Constructor Detail

CFFFont

public CFFFont(RandomAccessFileOrArray inputbuffer)

Method Detail

getString

public String getString(char sid)

getCard8

char getCard8()

getCard16

char getCard16()

getOffset

int getOffset(int offSize)

seek

void seek(int offset)

getShort

short getShort()

getInt

getDictItem

protected void getDictItem()

getEntireIndexRange

protected CFFFont.RangeItem getEntireIndexRange(int indexOffset)

a utility that creates a range item for an entire index

Parameters:

indexOffset - where the index is

Returns:

a range item representing the entire index

getCID

public byte[] getCID(String fontName)

get a single CID font. The PDF architecture (1.4) supports 16-bit strings only with CID CFF fonts, not in Type-1 CFF fonts, so we convert the font to CID if it is in the Type-1 format. Two other tasks that we need to do are to select only a single font from the CFF package (this again is a PDF restriction) and to subset the CharStrings glyph description.

isCID

public boolean isCID(String fontName)

exists

public boolean exists(String fontName)

getNames

public String[] getNames()

ReadEncoding

void ReadEncoding(int nextIndexOffset)
