Comments

This function updates ppRecogWords with an array containing all of the recognized words for the specified recognized page. Memory for the array of structures pointed to by ppRecogWords is allocated by this function.

This function also updates the variable pointed to by pnWordsCount with the number of recognized words.

Once the ppRecogWords parameter is no longer needed, free the memory associated with it by calling the L_Doc2FreeRecognizedWords function.

This function should only be called after successfully starting a recognition process by calling the L_Doc2Recognize function.

The L_Doc2GetRecognizedWords function just combines the recognized characters for the specified page into words. To change the contents of the recognized words, change the set of recognized characters by calling the L_Doc2SetRecognizedCharacters function. To save the updated recognized characters to a file, call the L_Doc2SaveResultsToFile function.
