* @description: | |
* Retrieve the value for the supplied key from a PostScript font. | |
* | |
* @input: | |
* face :: | |
* PostScript face handle. | |
* | |
* key :: | |
* An enumeration value representing the dictionary key to retrieve. | |
* | |
* idx :: | |
* For array values, this specifies the index to be returned. | |
* | |
* value :: | |
* A pointer to memory into which to write the value. | |
* | |
* valen_len :: | |
* The size, in bytes, of the memory supplied for the value. | |
* | |
* @output: | |
* value :: | |
* The value matching the above key, if it exists. | |
* | |
* @return: | |
* The amount of memory (in bytes) required to hold the requested | |
* value (if it exists, -1 otherwise). | |
* | |
* @note: | |
* The values returned are not pointers into the internal structures of | |
* the face, but are `fresh' copies, so that the memory containing them | |
* belongs to the calling application. This also enforces the | |
* `read-only' nature of these values, i.e., this function cannot be | |
* used to manipulate the face. | |
* | |
* `value' is a void pointer because the values returned can be of | |
* various types. | |
* | |
* If either `value' is NULL or `value_len' is too small, just the | |
* required memory size for the requested entry is returned. | |
* | |
* The `idx' parameter is used, not only to retrieve elements of, for | |
* example, the FontMatrix or FontBBox, but also to retrieve name keys | |
* from the CharStrings dictionary, and the charstrings themselves. It | |
* is ignored for atomic values. | |
* | |
* PS_DICT_BLUE_SCALE returns a value that is scaled up by 1000. To | |
* get the value as in the font stream, you need to divide by | |
* 65536000.0 (to remove the FT_Fixed scale, and the x1000 scale). | |
* | |
* IMPORTANT: Only key/value pairs read by the FreeType interpreter can | |
* be retrieved. So, for example, PostScript procedures such as NP, | |
* ND, and RD are not available. Arbitrary keys are, obviously, not be | |
* available either. | |
* | |
* If the font's format is not PostScript-based, this function returns | |
* the `FT_Err_Invalid_Argument' error code. | |
