Visual Basic (Usage)Copy Code
Dim instance As IOcrZoneCharacters
C# 
public interface IOcrZoneCharacters

For an example, refer to IOcrPage.GetRecognizedCharacters.

Remarks

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. 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, 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
}
