Deprecated. As of TPTP 4.5.0, use the TPTP Business Intelligence and Reporting Tools (BIRT) reporting infrastructure (org.eclipse.tptp.platform.report.birt).

public class RGBA
extends java.lang.Object

Store RGBA color.
RGBA is a 32 bits colors packed in a java int, including alpha channel, all value are in range 0..255.
Alpha of 0 means fully transparent, 255 is opaque.
Red mask is 0xFF000000 (take care of sign shifting, please)
Green mask is 0x00FF0000
Blue mask is 0x0000FF00
Alpha mask if 0x000000FF
