Leadtools.Forms.Ocr Namespace : IOcrPageCharacters Interface



The recognized characters collection of a page.

Syntax

Visual Basic (Declaration) 
Public Interface IOcrPageCharacters 
   Inherits ICollection(Of IOcrZoneCharacters)IEnumerable(Of IOcrZoneCharacters)IList(Of IOcrZoneCharacters)IEnumerable 
Visual Basic (Usage)Copy Code
Dim instance As IOcrPageCharacters
C++/CLI 
public interface class IOcrPageCharacters : public ICollection<IOcrZoneCharacters>IEnumerable<IOcrZoneCharacters>IList<IOcrZoneCharacters>IEnumerable  

Example

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 IList, ICollection and 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 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, 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
            }
