Detailed Description

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

Constructor & Destructor Documentation

PoDoFo::PdfEncodingDifference::PdfEncodingDifference ( )

Create a PdfEncodingDifference object.

PoDoFo::PdfEncodingDifference::PdfEncodingDifference ( const PdfEncodingDifference rhs)

Copy a PdfEncodingDifference object.

Member Function Documentation

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

Add a difference to the object.

Parameters
nCodeunicode code point of the difference (0 to 255 are legal values)
unicodeValueactual 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 PoDoFo::PdfEncodingDifference::AddDifference ( int  nCode,
pdf_utf16be  unicodeValue,
const PdfName rName,
bool  bExplicitNames = false 
)

Add a difference to the object.

Parameters
nCodeunicode code point of the difference (0 to 255 are legal values)
unicodeValueactual unicode value for nCode; can be 0
rNamename of the different code point or .notdef if none
bExplicitKeysif true, the unicode value is set to nCode as rName is meaningless (Type3 fonts)
bool PoDoFo::PdfEncodingDifference::Contains ( int  nCode,
PdfName rName,
pdf_utf16be &  rValue 
) const

Tests if the specified code is part of the differences.

Parameters
nCodetest if the given code is part of the differences
rNamewrite the associated name into this object if the code is part of the difference
rValuewrite the associated unicode value of the name to this value
Returns
true if the code is part of the difference
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
const PdfEncodingDifference & PoDoFo::PdfEncodingDifference::operator= ( const PdfEncodingDifference rhs)

Copy a PdfEncodingDifference object.

void PoDoFo::PdfEncodingDifference::ToArray ( PdfArray rArray)

Convert the PdfEncodingDifference to an array

Parameters
rArraywrite to this array
