Hi Chitrang,

Thanks for contacting us regarding PDFJS Express!

Fortunately, the information that quads contain is good enough to programmatically create a highlight annotation.

We have a **text-position** sample that shows the code you might be interested in. The sample is available under the **samples/advanced/text-position** folder in the download package from [https://pdfjs.express/documentation/get-started/manually](https://pdfjs.express/documentation/get-started/manually).

The function in the sample that you want to take a look at is **highlightText**.

Let me know how this works and if you have any other questions!

Best Regards,  
Zhijie
