checkCompatibilityWithColorSpace

public boolean checkCompatibilityWithColorSpace(PdfColorSpace alternateSpace)

Description copied from class: AbstractPdfFunction

Chacks wether the output of the function matches in components with the passed by color space.

Specified by:

checkCompatibilityWithColorSpace in interface IPdfFunction

Overrides:

checkCompatibilityWithColorSpace in class AbstractPdfFunction<PdfStream>

Parameters:

alternateSpace - The color space to verify against

Returns:

True when compatible

setDomain

public void setDomain(double[] domain)

Description copied from class: AbstractPdfFunction

The valid input domain, input will be clipped to this domain contains a min max pair per input component.

(see ISO-320001 Table 38)

Specified by:

setDomain in interface IPdfFunction

Overrides:

setDomain in class AbstractPdfFunction<PdfStream>

Parameters:

domain - the new set of limits

setRange

public void setRange(double[] range)

Description copied from class: AbstractPdfFunction

the valid output range, output will be clipped to this range contains a min max pair per output component.

(see ISO-320001 Table 38)

Specified by:

setRange in interface IPdfFunction

Overrides:

setRange in class AbstractPdfFunction<PdfStream>

Parameters:

range - the new set of limts

calculate

public double[] calculate(double[] input)

Description copied from interface: IPdfFunction

Calculates one set of input components to one set of output components.

Parameters:

input - The input values size must contain IPdfFunction.getInputSize() items

Returns:

an array the size of IPdfFunction.getOutputSize() items containing the result

isWrappedObjectMustBeIndirect

protected boolean isWrappedObjectMustBeIndirect()

Description copied from class: PdfObjectWrapper

Defines if the object behind this wrapper must be an indirect object in the resultant document.

If this method returns true it doesn't necessarily mean that object must be in the indirect state at any moment, but rather defines that when the object will be written to the document it will be transformed into indirect object if it's not indirect yet.

Return value of this method shouldn't depend on any logic, it should return always true or false.

Specified by:

isWrappedObjectMustBeIndirect in class PdfObjectWrapper<PdfStream>

Returns:

true if in the resultant document the object behind the wrapper must be indirect, otherwise false.
