Constructor Detail

CFFFont

public CFFFont(RandomAccessFileOrArray inputbuffer)
Method Detail

getString

public String getString(char sid)

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()
