Provides raw data and a correct interpretation of the data to the recognizer.
This function is provided only for compatibility with version 1.0 of the Pen
API and will not be supported in future versions. Use TrainHREC
BOOL TrainInk( LPRC lprc, HPENDATA hpndt, LPSYV lpsyv )
Address of an RC
structure, or NULL. If this parameter is NULL, the RC Manager replaces it
with a pointer to the global RC
structure, then calls the recognizer associated with the global RC
. If lprc
is not NULL, the RC Manager calls the recognizer identified by the hrec
member of the RC
Handle to an HPENDATA
object containing the ink to be trained. This parameter cannot be NULL.
Pointer to a string of SYV
symbol values terminated by SYV_NULL. This parameter cannot be NULL.
Returns TRUE if the ink described by the pen data could be trained; otherwise,
it returns FALSE.
Applications call TrainInk
with raw data accompanied by a correct interpretation of the data, so that
the recognizer can improve subsequent recognition. A second, more complex
training function for version 1.0 recognizers is provided by TrainContext
is called by an application to access the TrainInkInternal
function in the recognizer library. A private 1.0 recognizer must export both TrainInkInternal
, but the functions can simply return FALSE if the recognizer does not support
this type of training.
provides the lowest level of basic shape training. It requests the recognizer
to assign the meaning in lpsyv
to the ink in hpndt
. The recognizer should interpret the ink to meet that request.
In the most common case, lpsyv
points to a single character, and the recognizer will train a new shape based
on the ink and that character. In other cases, multiple SYV
symbol values can be passed, indicating that the ink represents multiple
characters. The recognizer must decide whether to simply add a new shape with a
meaning based on multiple SYV
symbol values or to segment the ink into separate shapes for each SYV
An application should check whether a recognizer supports training by calling ConfigRecognizer
with the WCR_TRAIN subfunction.
The trainer does not display an error message if TrainInk
returns FALSE. Error messages that occur when training fails must be handled
by the recognizer.
