Hi,

I want to provide a find text function on an image. For this, I need to get the text as well as its position on the image so that I can draw a rectangle/box around the selected text on the image. How can I achieve this. An immediate response would be appreciated.

Thanks,

Suresh

If you are referring to LEADTOOLS 14, then you can get the recognized word and the position of each word.

If you are using any other version rather than LEAD14, then let me know, The exact
method depends on the LEADTOOLS version (12, 13, 14, etc) and programming
interface (DLL API, C++ Classes, etc.) that you are using.

For LEADTOOLS 13, you can use the VERIFYCALLBACK Function, which gives you all words and their information in a VERIFYINFO structure.

I would like to know if there is a similiar function in version 12.1, since I don't see VERIFYCALLBACK in the 12.1 documentation.

Hello,

You can try using the RecognizeEvent event (OCR Control). You will receive the
verified text in the pszText parameter, and the recognized text position in the
nWordLeft, nWordTop, nWordWidth and nWordHeight. Set the VerifierMode property (OCR Control) to OCRVER_CHAR.

Note: you will note be able to retrieve the above information only if the OCR nStatus = OCRSTATUS_QUESTION.

For more information, please refer to the LEADTOOLS OCR OCX Help file, and read the following topics:
- RecognizeEvent event (OCR Control)
- StatusRecognizeEvent property (OCR Control)
- TextRecognizeEvent property (OCR Control)

Thanks,
