
final int b = c.getBlue();
int max = (r > g) ? r : g;
if (b > max)
    max = b;
...
BufferedImagebrightnessToAlpha(Image image, float alpha)
Takes the image brightness and turns it into an alpha-channel. 
return brightnessToAlpha(image, (int) (255f * alpha));
ColorchangeBrightness(Color c, int percent)
Construct a Color that is a brighter or darker version of a given color. 
if (c == null) {
    return c;
int r = c.getRed();
int g = c.getGreen();
int b = c.getBlue();
float[] hsb = Color.RGBtoHSB(r, g, b, null);
float fraction = (float) percent / 100;
...
ColorchangeColorBrightness(final Color color, final double delta)
change Color Brightness 
int r = (int) Math.min(color.getRed() * delta, 255.0);
int g = (int) Math.min(color.getGreen() * delta, 255.0);
int b = (int) Math.min(color.getBlue() * delta, 255.0);
return new Color(r, g, b);
ColorderiveByBrightness(Color original, Color brightnessSource)
Derives a color based on the original color and a brightness source. 
float[] hsbvalsOrig = new float[3];
Color.RGBtoHSB(original.getRed(), original.getGreen(), original.getBlue(), hsbvalsOrig);
float[] hsbvalsBrightnessSrc = new float[3];
Color.RGBtoHSB(brightnessSource.getRed(), brightnessSource.getGreen(), brightnessSource.getBlue(),
        hsbvalsBrightnessSrc);
return new Color(
        Color.HSBtoRGB(hsbvalsOrig[0], hsbvalsOrig[1], (hsbvalsBrightnessSrc[2] + hsbvalsOrig[2]) / 2.0f));
ColorderiveColorHSB(Color base, float hue, float saturation, float brightness)
derive Color HSB 
float hsb[] = Color.RGBtoHSB(base.getRed(), base.getGreen(), base.getBlue(), null);
hsb[0] += hue;
hsb[1] += saturation;
hsb[2] += brightness;
return Color.getHSBColor(hsb[0] < 0 ? 0 : (hsb[0] > 1 ? 1 : hsb[0]),
        hsb[1] < 0 ? 0 : (hsb[1] > 1 ? 1 : hsb[1]), hsb[2] < 0 ? 0 : (hsb[2] > 1 ? 1 : hsb[2]));
intgetBrightness(Color c)
Calculates the brightness of a color. 
double b = c.getRed() * c.getRed() * .241D + c.getGreen() * c.getGreen() * .691D
        + c.getBlue() * c.getBlue() * .068D;
return (int) Math.sqrt(b);
intgetBrightness(Color c)
get Brightness 
final int r = c.getRed();
final int g = c.getGreen();
final int b = c.getBlue();
return (int) Math.sqrt(r * r * .241 + g * g * .691 + b * b * .068);
