Method

intRGBToInt(float[] rgb)
RGB To Int 
byte[] argb = { (byte) 0xFF, (byte) (rgb[0] * 0xFF), (byte) (rgb[1] * 0xFF), (byte) (rgb[2] * 0xFF) };
return (argb[0] << 24) + ((argb[1] & 0xFF) << 16) + ((argb[2] & 0xFF) << 8) + (argb[3] & 0xFF);
intRGBtoInt(int r, int g, int b)
Converts RGB values to an RGB integer value. 
return (256 * 256 * r + 256 * g + b);
intRGBtoInt(int red, int green, int blue)
RG Bto Int 
return 255 << 24 | red << 16 | +green << 8 | blue;
intRGBtoInt(String rgb)
RG Bto Int 
int r = Integer.parseInt(getR(rgb), 16);
int g = Integer.parseInt(getG(rgb), 16);
int b = Integer.parseInt(getB(rgb), 16);
int clr = r;
clr = clr << 8 | g;
clr = clr << 8 | b;
return clr;
intRGBToInteger(int red, int green, int blue)
Converts representation of color in RGB model in triplet (r, g, b) to single number in hexadecimal system. 
return 0x00000000 | (red << 16) | (green << 8) | blue;
shortrgbToShort(int rgb)
Converts a 24 bit RGB value to a 15 bit RGB value. 
return (short) (((rgb & 0xf8) >> 3) | ((rgb & 0xf800) >> 6) | ((rgb & 0xf80000) >> 9));
StringrgbToString(float r, float g, float b)
rgb To String 
String rs = Integer.toHexString((int) (r * 256));
String gs = Integer.toHexString((int) (g * 256));
String bs = Integer.toHexString((int) (b * 256));
return "#" + rs + gs + bs;
StringrgbToText(int red, int green, int blue)
Converts a color's RGB presentation to a textual hexadecimal representation. 
return String.format("#%02x%02x%02x", red, green, blue);
