public PDDeviceN() 
{
        array = new COSArray();
        array.add( COSName.getPDFName( NAME ) );
        array.add( COSName.getPDFName( "" ) );
}

Constructor.

 public PDDeviceN(COSArray separation) 
{
        array = separation;
}

Constructor.

Parameters:

separation - The array containing all separation information.

 public ColorModel createColorModel(int bpc) throws IOException 
{
        throw new IOException( "Not implemented" );
}

Create a Java color model for this colorspace.

 protected ColorSpace createColorSpace() throws IOException 
{
        throw new IOException( "Not implemented" );
}

Create a Java colorspace for this colorspace.

 public PDColorSpace getAlternateColorSpace() throws IOException 
{
        COSBase alternate = array.getObject( 2 );
        return PDColorSpaceFactory.createColorSpace( alternate );
}

This will get the alternate color space for this separation.

 public PDDeviceNAttributes getAttributes() 
{
        PDDeviceNAttributes retval = null;
        if( array.size() < 5)
        {
            retval = new PDDeviceNAttributes();
            setAttributes( retval );
        }
        return retval;
}

This will get the attributes that are associated with the deviceN color space.

 public List getColorantNames() 
{
        COSArray names = (COSArray)array.getObject( 1 );
        return COSArrayList.convertCOSNameCOSArrayToList( names );
}

This will get the colorant names. A list of string objects.

 public String getName() 
{
        return NAME;
}

This will return the name of the color space. For a PDSeparation object this will always return "Separation"

 public int getNumberOfComponents() throws IOException 
{
        return getColorantNames().size();
}

This will get the number of components that this color space is made up of.

 public PDFunction getTintTransform() throws IOException 
{
        return  PDFunction.create( array.getObject( 3 ) );
}

This will get the tint transform function.

 public  void setAlternateColorSpace(PDColorSpace cs) 
{
        COSBase space = null;
        if( cs != null )
        {
            space = cs.getCOSObject();
        }
        array.set( 2, space );
}

This will set the alternate color space.

 public  void setAttributes(PDDeviceNAttributes attributes) 
{
        if( attributes == null )
        {
            array.remove( 4 );
        }
        else
        {
            //make sure array is large enough
            while( array.size() <  5 )
            {
                array.add( COSNull.NULL );
            }
            array.set( 4, attributes.getCOSDictionary() );
        }
}

This will set the color space attributes. If null is passed in then all attribute will be removed.

 public  void setColorantNames(List names) 
{
        COSArray namesArray = COSArrayList.convertStringListToCOSNameCOSArray( names );
        array.set( 1, namesArray );
}

This will set the list of colorants.

 public  void setTintTransform(PDFunction tint) 
{
        array.set( 3, tint );
}

This will set the tint transform function.
