extractExtGStateDictionaries

public List<COSDictionary> extractExtGStateDictionaries(PreflightContext context,
                                                        COSDictionary egsEntry)
                                                 throws ValidationException

Create a list of ExtGState dictionaries using the given Resource dictionary and the COSDocument.

Parameters:

context - the context which contains the Resource dictionary.

egsEntry - a resource COSDictionary.

Returns:

the list of ExtGState dictionaries.
