Direct Known Subclasses:

PDCIEDictionaryBasedColorSpace, PDICCBased

public abstract class PDCIEBasedColorSpace
extends PDColorSpace

CIE-based colour spaces specify colours in a way that is independent of the characteristics of any particular output device. They are based on an international standard for colour specification created by the Commission Internationale de l'Éclairage (CIE).

Method Details

toRGBImage

public BufferedImage toRGBImage(WritableRaster raster)
                         throws IOException

Description copied from class: PDColorSpace

Returns the (A)RGB equivalent of the given raster.

Specified by:

toRGBImage in class PDColorSpace

Parameters:

raster - the source raster

Returns:

an (A)RGB buffered image

Throws:

IOException - if the color conversion fails

toRawImage

public BufferedImage toRawImage(WritableRaster raster)
                         throws IOException

Description copied from class: PDColorSpace

Returns the image in this colorspace or null. No conversion is performed.

For special colorspaces like PDSeparation the image is returned in the gray colorspace. For undefined colorspaces like DeviceCMYK/DeviceRGB and DeviceGray null is returned.

You can always fallback to PDColorSpace.toRGBImage(WritableRaster) if this returns null.

Specified by:

toRawImage in class PDColorSpace

Parameters:

raster - the source raster

Returns:

an buffered image in this colorspace. Or null if it is not possible to extract that image with the original colorspace without conversion.

Throws:

IOException

toString

public String toString()

Overrides:

toString in class Object
