The ImageGear Recognition Component must be attached to the Core component and initialized before using it.
Use the following call to attach the Recognition component:
C |
Copy Code
|
---|---|
AT_ERRCODE errCode;
errCode = IG_comm_comp_attach("REC");
|
If the component has been attached, the function returns IGE_SUCCESS.
To check whether the Recognition component has been already attached, call IG_comm_comp_check("REC"); if the function returns TRUE then the Recognition component has been attached.
After the Recognition component has been attached, the recognition session must be initialized with the function IG_REC_initialize(). The function returns 0 if the session has been initialized successfully. Otherwise, the return value is a number of errors encountered during the initialization.
Recognition component requires additional resource files to be available. See description of IG_REC_initialize() for information on where these files should be located such that the component can access them.
Function IG_REC_close() closes the recognition session if it is no longer necessary. After closing the session, any calls to the recognition functions are not allowed (except IG_REC_initialize()). To start a new recognition session call IG_REC_initialize() again.
