29 /** This is a color name lookup targeted to be used by the accessibility
30 <type>DescriptionGenerator</type> class. It encapsulates a
31 <type>com.sun.star.drawing.ColorTable</type> and provides an inverse look
32 up of color names for given numerical color descriptions (the RGB values
33 encoded as an integer).
35 <p>The implementation uses as singleton so that the
36 <type>com.sun.star.drawing.ColorTable</type> object needs to be created
37 only once. That singleton instance for now lives until the application
38 terminates. However, the color table from which it takes its values may
39 change during this time. Reacting to these changes remains a task for the
40 future.</p>
42 @param nColor
43 This integer is the sum of the 8 Bit red value shifted left 16 Bits, the
44 green value shifted left 8 Bits, and the unshifted blue value.
46 @return
47 The returned string is either the color name of the specified color or,
48 when no name exists, a string of the form "#RRGGBB" with two hexadecimal
49 digits for each color component.
