Method

intrgbToGray(int pixels)
rgb To Gray 
int _red = (pixels >> 16) & 0xFF;
int _green = (pixels >> 8) & 0xFF;
int _blue = (pixels) & 0xFF;
return (int) (0.3 * _red + 0.59 * _green + 0.11 * _blue);
intRgbToGray(int r, int g, int b)
Rgb To Gray 
return (int) (r * .3 + g * .59 + b * .11);
byte[]rgbToGrey(byte[] rgb)
Return a grey RGB triplet corresponding to the luminance of the incoming color RGB triplet. 
byte[] g = new byte[3];
int lum = getRGBLum(rgb);
g[0] = g[1] = g[2] = (byte) lum;
return g;
StringrgbToHex(final int r, final int g, final int b)
RGB to hex based in this 
final StringBuilder sb = new StringBuilder();
sb.append('#').append(Integer.toHexString(r)).append(Integer.toHexString(g)).append(Integer.toHexString(b));
return sb.toString();
StringrgbToHex(int r, int g, int b)
rgb To Hex 
String sr = Integer.toHexString(r);
String sg = Integer.toHexString(g);
String sb = Integer.toHexString(b);
if (sr.length() < 2)
    sr = "0" + sr;
if (sg.length() < 2)
    sg = "0" + sg;
if (sb.length() < 2)

StringRGBtoHex(int r, int g, int b)
RG Bto Hex 
String val = Integer.toHexString(r << 16 | g << 8 | b);
while (val.length() < 6)
    val = "0" + val;
return val;
StringrgbToHex(int[] rgb)
rgb To Hex 
return String.format("%02x%02x%02x", rgb[0], rgb[1], rgb[2]);
intRGBToHex(int[] rgb)
RGB To Hex 
if (rgb.length < 3)
    return -1;
return ((rgb[0] << 16) | (rgb[1] << 8) | rgb[2]);
StringrgbToHex(String color)
rgb To Hex 
String[] RGB = color.split(",");
return toHex(RGB[0]) + toHex(RGB[1]) + toHex(RGB[2]);
float[]RGBtoHSB(int r, int g, int b, float hsbvals[])
Convert from RGB to HSB color 
if (hsbvals == null) {
    hsbvals = new float[3];
int l = r <= g ? g : r;
if (b > l) {
    l = b;
int i1 = r >= g ? g : r;
