<h5 id="GrapeCity_ActiveReports_Viewer_Win_Viewer_Zoom_remarks">Remarks</h5>
<div class="markdown level1 remarks"><p>The default value is <code>1f</code>, which corresponds to 100% zoom.</p>
<p>
Setting the zoom level to -1 or -2 adjusts the view to fit the width or the entire page within the viewer's display area, respectively. 
Specifying a positive value sets the zoom to that specific level.
