All Known Implementing Classes:

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.

Method Detail

toCmyk

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

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

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

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.
