IOcrZoneCharacters Interface

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

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`1, ICollection`1 and IEnumerable`1 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`1, ICollection`1 and IEnumerable`1 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 }
