Detailed Description

A helper class for PdfDifferenceEncoding that can be used to create a differences array.

Member Function Documentation

void PdfDifferenceList::AddDifference	(	unsigned char	code,
		char32_t	codePoint
	)

Add a difference to the object.

Parameters

nCode	unicode code point of the difference (0 to 255 are legal values)
unicodeValue	actual unicode value for nCode; can be 0

See also: AddDifference if you know the name of the code point use the overload below which is faster

void PdfDifferenceList::AddDifference	(	unsigned char	code,
		const PdfName &	name,
		bool	explicitNames = `false`
	)

Add a difference to the object.

Parameters

name	unicode code point of the difference (0 to 255 are legal values)
name	name of the different code point or .notdef if none
explicitNames	if true, the unicode value is set to nCode as name is meaningless (Type3 fonts)

size_t PdfDifferenceList::GetCount ( ) const

Get the number of differences in this object.

If the user added .notdef as a difference it is counted, even it is no real difference in the final encoding.

void PdfDifferenceList::ToArray ( PdfArray & arr ) const

Convert the PdfEncodingDifference to an array.

Parameters

arr	write to this array

bool PdfDifferenceList::TryGetMappedName	(	unsigned char	code,
		const PdfName *&	name
	)		const

Get the mapped code point from a char code.

Parameters

code	test if the given code is part of the differences
codePoint	write the associated unicode value of the name to this value
