Detailed Description

This interface represents a single character and is used to access its properties.

Usually you get the LOCRChar object from the ILOCRLine::Item() function. You can then use this interface to access to the character's placement, recognition result, quality, reduced image, etc., and draw the result on graphics windows.

Example Code

C++

ILOCRCharPtr charResult = lineResult->Item(i);
std::wstring charValue = charResult->String;

C#

LOCRChar charResult = lineResult.Item(i);
String charValue = charResult.String;

COM

ILOCRCharPtr charResult = lineResult->Item(i);
CString charValue = charResult->String;
