Declarationprocedure ZoomIn(FitAndFullOnly: Boolean = False; X: Integer = -1; Y: Integer = -1);
Provides a convenient method to handle clicking of a "Zoom In" button. Each time ZoomIn
is called it increases the zoom by a logical step, e.g. 50 to 75, 75 to 100, etc. (FitAndFullOnly = False).
It also includes "Fit to Window" as one of the steps.
If FitAndFullOnly = True, then there are only two steps, "Fit to Window" or 100% zoom.
If X and Y are specified, then it will zoom into
the specified position (in client coordinates). Zooming will be smooth if miSmoothZoom is specified for MouseInteractGeneral
will only have a temporary effect if AutoShrink
is enabled, unless you add iedoDisableAutoFitWhenZoom
