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 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 }
Target Platforms: Microsoft .NET Framework 2.0, Windows 2000, Windows XP, Windows Server 2003 family, Windows Server 2008 family, Windows Vista, Windows 7
