Hi there,

I am building a WPF application using Leadtools and I would like to be able to detect when the mouse is moving and retrieve the coordinates. Subscribing to the ImageViewer.MouseMove allows to get a callback every time the mouse moves over the image viewer but the problem is that the image does not take all the viewer space so I am unable to get the right coordinates. I have seen the AnnAutomation.SetCursor event which does trigger when over the RasterImage but the problem is that it is called only when entering the image regions not when moving inside the region.

Is there anything you could recommend to achieve this behavior?

Thank you

In the LEADTOOLS21 file folder we have an example demo that can show you how to return the coordinates as you move through the viewer.

This demo is designed to show the difference between the viewer and the SVG coordinates but will still serve as an excellent working example of how to achieve this.

I confirm that using the `ConvertPoint` function on the image viewer gets me the right coordinates.

Thank you.
