661 * @function:
662 * FT_Get_PS_Font_Value
663 *
664 * @description:
665 * Retrieve the value for the supplied key from a PostScript font.
666 *
667 * @input:
668 * face ::
669 * PostScript face handle.
670 *
671 * key ::
672 * An enumeration value representing the dictionary key to retrieve.
673 *
674 * idx ::
675 * For array values, this specifies the index to be returned.
676 *
677 * value ::
678 * A pointer to memory into which to write the value.
679 *
680 * valen_len ::
681 * The size, in bytes, of the memory supplied for the value.
682 *
683 * @output:
684 * value ::
685 * The value matching the above key, if it exists.
686 *
687 * @return:
688 * The amount of memory (in bytes) required to hold the requested value
689 * (if it exists, -1 otherwise).
690 *
691 * @note:
692 * The values returned are not pointers into the internal structures of
693 * the face, but are 'fresh' copies, so that the memory containing them
694 * belongs to the calling application. This also enforces the
695 * 'read-only' nature of these values, i.e., this function cannot be
696 * used to manipulate the face.
697 *
698 * `value` is a void pointer because the values returned can be of
699 * various types.
700 *
701 * If either `value` is `NULL` or `value_len` is too small, just the
702 * required memory size for the requested entry is returned.
703 *
704 * The `idx` parameter is used, not only to retrieve elements of, for
705 * example, the FontMatrix or FontBBox, but also to retrieve name keys
706 * from the CharStrings dictionary, and the charstrings themselves. It
707 * is ignored for atomic values.
708 *
709 * `PS_DICT_BLUE_SCALE` returns a value that is scaled up by 1000. To
710 * get the value as in the font stream, you need to divide by 65536000.0
711 * (to remove the FT_Fixed scale, and the x1000 scale).
712 *
713 * IMPORTANT: Only key/value pairs read by the FreeType interpreter can
714 * be retrieved. So, for example, PostScript procedures such as NP, ND,
715 * and RD are not available. Arbitrary keys are, obviously, not be
716 * available either.
717 *
718 * If the font's format is not PostScript-based, this function returns
719 * the `FT_Err_Invalid_Argument` error code.
720 *
721 * @since:
722 * 2.4.8
