java.lang.Object org.eclipse.swt.graphics.RGB
public final class RGB
Instances of this class are descriptions of colors in terms of the primary additive color model (red, green and blue). A color may be described in terms of the relative intensities of these three primary colors. The brightness of each color is specified by a value in the range 0 to 255, where 0 indicates no color (blackness) and 255 indicates maximum intensity.
The hashCode() method in this class uses the values of the public fields to compute the hash value. When storing instances of the class in hashed collections, do not modify these fields after the object has been inserted.
Application code does not need to explicitly release the resources
managed by each instance when those instances are no longer required, and
thus no dispose()
method is provided.
