RecognizeData
- 0 2.0
Converts the data in an HPENDATA object to recognized symbols.
Note This function is provided only for compatibility with version 1.0 of the Pen
API and will not be supported in future versions.
REC RecognizeData( LPRC lprc, HPENDATA hpndt )
Parameters
lprc
Address of an RC structure.
hpndt
Handle to an HPENDATA object.
Return Value
Returns REC_DONE if successful, or an REC_ error code if an error occurs.
Comments
RecognizeData recognizes data in an HPENDATA object and returns the results to the window specified in the RC structure. RecognizeData is similar to Recognize. The difference is that in RecognizeData, the input data comes from a buffer of points already collected instead of
from the tablet driver. Members pertaining to the end of recognition in the RC structure are ignored.
RecognizeData can return REC_BUSY if the recognizer is not reentrant. A recognizer is not
guaranteed to return the same results for identical input. This is because
persistent states, such as the current average size of writing or the position of
the baseline, can affect recognition results. In addition, training may change
the prototypes against which the data is being compared.
RecognizeData attempts to convert the pen data to PDTS_STANDARDSCALE if it is not already
in standard scale. If the conversion fails (for example, because the data was in
an application-specific scale PDTS_ARBITRARY), the data is still passed to the
recognizer. A recognizer may return an error code (REC_BADHPENDATA) for data
in a scale it cannot handle.

Nostalgia .Net |

.Net is powerful, but not all-powerful, so sometimes we need to use Win32 API for our .Net applications. It's simple enough with Platform Invoke if you have Win32 skill, but we do not always have time to dig the ancient documentation, declare the special types that are compatible with Win32, find the values of the Win32's constants and so on. Nostalgia .Net offers several simple-to-use classes, and components that will allow you to forget about the headache of Win32 and just use the power of Win32 in your application the same way as you use the native. Net classes. More » |
