'Declaration
 
Public Interface IOcrZoneCharacters 
   Inherits System.Collections.Generic.ICollection(Of OcrCharacter), System.Collections.Generic.IEnumerable(Of OcrCharacter), System.Collections.Generic.IList(Of OcrCharacter), System.Collections.IEnumerable

'Usage

To get the recognized characters of a page, call IOcrPage.GetRecognizedCharacters after IOcrPage.Recognize or IOcrPage.RecognizeText.

To update the recognized characters of a page, call IOcrPage.GetRecognizedCharacters before calling IOcrDocument.Save, or IOcrDocument.SaveAsync, IOcrDocument.SaveXml or or IOcrDocument.SaveXmlAsync.

IOcrPageCharacters implements the standard IList, ICollection and IEnumerable interfaces with items of type IOcrZoneCharacters. Each item in the IOcrPageCharacters contains a collection of the character collections of the zones.

The IOcrZoneCharacters interface contains a collection of the characters of a particular zones.

IOcrZoneCharacters also implements IList, ICollection and IEnumerable interfaces but with items of type OcrCharacter. Each item in the IOcrZoneCharacters contains a collection of the characters of the zone.

For example, if you are interested in iterating through the characters of the 2nd zone in the page, you can do the following:

// Get the page characters IOcrPageCharacters pageCharacters = ocrPage.GetRecognizedCharacters(); // Get the 2nd zone characters. Note, the index is zero-based so the 2nd zone is at index 1 // You can also iterate through the pageCharacters collection and fine the IOcrZoneCharacters item with ZoneIndex = 1 IOcrZoneCharacters zoneCharacters = pageCharacters.FindZoneCharacters(1); // Loop through the characters foreach(OcrCharacter ocrCharacter in zoneCharacters) { // Do something with ocrCharacter }

For an example, refer to IOcrPage.GetRecognizedCharacters.
