Function to create an OCR engine. This function allocates space for the new engine, which this program is subsequently responsible for deleting. This is the only way to create an OCR engine: you will need to call the vvxtrCreateRemoteEngine function.

Process one input document, which may have multiple pages. This function encompasses reading in the file, pre-processing, recognition, and document as well as subimage output.

Process one page. This function preprocesses and recognizes one page of image data. It then presents the user with the option of generating output of the recognized text or creating subimages from the original image. Output documents can cover multiple pages and multiple input documents, but for the purposes of this example, we limit output documents to one page of recognized text.

Basic image processing example. This routine prompts a user to submit an image file for recognition, then the user can choose to output a text or subimage results. An arbitrary number of input images may be recognized, and the user can choose which page to recognize. All OCR takes place within one OCR session (vvEngAPI::vvStartOCRSes), so for the best results, all input images recognized within one run of this program should be from the same batch or source, so that the internal training within the OCR session is productive.
