The vertical resolution of the image being annotated in dots per inch. Usually you will return the resolution of the image you are using in AutomationRasterImage (RasterImage.YResolution), however, since you do not need to implement that property and can safely return null in some case, you must always manually implement AutomationImageDpiY to return the resolution in dots per inch. In this case, the resolution of the virtual image you will be using in automation or simply 0 to use the current screen resolution. You must trigger the IAnnAutomationControl.AutomationImageChanged event when the value of this property is changed.
