Hello everyone,

Here is simple code how to resize BitmapViewer web control on client side:

Code:
<%@ Page Language="vb" AutoEventWireup="false"%>
<%@ Register TagPrefix="aur" Namespace="Aurigma.GraphicsMill.WebControls" Assembly="Aurigma.GraphicsMill.WebControls" %>
<script runat="server">
Private Sub Page_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
	If Not Page.IsPostBack Then
		BitmapViewer1.Bitmap.Load(Server.MapPath("TestImages/building.jpg"))
	Else
		'Check whether control width and height were changed on client side
		If Request.Form("newWidth")<>"" And Request.Form("newHeight")<>"" Then
			BitmapViewer1.Width=Unit.op_Implicit(Int32.Parse(Request.Form("newWidth")))
			BitmapViewer1.Height=Unit.op_Implicit(Int32.Parse(Request.Form("newHeight")))
		End If
	End If
End Sub
</script>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN">
<HTML>
	<HEAD>
		<LINK href="Style.css" type="text/css" rel="stylesheet">
		<script language="javascript">
function resizeBitmapViewer(){
	var bitmapViewer1=document.getElementById("<%=BitmapViewer1.ClientID%>");
	var newWidth=640;
	var newHeight=480;
	
	//Resize control
	bitmapViewer1.style.width=newWidth+"px";
	bitmapViewer1.style.height=newHeight+"px";
	
	//Refresh control
	bitmapViewer1.delayedRefresh();

	//Save width and height in hidden form fields for syncing on server-side
	document.getElementById("newWidth").value=newWidth;
	document.getElementById("newHeight").value=newHeight;	
}
			</script>
	</HEAD>
	<body>
		<form id="Form1" runat="server">
			<input type="button" value="Resize Bitmap Viewer" onclick="resizeBitmapViewer()">
			
			<input type="hidden" value="" name="newWidth" id="newWidth">
			<input type="hidden" value="" name="newHeight" id="newHeight">
	
			<asp:Button Runat="server" Text="Make Roundtrip"></asp:Button>	
		
			<aur:bitmapviewer id="BitmapViewer1" runat="server" Width="344" height="270"
				BorderWidth="2" BorderStyle="Inset" ScrollBarsStyle="Auto" BackColor="White" Zoom="4"></aur:bitmapviewer>
		</form>
	</body>
</HTML>
