Purpose

---

    Translates RGB triplets into colour indices for 24-bit decomposed mode.

Calling Sequence

---

    Result = RGBINDEX(R, G, B)

Inputs

---

    R: A byte or array of bytes of red values.
    G: A byte or array of bytes of green values.
    B: A byte or array of bytes of blue values.

Outputs

---

    Returns the colour index or indices for 24-bit decomposed mode
    (DEVICE, DECOMPOSED=1) corresponding to the R,G,B triplets.

Example

---

    r = [0,128,255]
    g = [128,128,128]
    b = [255,128,0]
    colourarray = RGBINDEX(r, g, b)
