I'm new here and using VB.NET 2017.

Can someone please give me an example how to OCR an image with text on it and then find a specific text phrase to locate it's center X Y coordinates?

Hello,

You can either use our OCR engine directly, or our Documents SDK for extracting the text from a file. If you'll only ever be processing images I'd probably recommend the OCR engine directly as it gives access to more details about the accuracy of the result (should you need that).

For our OCR engine, you'll mainly want to be comparing your search text to the OcrWords on the page. These can be found using the GetWords method of the IOcrPageCharacters class:
https://www.leadtools.com/help/leadtools/v20/dh/fo/iocrzonecharacters-getwords.html

We have a simply tutorial for getting started with our OCR engine both in C# and VB, you can use similar logic to the zone highlighting for your needs:
https://www.leadtools.com/help/leadtools/v20/dh/to/ocr-tutorial-adding-and-painting-zones.html

If you'd like a more complete example that shows how to highlight words throughout a document, we have a C# sample on our forums (you can easily translate C# to VB with a variety of tools online):
