OcrEngineImageSendOff Event

This event is raised before the OCR process starts, and after ImageSendOff for OCR pre-processing.

Namespace:  Atalasoft.Ocr
Assembly:  Atalasoft.dotImage.Ocr (in Atalasoft.dotImage.Ocr.dll) Version: (.NET 4.5.2, x86)
public event OcrImagePreprocessingEventHandler ImageSendOff


Type: Atalasoft.OcrOcrImagePreprocessingEventHandler
Any processing of the image in this event handler has no effect on the image that's included in a searchable PDF or other "Hidden Text Behind Image" formats. It is reasonable to threshold a color image to bi-tonal, and to strip away non-text content in this handler.
