Member Function Documentation

AddDifference() [1/2]

void PoDoFo::PdfEncodingDifference::AddDifference	(	int	nCode,
		pdf_utf16be	unicodeValue )

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

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

AddDifference() [2/2]

void PoDoFo::PdfEncodingDifference::AddDifference	(	int	nCode,
		pdf_utf16be	unicodeValue,
		const PdfName &	rName,
		bool	bExplicitNames = false )

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
rName	name of the different code point or .notdef if none
bExplicitKeys	if true, the unicode value is set to nCode as rName is meaningless (Type3 fonts)

Contains()

bool PoDoFo::PdfEncodingDifference::Contains	(	int	nCode,
		PdfName &	rName,
		pdf_utf16be &	rValue ) const

Tests if the specified code is part of the differences.

Parameters

nCode	test if the given code is part of the differences
rName	write the associated name into this object if the code is part of the difference
rValue	write the associated unicode value of the name to this value

Returns

true if the code is part of the difference

GetCount()

size_t PoDoFo::PdfEncodingDifference::GetCount ( ) const

inline

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.

Returns

the number of differences in this object

operator=()

const PdfEncodingDifference & PoDoFo::PdfEncodingDifference::operator=

(

const PdfEncodingDifference &

rhs

)

Copy a PdfEncodingDifference object.

ToArray()

void PoDoFo::PdfEncodingDifference::ToArray

(

PdfArray &

rArray

)

Convert the PdfEncodingDifference to an array

Parameters

rArray

write to this array
