Barcode-Lib4J requires Java 9+

Package de.vwsoft.barcodelib4j.image

Java Class «CompoundColor» – Stores CMYK and RGB independently

java.lang.Object

java.awt.Color

de.vwsoft.barcodelib4j.image.CompoundColor

All Implemented Interfaces:

Paint, Transparency, Serializable

public class CompoundColor
extends Color

Stores a color independently in the RGB and CMYK color models.

There are two types of constructors available:

• The first type accepts colors in both RGB and CMYK color models as parameters and stores them separately.
• The second type accepts either an RGB or a CMYK color as a parameter and converts the other color using a simple algorithm based on the provided color.

The second type of constructor is likely the one you will use most often, as you typically work with just one of the two color models.

Note: Since the CMYK color model does not support transparency, any transparency information passed as a parameter for RGB colors is ignored.

Field Details

CC_BLACK

public static final CompoundColor CC_BLACK

Constant representing the color black in both RGB and CMYK color models.

CC_WHITE

public static final CompoundColor CC_WHITE

Constant representing the color white in both RGB and CMYK color models.

Constructor Details

CompoundColor

public CompoundColor(int r,
 int g,
 int b,
 int c,
 int m,
 int y,
 int k)

Constructs a new instance with the specified RGB and CMYK values. No conversion between RGB and CMYK color models takes place.

Parameters:

r - the red component of the RGB color (0-255)

g - the green component of the RGB color (0-255)

b - the blue component of the RGB color (0-255)

c - the cyan component of the CMYK color (0-100)

m - the magenta component of the CMYK color (0-100)

y - the yellow component of the CMYK color (0-100)

k - the key (black) component of the CMYK color (0-100)

CompoundColor

public CompoundColor(int rgb,
 int cmyk)

Constructs a new instance with the specified RGB and CMYK values. No conversion between RGB and CMYK color models takes place.

Parameters:

rgb - the RGB value of the color

cmyk - the CMYK value of the color

CompoundColor

public CompoundColor(long rgbAndCmyk)

Constructs a new instance with the specified RGB and CMYK values. No conversion between RGB and CMYK color models takes place. The RGB value must occupy the higher 32 bits of the long parameter, while the CMYK value must occupy the lower 32 bits.

Parameters:

rgbAndCmyk - a long value representing both the RGB and CMYK colors

• getRGBandCMYK()

CompoundColor

public CompoundColor(int r,
 int g,
 int b)

Constructs a new instance with the specified RGB values. The CMYK values are calculated internally from the given RGB values, striving for the closest approximation.

Parameters:

r - the red component of the RGB color (0-255)

g - the green component of the RGB color (0-255)

b - the blue component of the RGB color (0-255)

CompoundColor

public CompoundColor(int c,
 int m,
 int y,
 int k)

Constructs a new instance with the specified CMYK values. The RGB values are calculated internally from the given CMYK values, striving for the closest approximation.

Parameters:

c - the cyan component of the CMYK color (0-100)

m - the magenta component of the CMYK color (0-100)

y - the yellow component of the CMYK color (0-100)

k - the key (black) component of the CMYK color (0-100)

CompoundColor

public CompoundColor(Color rgbColor)

Constructs a new instance with the specified java.awt.Color. The CMYK values are calculated internally from the given RGB values, striving for the closest approximation.

Parameters:

rgbColor - the java.awt.Color object from which to construct the CompoundColor

CompoundColor

public CompoundColor(int value,
 boolean isRGB)

Constructs a new instance with the specified value. If isRGB is true, the integer value represents an RGB color, otherwise, it represents a CMYK color. The CMYK values are calculated internally if the integer value represents an RGB color, or the RGB values are calculated internally if the integer value represents a CMYK color, striving for the closest approximation.

Parameters:

value - the integer value representing either an RGB or CMYK color

isRGB - true if the value represents an RGB color, false if it represents a CMYK color
