* @Description:
|
|
* A PS_ParserRec is an object used to parse a Type 1 fonts very
|
|
* quickly.
|
|
*
|
|
* @Fields:
|
|
* root ::
|
|
* The root parser.
|
|
*
|
|
* stream ::
|
|
* The current input stream.
|
|
*
|
|
* base_dict ::
|
|
* A pointer to the top-level dictionary.
|
|
*
|
|
* base_len ::
|
|
* The length in bytes of the top dictionary.
|
|
*
|
|
* private_dict ::
|
|
* A pointer to the private dictionary.
|
|
*
|
|
* private_len ::
|
|
* The length in bytes of the private dictionary.
|
|
*
|
|
* in_pfb ::
|
|
* A boolean. Indicates that we are handling a PFB
|
|
* file.
|
|
*
|
|
* in_memory ::
|
|
* A boolean. Indicates a memory-based stream.
|
|
*
|
|
* single_block ::
|
|
* A boolean. Indicates that the private dictionary
|
|
* is stored in lieu of the base dictionary.
