In This Topic
    showEmptySelection Method
    In This Topic
    Show an empty selection.
    Syntax
    ASP.NET Ajax JavaScript (Specification) 
    function showEmptySelection( 
       imagePoint : Point
    ) : (Any);
    ASP.NET Ajax JavaScript (Usage) 
    var resultVar = instanceOfPageView.showEmptySelection(Point);

    Parameters

    imagePoint
    The location at which the selection should be placed. The units of the point are the same as that for pageWidth (pixels for raster images and points for PDF images). The selection will be clipped to the bounds of the actual image.
    Remarks

    This function causes the viewer to show a zero-sized selection at the specified point on the image, although that will not affect the visual appearance of the viewer until the browser has some idle time or you call the display function. Normally, you will want to use showEmptySelection and extendSelection together to define a rectangle. Start by calling showEmptySelection, followed by one or more calls to extendSelection. If the viewer does not have an open image, this function will do nothing.
