Class CMapAwareDocumentFont

public class CMapAwareDocumentFont extends DocumentFont

Implementation of DocumentFont used while parsing PDF streams.

Since: 2.1.4

Field Summary
CMap	cmap CMap instance.
PdfDictionary	fontDic The font dictionary.
int	spaceWidth the width of a space for this font, in normalized 1000 point units

Constructor Summary
	CMapAwareDocumentFont(PRIndirectReference refFont) Creates an instance of a CMapAwareFont based on an indirect reference to a font.

Method Summary
int	computeAverageWidth() For all widths of all glyphs, compute the average width in normalized 1000 point units.
String	encode(byte[] bytes, int offset, int len) Encodes bytes to a String.
int	getWidth(int char1)
void	processToUni() Does some processing if the font dictionary indicates that the font is in unicode.

Field Detail

fontDic

private PdfDictionary fontDic

The font dictionary.

spaceWidth

private int spaceWidth

the width of a space for this font, in normalized 1000 point units

Constructor Detail

CMapAwareDocumentFont

public CMapAwareDocumentFont(PRIndirectReference refFont)

Creates an instance of a CMapAwareFont based on an indirect reference to a font.

Parameters: refFont the indirect reference to a font

For all widths of all glyphs, compute the average width in normalized 1000 point units. This is used to give some meaningful width in cases where we need an average font width (such as if the width of a space isn't specified by a given font)

Returns: the average width of all non-zero width glyphs in the font

encode

public String encode(byte[] bytes, int offset, int len)

Encodes bytes to a String.

Parameters: bytes the bytes from a stream offset an offset len a length

Returns: a String encoded taking into account if the bytes are in unicode or not.

getWidth

public int getWidth(int char1)

Since: 2.1.5 Override to allow special handling for fonts that don't specify width of space character

processToUni

private void processToUni()

Does some processing if the font dictionary indicates that the font is in unicode.
