result = cgCOLOR24(color)
The purpose of this function is to convert a RGB color triple
into the equivalent 24-bit long integer. The 24-bit integer
can be decomposed into the appropriate color by interpreting
the lowest 8 bits as red, the middle 8 bits as green, and the
highest 8 bits as blue. This routine was written to be used with
device-independent color programs like cgColor.
Return value
A 24-bit long integer that can be decomposed into a color triple value.
Parameters
- color in required
A three-element column or row array representing a color triple. Or an N-by-three element array of color triples. The values of the elements must be between 0 and 255.
Examples
To convert the color triple for the color YELLOW, (255, 255, 0), to the hexadecimal value '00FFFF'x or the decimal number 65535, type:
color = COLOR24([255, 255, 0])
