Specified by:

checkCompatibilityWithColorSpace in interface IPdfFunction

Overrides:

checkCompatibilityWithColorSpace in class AbstractPdfFunction<PdfStream>

Parameters:

alternateSpace - The color space to verify against

Returns:

True when compatible

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
