Color information:

Ok...
I need to know how to convert from 4 rgba values ( 0 - 255 ) to one single 32 bit integer.

I already have accuired the code for converting from the integer to rgba:

Code:

---

        public static int [] int2rgba( int px )
        {
                int [] rgba = new int[4];
                rgba[3] = ( px >> 24 ) & 0xff;
                rgba[0] = ( px >> 16 ) & 0xff;
                rgba[1] = ( px >> 8 ) & 0xff;
                rgba[2] = px & 0xff;
                return rgba;
        }

---

i need to know how to change the rgba array back... anyone know?

Code:

---

public int rgba2int(int[] rgba) {
  int ret = (rgba[3] << 24) |
    (rgba[0] << 16) |
    (rgba[1] << 8) |
    rgba[2];
}

---

This will FAIL if any of the rgba members are > 255!

OK thanx!
