buildObjects

public byte[][] buildObjects(int firstObjectId,
 boolean compress)
                      throws IOException

Builds the five PDF objects of this font. The objects use consecutive ids starting at firstObjectId in this order: Type0 font, CIDFontType2 font, font descriptor, FontFile2 stream, ToUnicode stream.

Parameters:

firstObjectId - the id of the first object

compress - whether to Flate-compress the font file and the ToUnicode stream

Returns:

one complete "N 0 obj ... endobj" byte array per object

Throws:

IOException - Signals that an I/O exception has occurred.
