FNIG_REC_PROGRESS_MONITOR
API Reference Guide > Recognition Component API Reference > Recognition Component Functions Reference > Recognition Callback Functions > FNIG_REC_PROGRESS_MONITOR

The user-written progress monitoring callback function.

Declaration:

 
Copy Code
enumIGRecError ACCUAPI FNIG_REC_PROGRESS_MONITOR(
    LPAT_REC_PROGRESS_MONITOR mod, 
        LPAT_VOID lpUserData
);

Arguments:

Name Type Description
mod LPAT_REC_PROGRESS_MONITOR This variable holds the current state of the activated action (ProcessID, progress information etc).
lpUserData LPAT_VOID User data passed to the callback function by the Engine. The data to be passed can be set with IG_REC_progress_CB_register.

Return Value:

Supported Raster Image Formats:

See IG_REC_image_import.

Remarks:

This user-written callback procedure for progress monitoring must be registered by the IG_REC_progress_CB_register function. The Engine will continually invoke this registered callback procedure during different workflow processes (enumIGRecProcessId), providing a pointer to a AT_REC_PROGRESS_MONITOR structure that contains the current processing stage and a percentage indicator value. The application can provide progress indication for this procedure.

Enabling progress monitoring in the integrating application during the recognition process might cause a significant speed decrease, especially for zones on small images when they are recognized with the recognition module enumIGRecRecognitionModule.IG_REC_RM_OMNIFONT_MTX.
