The user-written progress monitoring callback function.

Declaration:

Arguments:

mod	This variable holds the current state of the activated action (ProcessID, progress information etc).
lpUserData	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:

• IGE_REC_EXT_API_PROCESS_ABORTED_ERR if the user has requested the current processing to be aborted; processing will stop at the first suitable moment.
• IGE_REC_EXT_OK if the process can be continued normally.

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.
