Please can you tell me using IEViewer how to zoom around a particular point. For Example, I have EnableZoomOnSelect set on. After the zoom the user may want to rotate the image but have the zoomed area still visible after the zoom. At the moment because the image is larger than the client area, the image rotates but the zoomed area is not within the client area anymore. The user must zoom out and in again to locate the area again.
Regards

You could try to use ZoomAt to zoom at a x,y value:
TImageEnView.ZoomAt
Declaration
procedure ZoomAt(x, y: integer; ZoomVal: double; Center:boolean=true);
Description
This method zooms by the ZoomVal percentage centered at the point x,y.
If the optional Center parameter if False, the zooming center is x, y, otherwise (the default) it is the center of image.

| Thanks, I did see this method and it is likely the solution. I just need to figure out how to get the center x,y cords from IEViewer from the center point that is currently on view in the client area, not the center point of the image. I need to read some more to find the correct method. I tried to debug the properties but nothing jumped out as being the current view coordinates. |
