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.SaveXml

IOcrPageCharacters implements the standard Generic IList, Generic ICollection and Generic IEnumerable interfaces with items of type IOcrZoneCharacters. Thus 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 Generic IList, Generic ICollection and Generic 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, index is zero-based so 2nd zone is index 1
// You can also iterate through the pageCharacters collection and find the IOcrZoneCharacters item with ZoneIndex = 1
IOcrZoneCharacters zoneCharacters = pageCharacters.FindZoneCharacters(1);
// Loop through the characters
foreach(OcrCharacter ocrCharacter in zoneCharacters)
{
   // Do something with ocrCharacter
}
