function showSelection( 
   imageRectangle : Rectangle
) : (Any);

var resultVar = instanceOfPageView.showSelection(Rectangle);

Parameters

imageRectangle

The location at which the selection should be placed. The units of the rectangle 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.

This function causes the viewer to show a selection around the specified rectangle of 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. If the viewer does not have an open image, this function will do nothing.
