Retrieves the alphabet being used in a handwriting recognition context HRC
int GetAlphabetHRC( HRC hrc, LPALC lpalc, LPBYTE rgbfAlc )
Handle to the HRC
Address of a buffer that receives the current ALC_ values. If NULL, this
parameter is ignored.
Address of an array of bits or NULL. If NULL, this parameter is ignored. If lpalc
contains ALC_USEBITMAP and rgbfAlc
points to a valid array, the array is filled according to the bits set by the SetAlphabetHRC
Returns HRCR_OK if successful; otherwise, returns one of the following
||Invalid parameter or other error.
||The recognizer does not support this function.
is not NULL, the array it points to must be large enough to accommodate 256
bits (32 bytes). If the n
th bit is set, the n
th ANSI character is recognizable. Bits representing characters with ASCII
values less than 32 (the space character) currently have no meaning.
ALC_DEFAULT specifies the set of characters at or above ALC_SYSMINIMUM that
the recognizer can accurately distinguish.
For a description of alphabets and their relationship to a recognizer, see
"Configuring the HRC" in Chapter 5, "The Recognition Process."
