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.

Parameters:

fontName - name of the font

Returns:

byte array represents the CID font

isCID

             public boolean isCID()
            

isCID

             public boolean isCID
             (String fontName)
            

exists

             public boolean exists
             (String fontName)
            

getNames

             public String[] getNames()
