| 587 * @function: | |
| 588 * FT_Get_PS_Font_Value | |
| 589 * | |
| 590 * @description: | |
| 591 * Retrieve the value for the supplied key from a PostScript font. | |
| 592 * | |
| 593 * @input: | |
| 594 * face :: | |
| 595 * PostScript face handle. | |
| 596 * | |
| 597 * key :: | |
| 598 * An enumeration value representing the dictionary key to retrieve. | |
| 599 * | |
| 600 * idx :: | |
| 601 * For array values, this specifies the index to be returned. | |
| 602 * | |
| 603 * value :: | |
| 604 * A pointer to memory into which to write the value. | |
| 605 * | |
| 606 * valen_len :: | |
| 607 * The size, in bytes, of the memory supplied for the value. | |
| 608 * | |
| 609 * @output: | |
| 610 * value :: | |
| 611 * The value matching the above key, if it exists. | |
| 612 * | |
| 613 * @return: | |
| 614 * The amount of memory (in bytes) required to hold the requested | |
| 615 * value (if it exists, -1 otherwise). | |
| 616 * | |
| 617 * @note: | |
| 618 * The values returned are not pointers into the internal structures of | |
| 619 * the face, but are `fresh' copies, so that the memory containing them | |
| 620 * belongs to the calling application. This also enforces the | |
| 621 * `read-only' nature of these values, i.e., this function cannot be | |
| 622 * used to manipulate the face. | |
| 623 * | |
| 624 * `value' is a void pointer because the values returned can be of | |
| 625 * various types. | |
| 626 * | |
| 627 * If either `value' is NULL or `value_len' is too small, just the | |
| 628 * required memory size for the requested entry is returned. | |
| 629 * | |
| 630 * The `idx' parameter is used, not only to retrieve elements of, for | |
| 631 * example, the FontMatrix or FontBBox, but also to retrieve name keys | |
| 632 * from the CharStrings dictionary, and the charstrings themselves. It | |
| 633 * is ignored for atomic values. | |
| 634 * | |
| 635 * PS_DICT_BLUE_SCALE returns a value that is scaled up by 1000. To | |
| 636 * get the value as in the font stream, you need to divide by | |
| 637 * 65536000.0 (to remove the FT_Fixed scale, and the x1000 scale). | |
| 638 * | |
| 639 * IMPORTANT: Only key/value pairs read by the FreeType interpreter can | |
| 640 * be retrieved. So, for example, PostScript procedures such as NP, | |
| 641 * ND, and RD are not available. Arbitrary keys are, obviously, not be | |
| 642 * available either. | |
| 643 * | |
| 644 * If the font's format is not PostScript-based, this function returns | |
| 645 * the `FT_Err_Invalid_Argument' error code. | |
| 646 * | |
