OCR Text zones define an area of an image containing text that should be processed by the OCR engine. When the OCR engine encounters a text zone, it converts the underlying image to text.If implemented in your program, the Image Annotation Tool Button control and the Image Edit control let end users draw OCR zones on image documents to control OCR processing.
Depending on the type of zone drawn, OCR processing either occurs or doesn't occur. Using OCR zones increases the efficiency of OCR processing.
There are two types of OCR zones:
Text OCR Text zones define an area of an image containing text that should be processed by the OCR engine. When the OCR engine encounters a text zone, it converts the underlying image to text.
Picture OCR Picture zones define an area of an image containing one or more pictures that should not be processed by the OCR engine. When the OCR engine encounters a picture zone, it does not convert the underlying image to text; rather, it retains the image as a graphic.
Actual OCR processing is managed via the Image OCR control.
Note: OCR processing is available with Imaging for Windows Professional Edition V1.0, V1.1, and V2.0 only.
