Constructor Details

PDCIEDictionaryBasedColorSpace

protected PDCIEDictionaryBasedColorSpace(COSName cosName)

PDCIEDictionaryBasedColorSpace

protected PDCIEDictionaryBasedColorSpace(COSArray rgb)

Creates a new CalRGB color space using the given COS array.

Parameters:

rgb - the cos array which represents this color space

Method Details

convXYZtoRGB

protected float[] convXYZtoRGB(float x,
 float y,
 float z)

getWhitepoint

public final PDTristimulus getWhitepoint()

This will return the whitepoint tristimulus. As this is a required field this will never return null. A default of 1,1,1 will be returned if the pdf does not have any values yet.

Returns:

the whitepoint tristimulus

getBlackPoint

public final PDTristimulus getBlackPoint()

This will return the BlackPoint tristimulus. This is an optional field but has defaults so this will never return null. A default of 0,0,0 will be returned if the pdf does not have any values yet.

Returns:

the blackpoint tristimulus

setWhitePoint

public void setWhitePoint(PDTristimulus whitepoint)

This will set the whitepoint tristimulus. As this is a required field this null should not be passed into this function.

Parameters:

whitepoint - the whitepoint tristimulus

setBlackPoint

public void setBlackPoint(PDTristimulus blackpoint)

This will set the BlackPoint tristimulus.

Parameters:

blackpoint - the BlackPoint tristimulus
