Detailed Description

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

Member Function Documentation

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

Add a difference to the encoding.

The added name is determined by the "Adobe Glyph List for New Fonts" https://github.com/adobe-type-tools/agl-aglfn/blob/master/aglfn.txt

Parameters

code	code unit of the difference (0 to 255 are legal values)
codePoint	actual unicode code point

void PdfDifferenceMap::AddDifference	(	unsigned char	code,
		const codepointview &	codePoints
	)

Add a difference to the encoding.

The added name is determined by the "Adobe Glyph List for New Fonts" https://github.com/adobe-type-tools/agl-aglfn/blob/master/aglfn.txt

Parameters

code	code unit of the difference (0 to 255 are legal values)
codePoints	a span of unicode code points

unsigned PdfDifferenceMap::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 PdfDifferenceMap::ToArray ( PdfArray & arr ) const

Convert the PdfEncodingDifference to an array.

Parameters

arr	write to this array

bool PdfDifferenceMap::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
codePoints	write the associated unicode values of the name to this value
