Hi there,

We have a guide here to normalize coordinates between window and PDF pages:

However you will need to convert these values to normalize it between 0 and 1.

Hello Kevin,

Thank you for the answering and also I wonder if it’s possible to get the current zoom ratio of the viewer?

Like in this picture is there a function I can get the number 88?

To get the current zoom level of the document, please use the getZoomLevel API:
