ImageGear .NET v25.2 - Updated
extendSelection Method

ImageGear.Web.UI Library > ImageGear.Web.UI Namespace > PageView class : extendSelection Method
Adjust the current selection.
Syntax
ASP.NET Ajax Javascript (Specification) 
function extendSelection( 
   imagePoint : Point
) : (Any);
ASP.NET Ajax Javascript (Usage) 
var resultVar = instanceOfPageView.extendSelection(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 adjust the current selection so the given point is at one of the corners, 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.
