public class HSBPixelFormat

extends PixelFormat

a Format object for reading in an HSB color and opacity.

This Format supports the following formats for describing a color and its opacity:

• 4 space-delimited floating numbers between 0 and 1 indicating HSBA, e.g. 0.7858 1.0000 0.4747 1.0
• 3 space-delimited floating numbers between 0 and 1 indicating HSB, e.g. 0.7858 1.0000 0.4747; opacity is assumed to be 1.0 if not given.

The Object handed to format as well as the result of parsing is a 4-element byte array containing the red, green, blue, and alpha values.
