| 36 | * @Description: |
| 37 | * A CID_Parser is an object used to parse a Type 1 fonts very |
| 38 | * quickly. |
| 39 | * |
| 40 | * @Fields: |
| 41 | * root :: |
| 42 | * The root PS_ParserRec fields. |
| 43 | * |
| 44 | * stream :: |
| 45 | * The current input stream. |
| 46 | * |
| 47 | * postscript :: |
| 48 | * A pointer to the data to be parsed. |
| 49 | * |
| 50 | * postscript_len :: |
| 51 | * The length of the data to be parsed. |
| 52 | * |
| 53 | * data_offset :: |
| 54 | * The start position of the binary data (i.e., the |
| 55 | * end of the data to be parsed. |
| 56 | * |
| 57 | * binary_length :: |
| 58 | * The length of the data after the `StartData' |
| 59 | * command if the data format is hexadecimal. |
| 60 | * |
| 61 | * cid :: |
| 62 | * A structure which holds the information about |
| 63 | * the current font. |
| 64 | * |
| 65 | * num_dict :: |
| 66 | * The number of font dictionaries. |
