I found the source OCR can only recognize English characters.
And I found a sentences in the OCR source code " cmbLanguage.Items.Add(IEOCRLanguageList[OCR_English_language].DisplayName);"
My questions and request is :
Could somebody tell me how to add other language to the OCR, such as simple Chinese?
Thanks a lot.

Hi Yuanyi

Download the OCR languages from:

http://www.imageen.com/files/Reg/IEVision_OCR/IEVision_AllLanguages.zip

Copy the Simplified or Traditional Chinese TrainedData file to the same folder as your EXE and call as follows:

sLanguage := 'chi_sim'; // Simplified Chinese
if FileExists( IncludeTrailingPathDelimiter( ExtractFilePath( Application.ExeName )) + sLanguage + '.traineddata' ) = False then
raise Exception.create( 'Language file not found' );
OCR := IEVisionLib.createOCR( sLanguage )

More Info: https://www.imageen.com/help/TIEVisionLibrary.createOCR.html

Also, if you try the OCR demo from Demos\IEVision\OCR\. It will automatically support (show as an option) any language files found in the same folder as the demo exe.
