public class DeviceNColorSpace extends ColorSpace
This class represents a "Device N" ColorSpace, which is a ColorSpace with
N individual inks - the SpotColorSpace
class is a special
case of this class where there is only one ink. This class has no public
constructor, as it is not normally something that would be created by
a user of this API. The class itself is public primarily for preflighting:
an instance of this ColorSpace may be passed in to OutputProfiler.ColorAction.changeColor(org.faceless.pdf2.OutputProfiler, java.awt.color.ColorSpace, float[], float[], boolean, int)
.
Note that unlike "process" ColorSpaces, colors in this space can be converted from
this space to RGB or XYZ, but not the other way - these spaces are not constructed
in a way that makes it easy to map an RGB value to a Color in this class (nor would
it be useful). Consequently the fromRGB(float[])
and fromCIEXYZ(float[])
methods
throw an UnsupportedOperationException

fromCIEXYZ(float[] xyz)
Theoretically transforms a color value assumed to be in the XYZ ColorSpace into values
in this ColorSpace.

fromRGB(float[] rgb)
Theoretically transforms a color value assumed to be in the sRGB ColorSpace into values
in this ColorSpace.

getFallbackColorSpace()
Get the ColorSpace which defines the "fallback" color,
which must be a process ColorSpace (i.e.

getName(int i)
Returns the name of the specified component
|

getNumComponents()
Returns the number of components of this ColorSpace.

remap(ColorSpace newfallback)
Attempt to convert this DeviceNColorSpace to an equavalent one, but with a different
fallback ColorSpace.

float[] |
toCIEXYZ(float[] colorvalue)
Transforms a color value assumed to be in this ColorSpace into the CIEXYZ values.
|
float[] |
toFallback(float[] input)
Convert the color components in this color to the components
in the
fallback ColorSpace |

toRGB(float[] colorvalue)
Transforms a color value assumed to be in this ColorSpace into a value in the
default CS_sRGB color space.

Transforms a color value assumed to be in this ColorSpace into a value in the
default CS_sRGB color space. Calls toRGB
on the fallback colorspace.

Theoretically transforms a color value assumed to be in the sRGB ColorSpace into values
in this ColorSpace. In practice this can't easily be done and isn't useful, so throws
