37 * @Description:
38 * A CID_Parser is an object used to parse a Type 1 fonts very
39 * quickly.
40 *
41 * @Fields:
42 * root ::
43 * The root PS_ParserRec fields.
44 *
45 * stream ::
46 * The current input stream.
47 *
48 * postscript ::
49 * A pointer to the data to be parsed.
50 *
51 * postscript_len ::
52 * The length of the data to be parsed.
53 *
54 * data_offset ::
55 * The start position of the binary data (i.e., the
56 * end of the data to be parsed.
57 *
58 * binary_length ::
59 * The length of the data after the `StartData'
60 * command if the data format is hexadecimal.
61 *
62 * cid ::
63 * A structure which holds the information about
64 * the current font.
65 *
66 * num_dict ::
67 * The number of font dictionaries.
