Interface ColorConverter

All Known Implementing Classes:

BasicColorConverter, NoColorConverter

public interface ColorConverter

This interface describes the possibilities of a color conversion.

Consider the situation that a color is resent which is not in the needed color model; For instance a CMYK color is given and a RGB color is needed. In this situation a color converter can be used to translate between the given color and the needed color.

A color converter can refuse to translate a given color. In this case the conversion method simply returns null. This enables us to define color converters which signal that a translation is not desirable – e.g. because the result might be poor.

toCmyk

public CmykColor toCmyk(Color color)

Convert an arbitrary color to the CMYK model. If an conversion is not supported then null is returned.

Parameters:

color - the color to convert

Returns:

the corresponding color in the CMYK model or null if a conversion is not supported.

toGrayscale

public GrayscaleColor toGrayscale(Color color)

Convert an arbitrary color to the RGB model. If an conversion is not supported then null is returned.

Parameters:

color - the color to convert

Returns:

the corresponding color in the RGB model or null if a conversion is not supported.

toHsv

public HsvColor toHsv(Color color)

Convert an arbitrary color to the HSV model. If an conversion is not supported then null is returned.

Parameters:

color - the color to convert

Returns:

the corresponding color in the HSV model or null if a conversion is not supported.

toRgb

public RgbColor toRgb(Color color)

Convert an arbitrary color to the RGB model. If an conversion is not supported then null is returned.

Parameters:

color - the color to convert

Returns:

the corresponding color in the RGB model or null if a conversion is not supported.
