fromCIEXYZ	back to summary
public float[] fromCIEXYZ(float[] xyzvalue) Implements abstract java.awt.color.ColorSpace.fromCIEXYZ. Doc from java.awt.color.ColorSpace.fromCIEXYZ. Transforms a color value assumed to be in the `CS_CIEXYZ` conversion color space into this `ColorSpace`. This method transforms color values using relative colorimetry, as defined by the International Color Consortium standard. This means that the XYZ argument values taken by this method are represented relative to the D50 white point of the `CS_CIEXYZ` color space. This representation is useful in a two-step color conversion process in which colors are transformed from an input color space to `CS_CIEXYZ` and then to an output color space. The color values returned by this method are not those that would produce the XYZ value passed to the method when measured by a colorimeter. If you have XYZ values corresponding to measurements made using current CIE recommended practices, they must be converted to D50 relative values before being passed to this method. See the `fromCIEXYZ` method of `ICC_ColorSpace` for further information. Parameters xyzvalue:float[] a float array with length of at least 3 Returns:float[] a float array with length equal to the number of components in this `ColorSpace`

fromRGB	back to summary
public float[] fromRGB(float[] rgbvalue) Implements abstract java.awt.color.ColorSpace.fromRGB. Doc from java.awt.color.ColorSpace.fromRGB. Transforms a color value assumed to be in the default `CS_sRGB` color space into this `ColorSpace`. This method transforms color values using algorithms designed to produce the best perceptual match between input and output colors. In order to do colorimetric conversion of color values, you should use the `toCIEXYZ` method of the `CS_sRGB` color space to first convert from the input color space to the `CS_CIEXYZ` color space, and then use the `fromCIEXYZ` method of this color space to convert from `CS_CIEXYZ` to the output color space. See `toCIEXYZ` and `fromCIEXYZ` for further information. Parameters rgbvalue:float[] a float array with length of at least 3 Returns:float[] a float array with length equal to the number of components in this `ColorSpace`

public float[] toCIEXYZ(float[] colorvalue) Implements abstract java.awt.color.ColorSpace.toCIEXYZ. Doc from java.awt.color.ColorSpace.toCIEXYZ. Transforms a color value assumed to be in this `ColorSpace` into the `CS_CIEXYZ` conversion color space. This method transforms color values using relative colorimetry, as defined by the International Color Consortium standard. This means that the XYZ values returned by this method are represented relative to the D50 white point of the `CS_CIEXYZ` color space. This representation is useful in a two-step color conversion process in which colors are transformed from an input color space to `CS_CIEXYZ` and then to an output color space. This representation is not the same as the XYZ values that would be measured from the given color value by a colorimeter. A further transformation is necessary to compute the XYZ values that would be measured using current CIE recommended practices. See the `toCIEXYZ` method of `ICC_ColorSpace` for further information.
