Do you mean you want to limit the allowed values of zooming percent to a specific range? If yes, how exactly are you performing zooming?

Hi

yes.. i want to limit the Zooming action. i am using the following code for perfom zooming action.
****************************************************************************
_medicalViewer.SetAction(MedicalViewerActionType.Scale, MedicalViewerMouseButtons.Left, MedicalViewerActionFlags.Active)
********************************************************************

suppose when i perform zooming action that image size(width and height) will be increasing in this case(that image reaches original size(width and height) ) i want to limit or stop the scale action properties.

If you don't want the zoom factor to go above 100%, try to detect when the zooming is being done, and when the scale goes above 100%, change it using the Leadtools.MedicalViewer.MedicalViewerScale Class.
