,PDICCBased
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).

toRGBImage
Description copied from class:PDColorSpace
Returns the (A)RGB equivalent of the given raster.- Specified by:
toRGBImage
in classPDColorSpace
- Parameters:
raster
- the source raster- Returns:
- an (A)RGB buffered image
- Throws:
IOException
- if the color conversion fails
-
toRawImage
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 toPDColorSpace.toRGBImage(WritableRaster)
if this returns null.- Specified by:
toRawImage
in classPDColorSpace
- 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
